Embolization of the Superior Rectal Arteries versus Closed Hemorrhoidectomy (Ferguson Technique) in the Treatment of Hemorrhoidal Disease: A Randomized Clinical Trial.

PURPOSE: To compare short-term and medium-term results of superior rectal artery embolization versus surgical hemorrhoidectomy in the treatment of patients with hemorrhoidal disease. MATERIAL AND METHODS: This study was a prospective randomized clinical trial following 33 patients with symptomatic hemorrhoidal disease Grades 2 and 3 who were randomly assigned to 2 different groups: the superior rectal artery embolization group (n = 15) and Ferguson closed hemorrhoidectomy surgical group (n = 14). Four patients were excluded from the analysis. Pain using the visual analog scale and the use of analgesics were evaluated 3 times daily during the first 7 days of the postoperative period. Recurrent symptoms and satisfaction with treatment were also evaluated in the subsequent first, third, sixth, and twelfth months. RESULTS: The mean pain during the first bowel movement after the procedure was 6.08 ± 4.41 in the surgery group and 0 in the embolization group (P = .001). The mean use of pain medication was higher in the surgery group (28.92 doses ± 15.78 vs 2.4 doses ± 5.21; P < .001). In the embolization group, the most prevalent preprocedural symptom was bleeding in 14 patients, with complete improvement in 12 (83.3%) patients. Mucus, skin tag, and pruritus were symptoms that showed little improvement in both groups. The frequency of symptoms (bleeding, pain, prolapse, and pruritus) was similar between the groups at 12 months (P = .691). No severe adverse events were observed in both groups. CONCLUSIONS: Despite no difference in outcomes, embolization of the superior rectal arteries for the treatment of hemorrhoidal disease showed pain levels lower than those observed after surgical treatment.

Long-term results of oversized balloon dilation for benign anastomotic biliary strictures: initial two-center experience

Abstract Objective: To describe, assess the feasibility of, and quantify the long-term patency achieved with percutaneous transhepatic biliary dilation using the anastomotic biliary stricture (ABS) oversized balloon dilation technique as a single-step procedure for the treatment of benign anastomotic biliary strictures following hepatobiliary surgery. Materials and Methods: This was a retrospective, two-center study including 16 consecutive cases of symptomatic benign biliary-enteric strictures. After assessment of the diameter of the bile duct by computed tomography or magnetic resonance imaging, the strictures were dilated with oversized balloons (40-50% larger than the bile duct diameter) and an external biliary-enteric drain was placed. After drain removal, clinical symptoms and laboratory test results were evaluated every three months, whereas follow-up magnetic resonance imaging was performed at 30 days out and follow-up computed tomography was performed at 6 and 12 months out. Results: The mean follow-up time was 31.8 ± 8.15 months. Kaplan-Meier-estimated 1-, 2-, and 3-year patency rates were 88.2%, 82.4%, and 82.4%, respectively. There was one major complication—a small dehiscence of the anastomosis—which extended the catheter dwell time. Minor complications occurred in two cases—one small perihepatic hematoma and one segmental thrombosis of the left portal branch—neither of which required further intervention. Conclusion: The single-step ABS oversized balloon dilation technique is a feasible treatment for benign anastomotic biliary-enteric strictures. The technique appears to be associated with high rates of long-term clinical success and patency.

