ABSTRACT
Resumen: El aneurisma gigante de la arteria subclavia asociado a un síndrome de vena cava superior se presenta de forma poco frecuente. La complejidad del abordaje dependerá del tamaño, forma y disposición del aneurisma, particularmente cuando el colapso de la vía aérea es potencial por un efecto compresivo de la masa mediastinal durante la aplicación del relajante neuromuscular. Presentamos el caso de un hombre de 57 años con disnea en decúbito dorsal que incrementa con el decúbito lateral izquierdo de cinco años de evolución. El estudio radiológico reporta masa mediastinal gigante compatible con aneurisma de la arteria subclavia derecha que causa compresión y desplazamiento de la vía aérea, particularmente en tráquea a nivel de la carina. El paciente es programado para resección del aneurisma y requiere de intubación selectiva para el aislamiento del pulmón derecho durante la cirugía, que fue realizada con la técnica de paciente despierto usando sedoanalgesia con ketodex. El objetivo del caso es compartir la experiencia con el uso de ketodex como una alternativa para la tolerancia de procedimientos que requieren de la cooperación del paciente, en donde el propofol y el relajante neuromuscular pueden ser un problema para la permeabilidad y el abordaje de la vía aérea.
Abstract: A giant subclavian artery aneurysm associated with superior vena cava syndrome occurs infrequently. Complexity of the approach will depend on the size, shape, and position of the aneurysm, particularly when a potential collapse of the airway is expected due to the compressive effect of the mediastinal mass after using neuromuscular relaxant for airway approach. We present a case in a 57-year-old male with shortness of breath in dorsal that increases with left lateral decubitus during five years of evolution. Radiological studies reported giant mediastinal mass compatible with an aneurysm of the right subclavian artery, which produces critical compression and airway displacement, particularly in trachea at level of the carina. The patient is scheduled for resection of the aneurysm and requires selective intubation for isolation of the right lung during surgery which was performed with the awake patient technique using sedoanalgesia with ketodex. The objective of the case is to share the experience using ketodex as an alternative for the tolerance of procedures that requires the cooperation of the patient where propofol and neuromuscular relaxant may be a problem for airway permeability and approach.
ABSTRACT
SUMMARY: An aberrant right subclavian artery described by David Bayford, is rare and one of the aortic arch anomalies. It gives usually incidental findings. We present the case of a 57-year-old woman who was admitted to a neurology outpatient clinic due to a headache and no obvious pathology was detected during a physical examination. In consequence of the brain and chest CT angiography, incidental anomalies of the aortic arch branches were found and asymptomatic aberrant right subclavian artery and bicarotid trunk was diagnosed. The presence of this anomaly is becoming increasingly important in avoiding vascular injuries and cerebral complications in patients undergoing endovascular intervention on the aorta aortic arch surgery, thyroidectomy, or cervicothoracic surgery. So, detailed knowledge of variations of the subclavian artery and bicarotid trunk is paramount for radiologists and surgeons operating on the region of the anterior neck.
Una arteria subclavia derecha aberrante descrita por David Bayford, es rara y es una de las anomalías del arco aórtico. Además, suele ser hallazgos accidentales. Presentamos el caso de una mujer de 57 años que ingresó a una consulta de neurología por dolor de cabeza, sin embargo, no se le detectó patología evidente al examen físico. En el angio-TC de cerebro y tórax, se encontraron anomalías incidentales de las ramas del arco aórtico y se diagnosticó arteria subclavia derecha aberrante asintomática y tronco bicarotídeo. Determinar la presencia de esta anomalía es cada vez más importante, para así evitar lesiones vasculares y complicaciones cerebrales en pacientes sometidos a intervención endovascular de la aorta, cirugía del arco aórtico, tiroidectomía o cirugía cervicotorácica. Por lo tanto, el conocimiento detallado de las variaciones de la arteria subclavia y el tronco bicarotídeo es primordial para los radiólogos y cirujanos que operan en la región anterior del cuello.

