ABSTRACT

Resumen Introducción: Las lesiones de grandes vasos del tórax por traumatismo torácico (TTLGV) son un grupo heterogéneo de lesiones con alta morbimortalidad que constituyen un 0,3-10% de los hallazgos en el traumatismo torácico (TT). Objetivos: Describir características, tratamientos y variables asociadas a mortalidad en pacientes hospitalizados con TTLGV. Material y Métodos: Estudio analítico-observacional. Período enero-1981 y diciembre-2020. Revisión de protocolos de TT prospectivos y fichas clínicas. Se clasificaron los TTLGV según American Association for the Surgery of Trauma (AAST), se calcularon índices de gravedad del traumatismo: Injury Severity Score (ISS), Revised Trauma Score Triage (RTS-T) y Trauma Injury Severity Score (TRISS). Se realizó análisis univariado y multivariado con cálculo de Odds Ratio (OR) para variables asociadas a mortalidad. Se usó SPSS25®, con pruebas UMann Whitney y chi-cuadrado, según corresponda. Resultados: de un total 4.577 TT, 97 (2,1%) cumplieron criterios de inclusión. Hombres: 81 (91,8%), edad promedio: 32,3 ± 14,8 años. TT penetrante: 65 (67,0%). Lesión de arterias axilo-subclavias en 39 (40,2%) y aorta torácica en 31 (32,0%) fueron las más frecuentes. Fueron AAST 5-6: 39 (40,2%). Tratamiento invasivo: 87 (89,7%), de éstos, en 20 (20,6%) reparación endovascular, 14 (14,4%) de aorta torácica. Cirugía abierta en 67 (69,1%). Mortalidad en 13 (13,4%), fueron variables independientes asociadas a mortalidad el shock al ingreso (OR 6,34) e ISS > 25 (OR 6,03). Conclusión: En nuestra serie, los TTLGV fueron más frecuentemente de vasos axilo-subclavios y aorta torácica. El tratamiento fue principalmente invasivo, siendo la cirugía abierta el más frecuente. Se identificaron variables asociadas a mortalidad.


Background: Thoracic great vessel injuries in thoracic trauma (TTGVI) are a heterogeneous group of injuries with high morbimortality that constituting 0.3-10% of the findings in thoracic trauma (TT). Aim: To describe characteristics, treatments and variables associated with mortality in hospitalized patients with TTGVI. Methods: Observational-analytical study. Period January-1981 and December-2020. Review of prospective TT protocols and clinical records. TTGVI were classified according to American Association for the Surgery of Trauma (AAST), trauma severity index were calculated: Injury Severity Score (ISS), Revised Trauma Score Triage (RTS-T) and Trauma Injury Severity Score (TRISS). Univariate and multi- variate analysis was performed with calculation of Odds Ratio (OR) for variables associated with mortality. SPSS25® was used, with U Mann Whitney and chi-squared tests, as appropriate. Results: From a total of 4.577 TT in the period, 97 (2.1%) met the inclusion criteria. Males: 81 (91.8%), mean age: 32.3 ± 14.8 years. Penetrating TT: 65 (67.0%). Axillary-subclavian artery lesions in 39 (40.2%) and thoracic aorta in 31 (32.0%) were more frequent. AAST 5-6: 39 (40.2%). Invasive treatment: 87 (89.7%), of these, in 20 (20.6%) endovascular repair, 14 (14.4%) of thoracic aorta. Open surgery in 67 (69.1%). Mortality in 13 (13.4%), shock on admission was independently associated with mortality (OR 6.34) and ISS > 25 (OR 6.03). Conclusión: In our series, TTGVI were more frequent in axillary-subclavian vessels and thoracic aorta. Treatment was mainly invasive, with open surgery being the most frequent. Variables associated with mortality were identified.

ABSTRACT

Introducción. En las últimas décadas, la terapia endovascular en aneurismas aórticos abdominales ha ganado un papel representativo en los escenarios quirúrgicos, lo que nos motivó a conocer los resultados de este procedimiento en nuestra población. Métodos. Estudio analítico retrospectivo en el cual se incluyeron los primeros 50 casos de aneurismas aórticos abdominales con terapia endovascular, en la ciudad de Manizales, Colombia, entre los años 2015 y 2021. Se describió la población estudiada, la relación de los antecedentes prequirúrgicos con las complicaciones posoperatorias, la estancia hospitalaria y la mortalidad. Resultados.La edad promedio fue de 73 años, el sexo predominante fue el femenino (72 %), el aneurisma fusiforme fue el tipo más frecuente (63,3 %), con un diámetro promedio de 70 mm (+/- 17,3 mm). En relación con los antecedentes, el más frecuente fue hipertensión arterial (86 %), encontrándose una asociación entre la presencia de enfermedad pulmonar obstructiva crónica e hipertensión arterial con las complicaciones. Se encontró también relación entre el valor de creatinina con las complicaciones. Las complicaciones tempranas fueron de carácter leve en la mayoría de los casos (30,6 %), a diferencia de las tardías, que fueron principalmente graves (12,5 %), asociadas a una mortalidad del 10,2 % y una estancia hospitalaria promedio de 10,8 días (mediana de 5 días). Conclusiones. La población analizada tiene una alta carga de morbilidad, en la cual factores como los antecedentes médicos prequirúrgicos y la función renal, se asocian con una mayor morbilidad postquirúrgica y mortalidad.