Resumo Objetivo: Descrever o procedimento, avaliar a viabilidade e perviedade em longo prazo da dilatação biliar trans-hepática percutânea usando a técnica de dilatação por balão superdimensionado para o tratamento em uma única etapa de estenose biliar anastomótica benigna após cirurgia hepatobiliar. Materiais e Métodos: Este estudo retrospectivo de dois centros incluiu 16 casos consecutivos de estenoses bilioentéricas benignas sintomáticas. A dilatação das estenoses com superdimensionamento do balão de 40-50% foi realizada após avaliação pré-procedimento do diâmetro do ducto biliar por tomografia computadorizada ou ressonância magnética e um dreno externo foi colocado. Os sintomas clínicos e exames laboratoriais foram avaliados a cada três meses após a remoção do dreno, enquanto o acompanhamento radiológico foi realizado com ressonância magnética em 30 dias e tomografia computadorizada em 6 e 12 meses. Resultados: O tempo médio de seguimento foi de 31,8 ± 8,15 meses. As estimativas de perviedade em um, dois e três anos foram 88,2%, 82,4% e 82,4%; respectivamente. Houve uma complicação importante, com pequena deiscência da anastomose biliodigestiva, que exigiu prolongamento do tempo de permanência do dreno externo. Complicações menores ocorreram em dois casos, um pequeno hematoma peri-hepático e uma trombose segmentar do ramo portal esquerdo e nenhum deles necessitou de intervenção adicional. Conclusão: A técnica de dilatação com balão superdimensionado para o tratamento de estenoses biliares anastomóticas benignas foi viável para o tratamento de estenoses anastomóticas bilioentéricas benignas. A técnica parece estar associada a altas taxas de perviedade e de sucesso clínico no longo prazo.

Percutaneous retrieval of intravascular foreign body in children: a case series and review.

BACKGROUND: Percutaneous retrieval of intravascular foreign bodies has recently increased as a treatment option. PURPOSE: To report our single-center experience of the percutaneous retrieval of 14 intravascular embolized catheter fragments in children and to conduct a literature review. MATERIAL AND METHODS: MEDLINE databases were searched for case reports and series including children and iatrogenic catheter fragments or guidewires retrieved through percutaneous techniques. We also conducted a retrospective analysis of 14 cases from our institution over a 14-year period. A total of 27 studies were selected comprising 74 children, plus our 14 unpublished cases. Statistical analyses were performed using Microsoft Excel version 2016. RESULTS: Port catheter fragments and peripherally inserted central catheters (PICCs) were the most embolized foreign bodies and the pulmonary artery was the most common site of embolization in 44.1% of cases. Analysis of the retrieval technique demonstrated a preference for extraction through the femoral vein (81.7%) and using snare techniques (93.5%). The success rate of percutaneous retrieval was 96.6% with only 1.1% of procedure-related complications. Patients were asymptomatic in 77.2% of cases, presented septic complications in 2.3%, and no deaths were reported. Median fluoroscopy time was 10 min (range = 1.7-80 min) and median procedure length was 60 min (range = 35-208 min). CONCLUSION: Percutaneous retrieval of intravascular foreign bodies is a feasible, safe, and efficient technique in children and should be considered the preferred treatment option.

Transarterial radioembolization for liver tumors as neoadjuvant therapy: three case reports.

Transarterial radioembolization (TARE) with yttrium-90 microspheres is a palliative locoregional treatment, minimally invasive for liver tumors. The neoadjuvant aim of this treatment is still controversial, however, selected cases with lesions initially considered unresectable have been enframed as candidates for curative therapy after hepatic transarterial radioembolization. We report three cases in which the hepatic transarterial radioembolization was used as neoadjuvant therapy in an effective way, allowing posterior potentially curative therapies.

Pulmonary arteriovenous malformations: diagnostic and treatment characteristics.

OBJECTIVE: To present a case series of pulmonary arteriovenous malformations (PAVMs), describing the main clinical findings, the number/location of pulmonary vascular abnormalities, the clinical complications, and the treatment administered. METHODS: This was a retrospective observational study evaluating patients with PAVM divided into two groups: hereditary hemorrhagic telangiectasia (HHT); and idiopathic PAVM (iPAVM). RESULTS: A total of 41 patients were selected for inclusion, but only 33 had PAVMs. After clinical evaluation, 27 and 6 were diagnosed with HHT and iPAVM, respectively. In the HHT group, the mean age was 49.6 years and 88.9% were female. In that group, 4 patients had an SpO2 of < 90% and the most common clinical finding was epistaxis. In the iPAVM group, the mean age was 48.1 years and 83.3% were female. In that group, 3 patients had an SpO2 of < 90%. Computed tomographic pulmonary angiography showed that most of the PAVMs were in the lower lobes: 56.4% in the HHT group and 85.7% in the iPAVM group. Embolization was performed in 23 patients (in both groups). At this writing, 10 patients are scheduled to undergo the procedure. One of the patients who underwent embolization was subsequently referred for pulmonary resection. CONCLUSIONS: In both of the PAVM groups, there was a predominance of women and of fistulas located in the lower lobes. Few of the patients had respiratory symptoms, and most had an SpO2 > 90%. The treatment chosen for all patients was percutaneous transcatheter embolization.