A 52-year-old man presented himself to his family doctor for uremia associated with prerenal acute renal failure. A 12 Fr vascular access catheter was inserted via the right internal jugular vein for emergency dialysis. A contrast-enhanced computed tomography (CT) scan revealed that the catheter had penetrated the right internal jugular vein, perforated the right subclavian artery, and reached the ascending aorta. Under general anesthesia, we completed the procedure with a pull-through technique between the bilateral brachial arteries. A vascular occlusion balloon was inserted from the left brachial artery and a GORE VIABAHN stent graft was inserted from the right brachial artery. The postoperative course was good and he has been free from hemorrhagic episodes. He was transferred to the referring hospital on postoperative day 2.
ABSTRACT
We report a case of surgery for an infectious left subclavian artery aneurysm in a patient with metal allergy. The patient was a 41-year-old man allergic to iron, silver, manganese, and chromium. He had received a Nitinol stent in the left subclavian artery at a previous hospital. One stent had fallen out during implantation, and was put away in the terminal aorta. Ten days after the left subclavian implantation, the patient developed left shoulder pain and fever, which continued for 2 weeks. Contrastenhanced CT scan revealed a pseudoaneurysm of the left subclavian artery and abdominal aortitis. The patient underwent left subclavian artery aneurysmectomy, aorto-left subclavian artery bypass using the great saphenous vein, and removal of the stents in the left subclavian artery and abdominal aorta. The surgery was performed through a median sternotomy with cardiopulmonary support. A contrast-enhanced CT scan taken on the 12th postoperative day revealed a pseudoaneurysm of the abdominal aorta, and the patient underwent abdominal aortic artery replacement surgery on the 14th postoperative day. The patient was discharged from the hospital on the 27th day after the first surgery. The treatment of an aneurysm should be selected according to the patient’s background as well as anatomical factors.
ABSTRACT
@#Objective To investigate the effect of in vitro fenestration on reconstruction of left subclavian artery in endovascular treatment of aortic dissection. Methods A total of 89 patients with aortic dissection involving left subclavian artery were treated by endovascular treatment in the Second Affiliated Hospital of Fujian Medical University from February 2017 to January 2020. There were 44 patients in the test group, including 36 males and 8 females, with an average age of 58.02±13.58 years. There were 45 patients in the control group, including 35 males and 10 females, with an average age of 54.10±12.32 years. The left subclavian artery was reconstructed by in vitro fenestration in the test group and by chimney technique in the control group. The clinical data were compared between the two groups. Results The operation time of the test group was longer than that of the control group (126.16±7.53 min vs. 96.49±6.52 min, P<0.01). The median follow-up time was 31 (13-48) months. The incidence of endoleak in the test group (4.7%) was lower than that in the control group (18.6%, P=0.04) during the follow-up. There was no statistical difference in the incidence of stroke, myocardial infarction, false lumen thrombosis, retrograde aortic dissection or left subclavian artery occlusion between the two groups (P>0.05). Conclusion In vitro fenestration for reconstructing left subclavian artery in thoracic endovascular aortic repair of aortic dissection is safe and feasible, which is worthy of further clinical promotion.