Introduction. In recent decades, endovascular therapy in abdominal aortic aneurysms has gained a representative role in surgical scenarios, which motivated us to learn about the results of this procedure in our population. Methods. Retrospective analytical study, which included the first 50 cases of abdominal aortic aneurysms with endovascular therapy, in the city of Manizales, Colombia, between 2015 and 2021. The study population was described as the relationship between pre-surgical history and post-operative complications, hospital stay and mortality. Results. The average age was 73 years, the predominant sex was female (72%), the fusiform aneurysm was the most frequent type (63.3%), with an average diameter of 70 mm (± 17.3 mm). In relation to history, the most frequent was arterial hypertension (86%), finding an association between the presence of chronic obstructive pulmonary disease and arterial hypertension with complications. A relationship was also found between the creatinine value and complications. Early complications were mild in most cases (30.6%), unlike late complications, which were mainly serious (12.5%), associated with a mortality of 10.2% and a hospital stay average of 10.8 days (median of 5 days). Conclusions. The analyzed population has a high burden of morbidity, in which factors such as pre-surgical medical history and renal function are associated with greater post-surgical morbidity and mortality.

ABSTRACT

Introducción: el síndrome de vena cava superior resulta de la obstrucción del flujo sanguíneo a través de este vaso. Casi la totalidad de los casos en la actualidad se asocian con tumores malignos. Existen controversias acerca del manejo apropiado de este cuadro. Actualmente, las terapias endovasculares son consideradas de elección. Materiales y métodos: se recolectaron y describieron, a partir de datos de la historia clínica electrónica, los casos de pacientes mayores de 18 años internados ­de forma consecutiva, que desarrollaron el síndrome­ en el Hospital Italiano de Buenos Aires en 2021. Se constataron las características basales, los tratamientos recibidos y los desenlaces clínicos intrahospitaliarios de cada uno de ellos. Resultados: un total de cinco pacientes fueron incluidos en el presente estudio y seguidos durante su instancia intrahospitalaria. Todos los casos descriptos fueron secundarios a enfermedades oncológicas. La mayoría de los pacientes presentaron un cuadro de moderada gravedad según las escalas utilizadas. En cuatro de cinco pacientes se optó por terapias endovasculares y dos de ellos fallecieron durante la internación. Discusión: existen controversias respecto del tratamiento óptimo del síndrome de vena cava superior, y heterogeneidad en la práctica clínica. Los estudios futuros deberían centrarse en identificar a aquellos pacientes que más probablemente se beneficien de las estrategias terapéuticas endovasculares, anticoagulantes o antiagregantes. (AU)


Introduction: superior vena cava syndrome results from an obstruction of blood flow through this vessel. Currently, almost all cases are associated with malignancies. There are controversies about the optimal management of this syndrome. Endovascular therapies are considered the first-line therapy. Material and methods: we collected clinical, laboratory and pharmacological data from patients admitted at the Hospital Italiano de Buenos Aires, between January 1st and November 1st 2021 with a diagnosis o superior vein cava syndrome. Baseline characteristics, treatment strategies and clinical outcomes were recorded. Results: a total of five patients were included in the present study. All cases were malignancy-related. Most of the patientsdeveloped moderate symptoms. Four out of five patients were treated with endovascular therapies and two patients died during hospitalization. Discussion: controversies regarding optimal management of the superior vena cava syndrome remain. Future research should focus on identifying those patients who are most likely to benefit from endovascular, anticoagulant or antiplatelet therapeutic strategies. (AU)

ABSTRACT

Objectives To establish the success rate in endovascular internal carotid artery (ICA) stenosis recanalization using the double-layer stent Casper-RX (Microvention, Inc 35 Enterprise, Aliso Viejo, California, United States of America) and to identify the main comorbidities in individuals with ICA stenosis, morphological characteristics of the stenosis, diagnostic methods, intraoperative complications, as well as morbidity and mortality within 30 days of the surgical procedure. Materials and Methods Retrospective analysis of 116 patients undergoing ICA angioplasty with a degree of stenosis > 70% using Casper-RX stenting who underwent this procedure from April 2015 to December 2019. Results Technical success was achieved in 99.1% of the patients. Three of them had postprocedural complications: one transient ischemic attack (TIA) and two puncture site hematomas. A cerebral protection filter was not used in only two procedures, as these consisted of dissection of the carotid. There was satisfactory recanalization and adequate accommodation of the stents in the previously stenosed arteries, with no restenosis in 99.4% of the cases. Conclusion The endovascular treatment of extracranial carotid stenoses using the Casper-RX stent showed good applicability and efficacy. Although only two cases of thromboembolic complications occurred during the procedure, fu