RESUMO Objetivo: Apresentar uma série de casos de malformações arteriovenosas pulmonares (MAVP) e descrever os principais achados clínicos, a quantidade e localização das MAVP, as complicações clínicas e os tratamentos realizados. Métodos: Estudo retrospectivo observacional que avaliou pacientes com MAVP divididos em dois grupos: telangiectasia hemorrágica hereditária (THH) e MAVP idiopática (MAVPi). Resultados: Foram avaliados 41 pacientes, sendo 33 pacientes portadores de MAVP. Após a avaliação clínica, 27 e 6 foram diagnosticados com THH e MAVPi, respectivamente. No grupo THH a média de idade foi de 49,6 anos e 88,9% eram do sexo feminino. Desses pacientes, 4 tinham SpO2 < 90% e o achado clínico mais frequente era epistaxe. No grupo MAVPi a média de idade foi de 48,1 anos, sendo que 83,3% eram do sexo feminino. Desses, 3 tinham SpO2 < 90%. Após a realização de angiotomografia de tórax observou-se que a maior parte das MAVP se situava nos lobos inferiores, totalizando 56,4% e 85,7% nos grupos THH e MAVPi, respectivamente. O tratamento por embolização foi realizado em 23 pacientes nos dois grupos, enquanto 10 aguardavam o procedimento até o momento da escrita deste estudo. Um paciente submetido à embolização foi encaminhado para ressecção pulmonar. Conclusões: Em ambos os grupos de pacientes com MAVP observou-se uma predominância de mulheres e de fístulas localizadas nos lobos inferiores. A maioria era assintomático respiratório com SpO2 > 90%. O tratamento de escolha para todos foi a embolização percutânea por cateter.

Aspects of images in magnetic resonance of liver tumors treated with transarterial selective internal radiotherapy with yttrium-90.

Transarterial selective internal radiation therapy with yttrium-90, also known as radioembolization, is a therapy based on the administration of resin or glass microspheres loaded with the radioisotope yttrium-90, via selective arterial catheterization of tumor-feeding vessels. It is classified as a type of locoregional therapy and its main goal is to treat patients with primary or secondary hepatic lesions that are unresectable and not responsive to other therapies. Since it is a new technology still restricted to very few hospitals in Brazil, but used in patients throughout the country, it is necessary to demonstrate the main aspects of hepatic lesions treated with selective internal radiation therapy found in magnetic resonance imaging, and to make specific considerations on interpretation of these images. The objective of this report is to demonstrate the main aspects of magnetic resonance imaging of unresectable primary or secondary hepatic lesions, in patients submitted to transarterial selective internal radiation therapy.

RESUMO A radioterapia interna seletiva transarterial com ítrio-90, também conhecida como radioembolização, é uma terapia baseada na administração de microesferas de resina ou vidro carregadas com o radioisótopo ítrio-90, via cateterismo arterial seletivo dos vasos nutridores do tumor. É classificada como um tipo de terapia locorregional e seu principal objetivo é tratar pacientes portadores de lesões hepáticas primárias ou secundárias irressecáveis e não responsivas a outras terapias. Por se tratar de uma nova tecnologia, portanto ainda restrita a pouquíssimos hospitais no Brasil (ainda que utilizada em todo país), é necessário demonstrar os principais aspectos de imagem das lesões hepáticas tratadas com radioterapia interna seletiva transarterial encontrados em exame de ressonância magnética, além de delinear considerações específicas de interpretação destas imagens. O objetivo deste relato é demonstrar os principais aspectos encontrados em ressonância magnética de lesões hepáticas irressecáveis, primárias ou secundárias, de pacientes submetidos à radioterapia interna seletiva transarterial.