ABSTRACT
Objective:To summarize our experience and outcomes of surgical repair of type Ⅱ right-sided aortic arch(RAA) with Kommerell's diverticulum(KD).Methods:From May 2010 to August 2020, a total of 13 patients with type Ⅱ RAA and KD underwent surgery at our center. Mean age was(50.46±10.31) years, 10 were male, and 3 were female. All patients had an aneurysmal KD and aberrant left subclavian artery(ALSA). Preoperative comorbidities included type B aortic dissection in 1 case, aortic arch pseudoaneurysm in 2 cases, and type B intramural hematoma in 2 cases, respectively. Eight(61.5%) patients underwent stented elephant trunk procedures under moderate hypothermic circulatory arrest combined with selective antegrade cerebral perfusion via median sternotomy, and all of them had ALSA reconstruction. Five(38.5%) patients underwent distal arch and descending thoracic aortic replacement through a right posterolateral thoracotomy, the ALSA was reconstructed or ligated in 1 each, and ALSA embolization was performed before surgery in the other 3 cases.Results:No operation deaths occurred. Recurrent laryngeal nerve injury occurred in 2 cases. There was 1(7.69%) in-hospital death. Follow-up was complete in 100 % at mean(5.28±3.84) years. No late death occurred. A persistent anastomotic leak of the proximal arch was detected in a patient who underwent stented elephant trunk procedure, but no aortic dilatation or tracheal and esophageal compression was observed during follow-up. Meanwhile, aortic events, limb ischemia, or symptoms of tracheal and esophageal compression were not observed in the remaining 11 patients.Conclusion:Surgical repair of type Ⅱ RAA with KD can achieve favorable early and midterm outcomes. Surgical strategies should be chosen based on the anatomy of the aorta and whether it is combined with compression symptoms.
ABSTRACT
@#Objective To investigate the consistency of carotid Doppler ultrasonography (CDU), computed tomography angiography (CTA), and digital subtraction angiography (DSA) in the diagnosis of subclavian artery stenosis, as well as the hemodynamic parameters for different degrees of subclavian artery stenosis with DSA as the gold standard. Methods A retrospective analysis was performed for 179 patients who were admitted to Stroke Center of The First Affiliated Hospital of Soochow University from January 2018 to December 2021. CDU, CTA, and DSA were performed within one week, and at least one examination suggested subclavian artery stenosis. The 179 patients were analyzed in terms of the degree of subclavian artery stenosis at both sides. DSA was used as the gold standard to evaluate the degree of subclavian artery stenosis diagnosed by CDU and CTA, and the Kappa consistency analysis was performed for CDU and CTA in evaluating the degree of stenosis. DSA was used as the gold standard for the classification of stenosis degree, and the ROC curve analysis was used to determine the optimal cut-off values of blood flow velocity [peak systolic velocity (PSV) and end-diastolic velocity (EDV)] and blood flow velocity ratio (PSVOR/PSVDIS) in mild stenosis (< 50%), moderate stenosis (50% ~ 69%), and severe stenosis (70%~99%). Results The Kappa consistency analysis showed that CTA had a high consistency with DSA (κ=0.777), and CDU had a good consistency with DSA (κ=0.813). With DSA as the standard, the cut-off values of PSV, EDV, and PSVOR/PSVDIS based on CDU were PSV<252 cm/s, EDV<21 cm/s, and PSVOR/PSVDIS<1.9 in the diagnosis of mild stenosis, 252 cm/s≤PSV<339 cm/s, 21 cm/s≤EDV<39 cm/s, and 1.9≤PSVOR/PSVDIS<4.0 in the diagnosis of moderate stenosis, and PSV≥ 339 cm/s, EDV≥39 cm/s, and PSVOR/PSVDIS≥4.0 in the diagnosis of severe stenosis. Conclusion CDU can evaluate the degree of subclavian artery stenosis and hemodynamic changes in a noninvasive, real-time, and dynamic manner and provide a basis for the hierarchical management of clinical precision treatment.
ABSTRACT
Resumo A artéria subclávia direita aberrante, também conhecida como artéria lusória, é a anomalia do arco aórtico mais comum, ocorrendo entre 0,5 e 1% da população. Possui prevalência em mulheres e normalmente está associada a outras variações anatômicas, como o nervo laríngeo não recorrente, presente em 86,7% dos casos. Em sua maioria, a artéria subclávia direita aberrante não apresenta sintomas. Descrevemos essa alteração em uma paciente de 82 anos, hipertensa e assintomática, que havia sido submetida a uma angiotomografia toracoabdominal para a avaliação de uma dissecção crônica tipo III (DeBakey) associada à dilatação de aorta descendente. No achado, a artéria subclávia direita aberrante apresentava percurso retroesofágico associado a um divertículo de Kommerell. Devido à raridade, realizamos revisão bibliográfica integrativa das bases de dados MEDLINE, UpToDate, LILACS, SciELO e Portal CAPES dos últimos 6 anos e discutimos as alterações anatômicas mais frequentes, a sintomatologia e as condutas terapêuticas adotadas.