ABSTRACT

Objective Glomus jugulare tumors, or tympanojugular paragangliomas, are rare, highly vascularized skull base tumors originated from paraganglion cells of the neural crest. With nonabsorbable embolic agents, embolization combined with surgery has become the norm. The authors assess the profile and outcomes of patients submitted to preoperative embolization in a Brazilian tertiary care hospital. Methods The present study is a single-center, retrospective analysis; between January 2008 and December 2019, 22 embolizations were performed in 20 patients in a preoperative character, and their medical records were analyzed for the present case series. Results Hearing loss was the most common symptom, present in 50% of the patients, while 40% had tinnitus, 30% had dysphagia, 25% had facial paralysis, 20% had hoarseness, and 10% had diplopia. In 7 out of 22 embolization procedures (31%) more than a single embolic agent was used; Gelfoam (Pfizer, New York, NY, USA) was used in 18 procedures (81%), in 12 of which as the single agent, followed by Embosphere (Merit Medical, South Jordan, UT, USA) (31%), Onyx (Medtronic, Minneapolis, MN, USA) (9%), and polyvynil alcohol (PVA) and Bead Block (Boston Scientific, Marlborough, MA, USA) in 4,5% each. The most common vessel involved was the ascending pharyngeal artery, involved in 90% of the patients, followed by the posterior auricular artery in 15%, the internal maxillary artery or the occipital artery in 10% each, and the superficial temporal or the lingual arteries, with 6% each. Only one patient had involvement of the internal carotid artery. No complications from embolization were recorded. Conclusions Preoperative embolization of glomus tumors is safe and reduces surgical time and complications, due to the decrease in size and bleeding.

ABSTRACT

Resumo Pacientes portadores de doença arterial obstrutiva periférica com isquemia crítica do membro associada a infecção de prótese vascular apresentam elevadas taxas morbimortalidade e alto risco de perda do membro. Apresentamos o caso de um paciente masculino de 76 anos com isquemia crítica do membro inferior esquerdo associada a infecção de prótese vascular femoropoplítea. Utilizamos abordagem híbrida para o tratamento com acesso cirúrgico das regiões inguinais e poplíteas, sendo a prótese vascular utilizada como acesso endovascular para recanalização direta da artéria femoral superficial devido a obstrução longa e extensa calcificação, que impediram as tentativas iniciais de tratamento endovascular. Após a recanalização endovascular, a prótese infectada foi retirada. O avanço das técnicas e materiais endovasculares em associação com a cirurgia aberta permitem novas soluções para pacientes quando os procedimentos habituais falham.


Abstract Patients with severe arterial obstructive disease and critical limb ischemia associated with vascular graft infection have elevated morbidity and mortality rates and are at high risk of limb loss. We present the case of a 76-year-old male patient with left lower limb critical ischemia and a femoropopliteal vascular graft infection. We used a hybrid treatment approach with an open surgical approach to the inguinal and popliteal regions and used the vascular prosthesis as endovascular access for direct recanalization of the superficial femoral artery, because the long occlusion and extensive calcification had frustrated initial attempts at endovascular treatment. After endovascular recanalization, the infected graft was removed. Used in conjunction with open surgery, advances in endovascular techniques and materials offer new solutions for patients when usual procedures fail.

ABSTRACT

Abstract Endovascular embolization of arteries feeding pulmonary sequestrations is a growing therapeutic option. A 51-year-old woman with chest pain and hemoptysis was admitted. During hospitalization she presented 150 mL hemoptysis, hypotension, and hematocrit fell to 23.3%. Contrast-enhanced computed tomography confirmed a pulmonary sequestration irrigated by an aneurysmal artery from the abdominal aorta. The patient underwent endovascular coil embolization of the artery feeding the aneurysm and an Amplatzer device was deployed in the proximal third of the sequestration artery. Subsequent contrast-enhanced computed tomography confirmed complete thrombosis of the aberrant artery feeding the aneurysm and absence of irrigation of the pulmonary sequestration. At 56 months follow-up the patient remains asymptomatic, tomography showed involution of the sequestration and complete thrombosis of the aberrant artery. The challenges presented by the different treatment alternatives are discussed.


Resumo A embolização endovascular das artérias que alimentam os sequestros pulmonares é uma opção terapêutica em crescimento. Uma mulher de 51 anos com dor torácica e hemoptise foi internada. Durante a internação, ela apresentou hemoptise de 150 mL, hipotensão e queda do hematócrito para 23,3%. A tomografia computadorizada com contraste confirmou um sequestro pulmonar irrigado por uma artéria aneurismática originária da aorta abdominal. A paciente foi submetida a embolização endovascular da artéria que alimentava o aneurisma com uso de coils e dispositivo Amplatzer no terço proximal da artéria sequestrante. A tomografia subsequente confirmou a trombose completa da artéria aberrante que alimentava o aneurisma e a ausência de irrigação dentro do sequestro pulmonar. No seguimento de 56 meses, a paciente permanecia assintomática, e a tomografia mostrou involução do sequestro e trombose completa da artéria aberrante. Os desafios apresentados pelas diferentes alternativas de tratamento são discutidos neste artigo.