Embolização seletiva das artérias prostáticas no tratamento da hiperplasia protática benigna / Selective arterial prostatic embolization to treat benign prostatic hyperplasia

Hiperplasia prostática benigna (HPB) é considerada a neoplasia masculina mais comum, além de ser a principal causa de sintomas do trato urinário baixo (STUB) em homens idosos. Se não tratada ou mal tratada, poderá levar o paciente a quadro de retenção urinária aguda, incontinência e infecção do trato urinário, progredindo em gravidade com a idade. Apesar do desenvolvimento de técnicas alternativas, a ressecção transuretral da próstata (RTU) continua sendo considerada o tratamento cirúrgico padrão ouro para HPB. Não obstante, a RTU pode estar associada a muitas comorbidades como, sangramento, sintomas urinários irritativos, disfunção sexual e ejaculação retrógrada. Por essa razão, o desenvolvimento de modalidades de tratamentos minimamente invasivos para o tratamento de HPB constitui um campo interessante de pesquisa clínica. Os objetivos deste estudo foram: (1) avaliar a viabilidade, a segurança e a eficácia da embolização das artérias prostáticas (EAP) nos pacientes com retenção urinária devido à HPB, (2) avaliar a porcentagem de redução volumétrica da próstata e a qualidade de vida após a EAP nos pacientes com retenção urinária devido à HPB. No presente estudo, Fase I prospective centro único, 11 pacientes portadores de retenção urinária devido à HPB foram tratados por meio da EAP entre agosto de 2009 e novembro de 2011. Exame físico, questionários de sintomas e qualidade de vida (International Prostate Symptom Score (IPSS) e Quality of Life (QoL)), dosagem do antígeno prostático específico (PSA), exames de imagens de ultrassom (US) e ressonância magnética (RM), e estudos urodinâmicos foram realizados antes e 1, 3, 6, e 12 meses depois da EAP. O tamanho da próstata variou de 30 a 90 gramas, e as embolizações foram realizadas com microesferas (Embospheres) de 300-500?m. O sucesso técnico (EAP bilateral) foi atingido em 75%, e o sucesso clínico (retirada do cateter vesical de demora e melhora dos sintomas) foi obtido em 91% (10 de 11 pacientes) dos casos...

Benign prostatic hyperplasia (BPH) is considered the most common neoplasm in men and is the main cause of lower urinary tract symptoms (LUTS) in the aging male. If left untreated or not effectively treated, can lead to acute urinary retention, incontinence, and urinary tract infections, progressing in severity with age. Despite the development of alternative techniques, transurethral resection of the prostate (TURP) is still considered the gold standard surgical treatment for BPH. However, TURP procedures can be associated with substantial morbidities such as bleeding, irritative urinary symptoms, erectile dysfunction and ejaculatory disorders. For this reason, the development of minimally invasive modalities for treatment of BPH has constituted an interesting field of research. The study objectives were: (1) to evaluate the feasibility, safety and efficacy of the prostatic artery embolization (PAE) in patients with urinary retention due to BPH, (2) to evaluate the percentage of reduction in prostate volume and quality of life after PAE in patients with urinary retention due to BPH. In the present study, a single-center prospective phase I study, 11 patients with urinary retention due to BPH were treated by PAE between August 2009 and November 2011. Physical examination, International Prostate Symptom Score (IPSS) and Quality of Life (QoL), prostate specific antigen (PSA) measurement, ultrasound (US) and magnetic resonance imaging (MRI), and urodynamic tests were performed at baseline, 1, 3, 6 and 12 months after PAE. Prostate size ranged from 30 to 90g, and embolizations were performed with 300- 500-?m Embosphere microspheres. Technical success (ie, bilateral PAE) was obtained in 75%, and clinical success (ie, catheter removal and symptom improvement) was obtained in 91% (10 of 11patients) of the cases. Postembolization syndrome manifested as mild pain in the perineum, retropúbica area, and/ or urethra. No major complications were observed. At the first year...

Endovascular techniques and procedures, methods for removal of intravascular foreign bodies.