Abstract The aberrant right subclavian artery, also known as the arteria lusoria, is the most common aortic arch anomaly, occurring in 0.5 to 1% of the population. There is a higher prevalence in women and it is usually associated with other anatomical variations, such as the non-recurrent laryngeal nerve, present in 86.7% of cases. In the majority of cases, the aberrant right subclavian artery causes no symptoms. We describe this anomaly in an 82-year-old, hypertensive, and asymptomatic patient who had undergone a thoracoabdominal angiography to investigate a chronic DeBakey type III aortic dissection with dilation of the descending aorta. The aberrant right subclavian artery followed a retroesophageal course and was associated with a Kommerell diverticulum. In view of its rarity, we conducted an integrative bibliographic review of literature from the last 6 years indexed on the Medline, UpToDate, Lilacs, Scielo, and Portal Capes databases and discuss the most frequent anatomical changes, symptomatology, and therapeutic management adopted.
ABSTRACT
Abstract The subclavian artery is a significant branch of the aortic arch. We present a rare case of a bilateral variation in the branching pattern of the subclavian artery, observed in an adult male cadaver aged 70 years. On both the sides of the neck, all the branches of the subclavian artery took their origin from its first part. There was a rare occurrence of a cervicodorsoscapular trunk, which gave rise to superficial cervical, suprascapular, and dorsal scapular arteries. The same branching pattern was observed on the left side of the neck, with the presence of another cervicodorsoscapular trunk. Thyrocervical trunk and transverse cervical artery were both absent from the cervical region bilaterally. The inferior thyroid artery was a direct branch from the subclavian artery. Knowledge regarding variations of the subclavian artery is very important as lateral cervical region arteries are important for flap harvesting in plastic and reconstruction surgery. Preoperative radiologic evaluation of pedicles might help in choosing the optimal flap design, prevent ischemic complications, and help to improve overall treatment outcomes.
Resumo A artéria subclávia é um ramo significativo do arco da aorta. Apresentamos um caso raro de variação bilateral do padrão de ramificação da artéria subclávia, observada em um cadáver adulto do sexo masculino de 70 anos. Em ambos os lados do pescoço, todos os ramos da artéria subclávia originavam-se de sua primeira parte. Houve rara ocorrência de tronco escapular cervical dorsal, que deu origem às artérias cervical superficial, supraescapular e escapular dorsal. O mesmo padrão de ramificação foi observado no lado esquerdo do pescoço, com a presença de tronco escapular cervical dorsal. O tronco tireocervical e a artéria cervical transversa estavam ausentes em ambas as regiões cervicais direita e esquerda. A artéria tireóidea inferior consistia em um ramo direto da artéria subclávia. O conhecimento das variações da artéria subclávia é fundamental, pois as artérias da região cervical lateral são importantes para a obtenção de retalhos em cirurgias plásticas e reconstrutivas. A avaliação radiológica pré-operatória dos pedículos pode ajudar na escolha do desenho ideal do retalho, prevenir complicações isquêmicas e ajudar a melhorar o resultado geral do tratamento.