ABSTRACT

RESUMO Contexto A doença arterial obstrutiva periférica apresenta alta prevalência, sendo associada a elevado risco de eventos cardiovasculares. A intervenção cirúrgica ou endovascular faz-se necessária na isquemia crítica do membro. Objetivos Avaliar a distribuição de realização de revascularizações abertas e endovasculares nas diferentes regiões do Brasil, analisando os custos para o sistema de saúde e a mortalidade relacionada a esses procedimentos. Métodos Foi realizado um estudo epidemiológico observacional transversal descritivo para avaliar as cirurgias abertas e endovasculares realizadas no sistema público de saúde do Brasil entre 2010 e 2020. Os dados foram coletados através do Departamento de Informática do SUS (Datasus). Resultados No período analisado, foram registradas 83.218 internações para realização de cirurgias abertas e endovasculares, com um custo total de R$ 333.989.523,17. Houve predominância das internações para os procedimentos percutâneos (56.132) em relação aos cirúrgicos convencionais (27.086). As Regiões Sudeste e Sul concentraram a maior parte do total de procedimentos realizados no país (83%), enquanto a Região Norte foi a que apresentou a menor taxa de internação. Observou-se uma tendência decrescente para os procedimentos abertos, e uma tendência crescente para os endovasculares. A média de permanência hospitalar foi menor nos procedimentos endovasculares (5,3 dias) em relação aos abertos (10,2 dias). Além disso, notou-se uma maior taxa de mortalidade hospitalar relacionada à revascularização aberta em relação à endovascular (5,24% versus 1,56%). Conclusões As técnicas endovasculares consistiram em uma abordagem dominante no tratamento cirúrgico da isquemia crítica, apresentando menor taxa de mortalidade hospitalar e menor tempo de internação quando comparada às cirurgias abertas.


ABSTRACT Background Peripheral artery disease (PAD) has high prevalence and is associated with high risk of cardiovascular events. Surgical or endovascular intervention is necessary in chronic limb-threatening ischemia. Objectives To evaluate the distribution of open and endovascular revascularizations in different regions of Brazil, analyzing the health system costs and mortality related to these procedures. Methods A descriptive, cross-sectional, observational, epidemiological study was carried out to evaluate open and endovascular surgeries performed on the SUS public healthcare system in Brazil, from 2010 to 2020. Data were collected from the SUS Department of Informatics (Datasus). Results Over the period analyzed, 83,218 admissions for open and endovascular surgeries were registered, with a total cost of R$ 333,989,523.17. There were more hospital admissions for percutaneous procedures (56,132) than for conventional surgery (27,086). Most of the procedures (83%) were performed in the country's Southeast and South regions, while the North region had the lowest number of procedures. Over the period evaluated, there was a decreasing trend for open procedures and an increasing trend for endovascular procedures. The average hospital stay was shorter for endovascular procedures (5.3 days) than for open surgery (10.2 days). The analysis of mortality related to these procedures revealed a higher rate of in-hospital mortality associated with open revascularization than with endovascular (5.24% vs. 1.56%). Conclusions Endovascular techniques constituted the primary approach for revascularization treatment in critical limb-threatening ischemia, with a lower in-hospital mortality rate and shorter hospital stay when compared to open surgeries.

ABSTRACT

Resumo A doença de Behçet (DB) é caracterizada por ser uma doença rara, crônica, recidivante, inflamatória e multissistêmica. Quanto ao diagnóstico, não existe nenhum teste universalmente descrito; logo, ele é feito de maneira clínica, por meio da presença da sua tríade clássica de sinais: úlceras orais, úlceras genitais e uveíte (inflamação do trato uveal do olho). O objetivo deste estudo foi avaliar a importância do tratamento endovascular na doença de Behçet, sendo que a revisão de literatura para obter essa resposta foi realizada a partir de 30 artigos publicados entre 2002 e 2021. A DB acomete tanto o sistema venoso quanto o arterial. A ruptura de aneurismas é a principal causa de morte e necessita de tratamento, podendo ser clínico, cirúrgico aberto ou por via endovascular. A cirurgia endovascular vem ganhando espaço no tratamento cirúrgico nos casos de aneurismas arteriais, inclusive nos relacionados com DB, apesar de a terapia de escolha ainda ser controversa.


Abstract Behçet's Disease (BD) is a rare, chronic, relapsing, inflammatory, and multisystemic disease. There is no universally described test for confirming diagnosis, so it is made clinically, on the basis of its classic triad of signs: oral ulcers, genital ulcers, and uveitis (inflammation of the uveal tract of the eye). The aim of this study is to evaluate the importance of endovascular treatment in Behçet's disease. The literature review conducted to achieve this objective covered 30 articles published between 2002 and 2021. Behçet's Disease affects both the venous and arterial systems. Rupture of aneurysms is the main cause of death and thus requires treatment, which can be clinical, open surgical, or endovascular. Endovascular surgery has been gaining ground for surgical treatment of arterial aneurysms, including those related to BD, although the therapy of choice is still controversial.