INTRODUCTION: The incidence of intravascular embolization of venous catheters reported in the world medical literature corresponds to 1% of all the described complications. However, its mortality rate may vary between 24 to 60%. Catheter malfunction is the most likely signal of embolization, since patients are usually asymptomatic. OBJECTIVE: To report the method of removing intravascular foreign bodies, catheters with the use of various endovascular techniques and procedures. METHODS: This is a two-year retrospective study of 12 patients: seven women and five men. The average age was 29 years (ranging from two months to 65 years). RESULTS: Technical performance was 100% successful. Ten port-a-caths, one intra-cath and one PICC were extracted. The most common sites for the lodging of one of the ends of the intravascular foreign bodies were the right atrium (41.6%) and the right ventricle (33.3%). In 100% of the cases, only one venous access was used for extraction of foreign bodies, and in 91.6% of the cases (11 catheters) the femoral access was used. The loop-snare was used in 10 cases (83.3%). The most common cause of intravascular foreign body insertion was a catheter fracture, which occurred in 66.6% of the cases (eight cases). One major complication, the atrial fibrillation, occurred (8.3%), which was related to the intravascular foreign body extraction. The mortality rate in 30 days was zero. CONCLUSION: Percutaneous retrieval of intravascular foreign bodies is considered gold standard treatment because it is a minimally invasive, relatively simple, safe procedure, with low complication rates compared to conventional surgical treatment.

Endovascular treatment of the middle aortic syndrome due to Takayasu's arteritis: case report

Síndrome da aorta média (SAM) é uma condição clínica caracterizada por estenose segmentar ou difusa da aorta, hipertensão arterial e claudicação de membros inferiores. A principal causa da SAM é a arterite de Takayasu. A estenose segmentar pode estar localizada na aorta suprarrenal, renal ou infrarrenal e com alta propensão de lesões estenóticas concomitantes das artérias renais e viscerais. A gravidade da hipertensão arterial é a principal indicação para o tratamento. A técnica endovascular para o tratamento da síndrome da aorta média tem bons resultados e é a menos invasiva. No presente artigo, é descrito o tratamento com sucesso de uma estenose da aorta toracoabdominal com recanalização da artéria mesentérica superior através de angioplastia em uma mulher de 34 anos portadora de arterite de Takayasu e hipertensão arterial grave.

Middle aortic syndrome (MAS) is a clinical condition characterized by segmental or diffuse narrowing of the aorta, hypertension, and lower limb claudication. The main cause of MAS is Takayasu's arteritis. Segmental aortic stenosis may be located at the suprarenal, renal or infrarenal aorta with high tendency to concomitant stenosis in both the renal and visceral arteries. Severity of hypertension is the primary indication for intervention. Endovascular therapy is a minimally invasive treatment for MAS and may provide good results. In the present report, we describe a successful endovascular treatment of stenosis of the thoracoabdominal aorta with recanalization of the superior mesenteric artery using angioplasty in a 34-year-old woman with Takaysu's arteritis and severe hypertension.

Aneurisma de artéria esplênica: relato de caso / Splenic artery aneurysm: a case report

O aneurisma de artéria esplênica é uma afecção rara e geralmente assintomática. Sua etiologia é desconhecida, porém, frequentemente está associado a inúmeras condições clínicas, como gestações multiplas, hipertenção portal e esplenomegalia, hipertensão arterial essencial, aterosclerose, colagenoses, trauma e outros. O diagnóstico frequentemente é acidental e feito através de exames de imagem. A importância do diagnóstico precoce está na elevada mortalidade nos casos de rotura. O tratamento cirúrgico eletivo está indicado em aneurismas maiores do que 2cm ou com crescimento rápido ou acompanhamento clínico, aneurismas sintomáticos ou quando associados com pancreatite e pseudocisto pancreático. No presente relato é apresentado o caso de uma paciente na qual foram indicados dois aneurismas de artéria esplênica durante a investigação de massa abdominal pulsátil. A mesma era portadora de hipertensão portal de etiologia esquistossomótica. A ulta-sonografia, a tomografia de abdome e a arteiografia seletiva da arteria esplênica contribuíram para o diagnóstico. No intra-operatório foram evidenciadas duas formações saculares aneurismática de aproximadamente 6 a 10 cm, sendo então submetida à aneurismectomia com esplenectomia e desconexão ázigo-portal