ABSTRACT
Case 1 is a 70-year-old male. He has a history of cholelithiasis and left inguinal hernia. A preoperative examination of the inguinal hernia showed the enlargement of the mediastinal shadow, and he was referred to our department. A close examination revealed a right-sided aortic arch, a right descending aorta, and a descending aortic diverticulum. No subjective symptoms, intracardiac malformations, or other cardiovascular diseases were observed. The surgery was scheduled for descending aorta replacement including a diverticulum with right posterior lateral 4th intercostal thoracotomy and lower body partial extracorporeal circulation. However, due to aortic intima injury at the proximal end, hypothermic cerebral circulatory arrest and proximal anastomosis were performed by the open proximal method. There was no problem with the postoperative course, and he was discharged 19 days after surgery. Case 2 is a 51-year-old female. Born in China, she has lived in Japan for 15 years. No notable history. An abnormal shadow was shown on chest Xp performed in a medical examination, and aortic malformation was suspected on chest CT. She was referred to our department. The diagnosis was right-sided aortic arch, right descending aorta, aberrant left subclavian artery, and Kommerell diverticulum. There were no subjective symptoms and no intracardiac malformations. The operation was a two-stage operation. As the initial surgery, median sternotomy was performed, total arch replacement with intrathoracic reconstruction of the left subclavian artery, and open stent graft insertion, and the Kommerell diverticulum was covered with an open stent graft. We did not treat the diverticulum because it was located on the dorsal side. At 15 days after surgery, we performed embolization of the origin of the left subclavian artery from the Kommerell diverticulum. There was no problem with the postoperative course, and she was discharged 19 days after the initial surgery.
ABSTRACT
We report a case of debranching thoracic endovascular aortic repair for Kommerell's diverticulum with right-sided aortic arch in 78-year-old women. The computed tomography (CT) demonstrated Kommerell's diverticulum with a right-sided aortic arch and the trachea and esophagus were compressed by the diverticulum. The diverticulum had a maximum diameter of 32 mm, and surgical intervention was chosen because of the aneurysmal change and the possibility of rupture. We performed endovascular aortic repair for Kommerell's diverticulum with a right-sided aortic arch because of low lung function and low frailty. The patient was discharged on the 21st postoperative day. There was no evidence of aortic event during 2 years follow up.
ABSTRACT
ABSTRACT Introduction: In this study, we aimed to present three different methods for symptomatic aberrant right subclavian artery (ARSA) surgery. Methods: We identified 11 consecutive adult patients undergoing symptomatic and/or aneurysmal ARSA repair between January 2016 and December 2020. Symptoms were dysphagia (n=8) and dyspnea + dysphagia (n=3). Six patients had aneurysm formation of the ARSA (mean diameter of 4.2 cm [range 2.8 - 6.3]). All data were analyzed retrospectively. Results: Median age of the patients (7 females/4 males) was 55 years (range 49 - 62). The first four patients (36.4%) underwent hybrid repair using thoracic endovascular aortic repair (TEVAR) and bilateral carotid-subclavian artery bypass (CScBp). Three patients (27.2%) were treated by open ARSA resection/ligation with left mini posterolateral thoracotomy (LMPLT) and right CScBp. And the last four patients (36.4%) underwent ARSA resection/ligation with LMPLT and ascending aorta-right subclavian artery bypass with upper mini sternotomy (UMS). Two of the four patients who underwent TEVAR + bilateral CScBp had continuing dysphagia cause of persistent esophageal compression. Brachial plexus injury developed in one of three patients who underwent LMPLT + right CScBp. Pleural effusion treated with thoracentesis alone was observed in one of four patients who underwent UMS + LMPLT. Conclusion: Among the symptomatic and/or aneurysmal ARSA treatment approaches, surgical and hybrid methods are used. There is still no consensus on how to manage these patients. In our study, we recommend the UMS + LMPLT method, since the risk of complications with anatomical bypass is less, and we have more successful surgical results.
ABSTRACT
ABSTRACT Introduction: The aim of this study was to present the mid-term results of patients who had undergone a carotid-subclavian bypass surgery after a thoracic endovascular aortic repair (TEVAR) stent-graft implantation with proximal landing at zone 2 of the aorta. Methods: A total of 66 patients had undergone TEVAR and carotid-subclavian bypass between January 2015 and May 2020 at our clinic. Five of these patients were lost to follow-up, so 61 patients were included in this retrospective study. At follow-up visits, patency of the carotid-subclavian bypass grafts was evaluated with physical examination and radiological imaging. Results: The mean follow-up time was 15.11±12.29 months (ranging from 1 to 56 months). There were 3 (4.91%) in-hospital deaths of patients admitted with bilateral lower limb and visceral malperfusion. There were also 2 (3.27%) deaths unrelated to the procedure. Carotid-subclavian graft occlusion occurred in 3 (4.91%) patients. The occlusion was detected with radiological imaging within a period of 12 to 24 months. The graft patency rate was 100% in the first 12 months. The mean graft patency time (survival) was 52.56±2.10 months. Conclusion: Periprocedural carotid-subclavian bypass surgery with synthetic grafts is a recommended procedure with high patency and acceptably low mortality and morbidity rates in TEVAR.