ABSTRACT

Abstract Internal thoracic artery aneurysms (ITAAs) are rare with wide variation in clinical presentation and a high risk of rupture. Endovascular techniques are increasingly being used for treatment of such aneurysms over surgical repair in recent times. A 34-year-old male presented with progressive swelling of the right anterior chest wall for 2 weeks and was diagnosed with right internal thoracic artery aneurysm with contained rupture. He underwent successful endovascular repair with coil embolization of ruptured right ITAA. Post intervention computed tomography (CT) angiography confirmed sealing of the ruptured aneurysm with no residual filling of the sac. At six months follow-up he is doing well with complete resolution of hematoma. This case demonstrates that an endovascular approach with coil embolization is a feasible and safe option for treating the rare ruptured ITAAs.


Resumo Os aneurismas da artéria torácica interna (ITAAs) são raros, com ampla variação na apresentação clínica e alto risco de ruptura. As técnicas endovasculares têm sido cada vez mais utilizadas para o tratamento desses aneurismas em relação ao reparo cirúrgico. Um homem de 34 anos de idade apresentou edema progressivo da parede torácica anterior direita por 2 semanas e foi diagnosticado com aneurisma da artéria mamária interna direita com ruptura contida. Ele foi submetido a reparo endovascular bem-sucedido, com embolização de ITAA direito roto. A angiotomografia computadorizada (angioTC) pós-intervenção confirmou o selamento do aneurisma rompido, sem enchimento residual do saco. No seguimento de 6 meses, ele estava bem, com resolução completa do hematoma. Este caso demonstra que a abordagem endovascular com embolização com molas é uma opção viável e segura no tratamento dos raros ITAAs rotos.

ABSTRACT

Resumo A dissecção da artéria mesentérica superior é uma causa rara de dor abdominal, com quadro clínico variável. Seu diagnóstico é difícil, e não existe consenso sobre suas opções terapêuticas; elas variam em torno de tratamento conservador, correção aberta, endovascular ou combinada. Descrevemos o caso de um homem de 45 anos com dissecção isolada da artéria mesentérica superior, com quadro de dor abdominal persistente após tentativa de tratamento conservador. Ele foi submetido à revascularização cirúrgica aberta devido à localização e complexidade da dissecção. O tratamento com endarterectomia, arterioplastia com remendo de pericárdio bovino e acesso retrógrado para abertura da mesentérica com stent foi realizado com sucesso. A angina abdominal foi totalmente resolvida após estabilização do quadro. A combinação de abordagem aberta e endovascular deve ser considerada como terapia para casos de dissecção complexa isolada da artéria mesentérica superior.


Abstract Dissection of the superior mesenteric artery is a rare cause of abdominal pain, with a variable clinical picture. It is difficult to diagnose and there is no consensus on treatment options, which range from conservative treatment to open, endovascular, or combination repair. We describe the case of a 45-year-old man with isolated dissection of the superior mesenteric artery and persistent abdominal pain after conservative treatment had been attempted. He underwent open surgical revascularization due to the location and complexity of the dissection. Treatment consisting of endarterectomy, arterioplasty with bovine pericardium patch, and retrograde access to open the mesenteric artery with a stent was successful. Abdominal angina was completely resolved after the condition had stabilized. A combination of open and endovascular approaches should be considered as treatment for cases of isolated complex dissection of the superior mesenteric artery.

ABSTRACT

Resumo A artéria femoral profunda, devido às suas características anatômicas, se encontra protegida da maioria dos traumatismos vasculares. Relatamos um caso de pseudoaneurisma de ramo perfurante da artéria femoral profunda, associado à fístula arteriovenosa, secundário a rotura completa do músculo vasto medial em paciente jogador de futebol. A ressonância magnética demonstrou lesão muscular associada a pseudoaneurisma, e a angiotomografia confirmou a presença de pseudoaneurisma associado a fístula arteriovenosa de ramo da artéria femoral profunda. Foi realizado tratamento endovascular da fístula através da embolização com micromolas fibradas e drenagem cirúrgica do hematoma muscular. O paciente evoluiu bem, sem queixas clínicas no 30º dia de pós-operatório e também após 1 ano.


Abstract Due to its anatomical characteristics, the deep femoral artery is protected from most vascular injuries. We report a case of a soccer player with pseudoaneurysm of a perforating branch of the deep femoral artery, associated with an arteriovenous fistula and secondary to complete rupture of the vastus medialis muscle. Magnetic resonance imaging showed muscle damage associated with a pseudoaneurysm and angiotomography confirmed the presence of a pseudoaneurysm associated with a deep arteriovenous fistula of a branch of the deep femoral artery. Endovascular treatment of the fistula was performed by embolization with fibrous microcoils and surgical drainage of the muscle hematoma. The patient recovered well, was free from clinical complaints on the 30th postoperative day and also after 1 year.

ABSTRACT

OBJECTIVE@#To compare the clinical effect of microsurgery and endovascular embolization in the treatment of spinal dural arteriovenous fistula (SDAVF) by meta-analysis.@*METHODS@#A systematic review was performed to retrieve all relevant literature about surgical treatment or endovascular embolization of SDAVF up to December 2019 through PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials Results, CNKI, Wanfang Data, and SinoMed. The Chinese and English key words included: "SDAVF", "spinal dural arteriovenous fistula", "spinal AVM", "spinal vascular malformation and treatment". The included studies were evaluated using the Newcastle-Ottawa scale. The early failure rate, long-term recurrence, neurological recovery, and complications were evaluated and the clinical effects of the two methods in the treatment of SDAVF were compared by using RevMan 5.3 software. And a further subgroup analysis of the therapeutic effect of endovascular embolization with different embolic agents was conducted.@*RESULTS@#A total of 46 studies involving 1 958 cases of SDAVF were included, in which 935 cases were treated by microsurgery and 1 023 cases were treated by endovascular embolization. The funnel plot demonstrated that there was no publication bias. The results of meta-analysis showed that the incidence of early surgical failure was lower than that of endovascular embolization (OR=0.20, 95%CI: 0.13-0.30, P < 0.05), and the long-term recurrence was also lower than that of endovascular embolization (OR=0.36, 95%CI: 0.22-0.58, P < 0.05). The improvement of neurological function in the surgical patients is significantly higher than that in the patients treated with endovascular embolization (OR=2.86, 95%CI: 1.36-5.99, P < 0.05). There was no significant difference in the occurrence of complications in these two groups (OR=1.52, 95%CI: 0.88-2.64, P=0.14). In the cases of endovascular embolization, the risk of treatment failure or recurrence was higher with Onyx glue than with n-butyl 2-cyanoacrylate (NBCA), and the difference was statistically significant (OR=4.70, 95%CI: 1.55-14.28, P < 0.05).@*CONCLUSION@#Although the treatment of dural arteriovenous fistulas by intravascular embolization has been widely used, the clinical effect of microsurgery is still better than that of endovascular embolization. Large scale and high-quality randomized controlled trials are required to validate the efficacy and safety of endovascular treatment in SDAVF patients.

ABSTRACT

OBJECTIVE@#Thoracoabdominal aortic aneurysm is one of the most challenging aortic diseases. Open surgical repair remains constrained with considerable perioperative morbidity and mortality. The emergence of a hybrid approach utilizing visceral debranching with endovascular aneurysm repair has brought an alternative for high-risk patients. This study aimed to compare the short- and long-term outcomes between hybrid and open repairs in the treatment of thoracoabdominal aortic aneurysms.@*METHODS@#In this retrospectively observational study, patients with thoracoabdominal aortic aneurysm treated in a single center between January 2008 and December 2019 were reviewed, of whom 11 patients with hybrid repair, and 18 patients with open repair were identified. Demographic characteristic, operative data, perioperative morbidity and mortality, freedom from reintervention, and long-term survival were compared between the two groups.@*RESULTS@#In the hybrid repair group, the patients with dissection aneurysm, preoperative combined renal insufficiency, and American Society of Anesthesiologists (ASA) score of 3 or more were significantly overwhelming than in the open repair group. The operation time of debranching hybrid repair was (445±85) min, and the intraoperative blood loss was (955±599) mL. There were 2 cases of complications in the early 30 days after surgery, without paraplegia, and 1 case died. The 30-day complication rate was 18.2%, and the 30-day mortality was 9.1%. The operation time of the patients with open repair was (560±245) min, and the intraoperative blood loss was (6 100±4 536) mL. Twelve patients had complications in the early 30 days after surgery, including 1 paraplegia and 4 deaths within 30 days. The 30-day complication rate was 66.7%, and the 30-day mortality was 22.2%. The bleeding volume in hybrid repair was significantly reduced compared with open repair (P < 0.001). Besides, the incidence of 30-day complications in hybrid surgery was significantly reduced (P=0.011). During the follow-up period, there were 4 reinterventions and 3 deaths in hybrid repair group. The 1-year, 5-year, and 10-year all-cause survival rates were 72%, 54%, and 29%, respectively. In open repair group, reintervention was performed in 1 case and 5 cases died, and the 1-year, 5-year, and 10-year all-cause survival rates were 81%, 71%, and 35%, respectively. There was no significant difference between hybrid repair and open repair in all-cause survival and aneurysm-specific survival.@*CONCLUSION@#Hybrid approach utilizing visceral debranching with endovascular aneurysm repair is a safe and effective surgical method for high-risk patients with thoracoabdominal aortic aneurysms. The incidence of early postoperative complications and mortality is significantly reduced compared with traditional surgery, but the efficacy in the medium and long term still needs to be improved.

ABSTRACT

Aortoiliac occlusive disease (AIOD) refers to the stenosis and occlusion of the distal abdominal aorta and(or) bifurcation of the aortoiliac artery,which is mainly caused by atherosclerosis,leading to pelvic and lower limb ischemia.Open surgery has always been the main treatment for complex AIOD.However,in recent years,with the development of endovascular surgery technologies and medical instruments,its treatment concept has been greatly changed.More and more clinical evidence has proved that the long-term efficacy of endovascular therapy is not inferior to that of traditional open surgery,so minimally invasive endovascular therapy has become the preferred treatment for AIOD.