ABSTRACT
Abstract Coronary subclavian steal syndrome is an uncommon cause of angina in patients with a previous coronary artery bypass graft procedure. The patient had chest pain with the exertion of the left upper limb, difference in blood pressure between the left and right arm, occlusion at the ostium of the left subclavian artery. He underwent carotid subclavian bypass surgery that was successful in relieving symptoms. On the other hand, the patient had an embolic stroke related to the procedure and further assessment may be necessary.
ABSTRACT
Subclavian steal syndrome is a relatively rare condition that results from occlusion of the subclavian artery proximal to the origin of the vertebral artery. This causes a reversal in the direction of the blood flow in the vertebral artery, leading to symptoms of vertebrobasilar insufficiency. In this article, we report a case of subclavian steal syndrome in a 55 year old male, who presented with giddiness, and variation in blood pressures in both upper limbs, was investigated with doppler and MR angiography. This article emphasises physical examination with discrepancy in pulse and blood pressure should bring attention to diagnosis of this syndrome.
ABSTRACT
Resumo Desde a primeira descrição da tetralogia de Fallot (ToF) em 1671 por Niels Stensen e em 1888 por Étienne-Louis Arthur Fallot, vários trabalhos relataram essa anomalia juntamente com suas variantes e anomalias cardiovasculares concomitantes. A artéria subclávia direita aberrante (ASDA) é a anomalia do arco aórtico mais comum. Diferentemente da artéria subclávia esquerda aberrante, a ocorrência de ASDA em pacientes com ToF só foi relatada casuisticamente. Apresentamos dois pacientes de ToF com ASDA. É importante notar que o conhecimento da coexistência das duas anomalias tem pontos muito práticos durante correções endovasculares ou cirúrgicas de defeitos cardíacos congênitos (inclusive ToF).
Abstract Since the first description of Tetralogy of Fallot (ToF) in 1671 by Niels Stensen and in 1888 by Étienne-Louis Arthur Fallot, numerous papers have reported on this anomaly, along with its variants and concomitant cardiovascular anomalies. Aberrant right subclavian artery (ARSA) is the most common anomaly of the aortic arch. Different from the left aberrant subclavian artery, occurrence of ARSA in ToF-patients has only casuistically been reported so far. The present study reports on two ToF-patients with ARSA. It is important to note that knowledge of the coexistence of both anomalies has highly practical points during surgical or endovascular corrections of congenital heart defects (including ToF).
ABSTRACT
Background: The risk of injuring recurrent laryngeal nerves which can result in voice or swallowing problems can be a major complication during thyroid surgeries. Intraoperative injury to RLN can be an issue and can have a detrimental impact on patients’ quality of life. The incidence of injury to recurrent laryngeal nerve worldwide ranges from 0.5 to 20%. To prevent such surgical complications of thyroid, a detailed anatomy of inferior vascular pedicle (inferior thyroid artery) and its relation to adjacent recurrent laryngeal nerve is required. Aim: The aim of the study was, To find out the variable anatomical relationship between inferior thyroid artery and recurrent laryngeal nerve at the base of lateral lobes of thyroid gland. Materials and methods: This descriptive study was conducted for a period of 72 months at the Department of Anatomy, Government Medical College, Omandurar Government Estate, Chennai-2, between January 2015 – January 2021 by dissection method in 60 adult (54 male and 6 female) cadavers (60 – right & 60 – left sides). Results: Results were noted, tabulated and interpreted. It was found that the recurrent laryngeal nerve at the base of thyroid gland which was predominantly posterior on both sides (R-78.33%, L- 100%) to inferior thyroid artery and in 21.66% anterior to ITA on right. Conclusion: The recurrent laryngeal nerve may lie anterior or posterior to inferior thyroid artery. In the present study, the recurrent laryngeal nerve was posterior most commonly on both sides to inferior thyroid artery. On the right, the second common presentation was the recurrent laryngeal nerve lying anterior to inferior thyroid artery.