ABSTRACT

Resumen La isquemia crónica con amenaza para las extremidades inferiores (ICAEI) representa el estadio final de la enfermedad arterial periférica, un problema de prevalencia creciente que conlleva el aumento de los costos de salud en todo el mundo. La ICAEI es una enfermedad con elevada morbilidad, generando mortalidad significativa, pérdida de miembros, dolor y disminución de la calidad de vida. La principal causa de amputaciones no-traumáticas de miembros inferiores está relacionada a la diabetes y a la ICAEI. Entre un 2% y 3% de los pacientes con enfermedad arterial periférica se presentan con un caso grave de ICAEI, condición que se correlaciona con enfermedad arterial multinivel y multiarterial, calcificación y oclusiones totales crónicas. Se describieron varias estrategias técnicas para cruzar con éxito largas oclusiones en segmentos arteriales. Se puede realizar la recanalización utilizando técnicas endoluminales, subintimales y retrógradas. Relatamos un caso de revascularización endovascular compleja multinivel y multiarterial a través de un bypass fémoro-poplíteo en una paciente con ICAEI.


Abstract Chronic limb-threatening ischemia (CLTI) represents the end stage of peripheral artery disease, a problem of growing prevalence and increased health care costs around the globe. CLTI is a highly morbid disease, incurring significant mortality, limb loss, pain, and diminished health-related quality of life. The major cause of non-traumatic lower extremity amputation are related to diabetes and CLTI. Between 2% to 3% of patients with peripheral artery disease present with a severe case of CLTI, a condition that is correlated with multilevel and multivessel arterial disease, calcification, and chronic total occlusions. Multiple technical strategies to successfully cross long occlusions in arterial segments have been described. Recanalization can be performed using endoluminal, subintimal, and retrograde techniques. We report a case of complex multilevel and multivessel endovascular revascularization through an occluded femoro-popliteal bypass in a patient with CLTI.

ABSTRACT

Introducción: las HSA representan el 3-5% de los ACV, siendo una patología de alto impacto en la sociedad, por su elevada morbi-mortalidad. El 80 a 85% de las HSA se deben a rotura de un aneurisma y su incidencia varía según la región entre 6 casos/100.000 habitantes-año en países como China y 22 casos/100.000 habitantes-año en países como Finlandia y Japón. Objetivo: estimar la incidencia de la HSAea en Uruguay y describir sus principales características epidemiológicas. Métodos: fueron incluidos en el estudio todos los pacientes mayores de 18 años con diagnóstico de HSAea, que consultaron en algún centro asistencial del país entre el 01/11/2019 y el 31/10/2020. Fueron relevadas las características clínicoepidemiológicas y comorbilidades al momento del diagnóstico, el tipo de tratamiento recibido y variables de evolución clínica durante los siguientes 6 meses. El análisis estadístico de los datos se basó en el cálculo de la incidencia acumulada en el período evaluado, descripción de las variables estudiadas y en la identificación de factores predictores de mala evolución clínica. Debido al carácter multicéntrico y nacional del estudio, debió ser sometido a evaluación por todos los CEI de las instituciones de salud participantes, por la CNEI y por el MSP. Resultados: se observó un total de 211 casos incidentes en el período evaluado. La media de edad fue de 57 años con predominancia del sexo femenino (75%). La tasa de incidencia fue de 8,4 nuevos casos de HSAea cada 100,000 habitantes-año. En el 24 % de los pacientes se constató que el diagnóstico inicial estuvo mal planteado (error diagnóstico). En el 82% de los casos, el estudio vascular utilizado fue la angio-TC. La topografía aneurismática más frecuente fue: arteria comunicante anterior (27,5%), arteria cerebral media (27%), y arteria comunicante posterior (23%). Un 27% tuvieron aneurismas múltiples. En el 74% de los casos fue indicado algún tipo de tratamiento específico (43% cirugía abierta y 31% terapia endovascular), mientras al resto de los pacientes no se les pudo tratar el aneurisma por su grave situación neurológica. Hubo un 25% de complicaciones vinculadas al tratamiento recibido, observándose una mayor proporción de éstas en el caso de la cirugía abierta respecto a la terapia endovascular (42% vs. 27%; p=0,006). La complicación más frecuente por la HSA fue la HCF aguda constatada en el 64% de los casos, seguida del vasoespasmo en un 38%. De las complicaciones de la HSAea vinculadas a un eventual error diagnóstico, se pudo evidenciar el vasosespasmo como único candidato. La mortalidad a los 6 meses del diagnóstico fue del 54,5%, identificándose las siguientes condiciones como predictoras independientes de un mayor riesgo de mortalidad: presencia de HSA grave desde el inicio del cuadro (HyH y WFNS 4-5), presencia de aneurismas de tipo disecante o fusiforme vs sacular, la presencia de cuello ancho o ausencia de cuello en la relación cuello-fondo del aneurisma vs cuello chico, y una edad mayor de 60 años al momento del diagnóstico. Conclusiones: Este trabajo aporta las primeras cifras sobre incidencia anual de la HSAea en el Uruguay, siendo ésta comparable a lo descrito en la literatura internacional Por otra parte, y si bien se trata de una afección grave, la sobrevida y pronóstico a corto plazo de los pacientes en nuestro país está en el límite superior de lo reportado en otras regiones del mundo