ABSTRACT
Vascular compression of the esophagus by an aberrant right subclavian artery (aRSA) leading to dysphagia is a rare occurrence. There has been a significant advancement in the diagnostic and surgical treatment modalities available for this disorder. Anesthetic management has evolved too and this case report highlights the anesthetic management of a 41?year?old woman presenting with symptoms of dysphagia because of compression of esophagus by an aRSA, who subsequently underwent re?implantation of aRSA into ascending aorta.
ABSTRACT
Objective:To evaluate Castor single-branch covered-stent in the treatment of Stanford B aortic dissection(TBAD)with insufficient anchorage zone.Methods:Clinical data of 25 TBAD patients (proximal healthy landing zone ≤15 mm) treated with Castor branched stent-graft at Weifang People's Hospital from Apr 2019 to Sep 2021 were analyzed retrospectively.The stent model was selected according to preoperative CTA examination and intraoperative angiography,the operation result and follow up data were reviewed.Results:The operation success rate was 100%,the mean operative time was (137.8±35.8)min, and the mean blood loss was (52.8±24.5)ml. There were 2 cases of internal leakage (IA) and it was disappeared after balloon dilation, Branched stent stenosis occurred in 2 cases and relieved by balloon dilatation. The mean follow-up time was 14.6 months, and the patency rate of branch stent was 100% during the follow-up period. The true lumen diameter of thoracic aorta was significantly expanded and the false lumen diameter was significantly reduced 3 months after surgery compared with that before surgery ( P<0.05). Conclusion:Castor stenting in the treatment of TBAD with insufficient proximal anchoring area is simple and feasible, with satisfactory short term clinical effect.
ABSTRACT
Abstract Coarctation of the aorta is a rare congenital abnormality, with an incidence of 6-8% of all congenital heart problems. It is usually diagnosed in childhood during routine clinical examination and adults mostly present with hypertension. Various investigations like transthoracic echocardiography, computed tomography, and magnetic resonance angiography can help with diagnosis. Prognosis depends on age at presentation and the severity of coarctation. Treatment options available are open and endovascular repair. Extra-anatomical bypass is the preferred option in cases with unfavorable anatomy. Long term follow up is required post repair due to risk of restenosis and aneurysm formation. Here is a case in which a young female presented with hypertension, was diagnosed with coarctation of the aorta, and was treated a left subclavian artery to descending thoracic aorta bypass. Her postoperative course was uneventful and she had improvement in hypertension.
Resumo A coarctação da aorta é uma anomalia congênita rara, com incidência de 6-8% entre todos os problemas cardíacos congênitos. É geralmente diagnosticada na infância durante o exame clínico de rotina, e os adultos normalmente apresentam hipertensão. Diversas investigações, como ecocardiografia transtorácica, tomografia computadorizada e angiorressonância magnética, podem auxiliar no diagnóstico. O prognóstico depende da idade na apresentação e da gravidade da coarctação. As opções de tratamento disponíveis são o reparo aberto e o reparo endovascular. O bypass extra-anatômico é a opção preferida em caso de anatomia desfavorável. O acompanhamento de longo prazo é necessário após o reparo devido ao risco de reestenose e formação de aneurisma. Descrevemos o caso de uma jovem do sexo feminino que apresentou hipertensão, a qual foi diagnosticada como coarctação da aorta. Foi realizada derivação da artéria subclávia esquerda para a aorta torácica descendente. O pós-operatório transcorreu sem intercorrências, e a paciente apresentou melhora da hipertensão.