ABSTRACT

Objective To report three cases of vein of Galen aneurysmalmalformation (VGAM) in pediatric patients treated at the hemodynamics lab of Hospital Santa Isabel (HSI) in Blumenau, state of Santa Catarina, Brazil, from 2006 to 2020. Clinical presentation, endovascular treatment, and postprocedure evolution to date are included. Case description Three children aged 5 to 12 months with cardiac, respiratory, or neurological damage in the neonatal stage, were referred to the neurosurgery service and diagnosed with VGAM. The three patients underwent endovascular embolization of themalformation, with different clinical evolution throughout outpatient follow-up. Conclusion Vein of Galen aneurysmal malformations are uncommon vascular abnormalities that, until the advent of endovascular embolization, were associated with high morbidity and mortality rates. Its prognosis is linked with initial clinic, early diagnosis, and timely surgical correction.

ABSTRACT

Abstract We report the case of a 41-year-old female who presented with left upper limb embolization due to primary thoracic aortic mural thrombus; this latter represented an uncommon condition with difficult diagnosis and a high rate of life-threatening complications. Upper extremities embolization is extremely rare because it usually occurs in the lower limbs. Management strategy is still controversial, and no clear guidelines indicate superiority of either conservative or invasive treatment approach to date. Our report illustrates how endovascular exclusion of thoracic aortic mural thrombus has the advantage to be a low-risk procedure that represents a definitive therapy.

ABSTRACT

ABSTRACT Background: Among patients with acute ischemic stroke with a mismatch between deficit severity and infarct volume, thrombectomy performed within a 6-24 hours time window has efficacy and safety similar to treatment within 6 hours. However, whether magnetic resonance imaging with T2 diffusion-weighted imaging (DWI) is feasible remains to be validated. Objective: To investigate prognosis among stroke patients receiving endovascular treatment (EVT) within 6 hours and 6-24 hours using non-contrasted computed tomography (NCCT) and DWI. Methods: Overall, 209 anterior-circulation ischemic stroke patients with large-vessel occlusion who underwent EVT were divided into ≤ 6 hours and 6-24 hours groups. Patients presenting symptoms within 6 hours were treated if their NIHSS score was ≥ 7 and ASPECTS score was ≥ 5, whereas those with wake-up stroke (WUS) or presenting symptoms 6-24 hours after last seen well (WUS/late-presenting stroke, LPS) were managed if their NIHSS score was ≥ 7 and ASPECTS score was ≥ 5. Results: The percentages of patients undergoing intracranial stenting and intracranial ballooning without stenting significantly differed between two groups (p < 0.001). Grades 0, 1, 2a and 2b recanalization rates did not differ between the 6 hours and 6-24 hours groups (all p > 0.05). Grade 3 recanalization rate in the 6 hours group was significantly lower than in the 6-24 hours group (p = 0.043). The 3-month Rankin Scale score did not significantly differ between the two groups (p = 0.629). Conclusions: EVT is a safe and effective treatment for patients with WUS and LPS selected through NCCT and DWI-based simple imaging.


RESUMO Antecedentes: Entre pacientes com acidente vascular cerebral isquêmico (AVCI) agudo com divergência entre gravidade do déficit e volume do infarto, a trombectomia em 6 a 24 horas tem eficácia e segurança semelhantes ao tratamento em até 6 horas. Entretanto, a viabilidade da imagem ponderada em T2 com difusão (DWI) da ressonância magnética necessita validação. Objetivo: Investigar o prognóstico de pacientes com AVCI que recebem tratamento endovascular (EVT) em até 6 horas e de 6-24 horas usando tomografia computadorizada sem contraste (NCCT) e DWI. Métodos: Duzentos e nove pacientes com AVCI de circulação anterior submetidos a EVT foram divididos em ≤ 6 horas e 6-24 horas. Pacientes com sintomas até 6 horas foram tratados se NIHSS ≥ 7 e ASPECTS ≥ 5; aqueles com AVCI ao despertar (WUS) ou com sintomas entre 6-24 horas da última vez em que foram vistos bem (WUS/AVC de fase tardia, LPS) foram tratados se NIHSS ≥ 7 e ASPECTS ≥ 5. Resultados: As porcentagens de pacientes submetidos a implante de stent intracraniano e angioplastia intracraniana sem stent diferiram entre os dois grupos (p <0,001). As taxas de recanalização 0, 1, 2a e 2b não diferiram entre 6 horas e 6-24 horas (p> 0,05). A taxa de recanalização de grau 3 no grupo 6 horas foi menor do que 6-24 horas (p = 0,043). Pontuação na Escala Rankin (3 meses) não foi diferente (p = 0,629). Conclusões: EVT é um tratamento seguro e eficaz para pacientes com WUS e LPS selecionados por meio de imagens baseadas em NCCT e DWI.
