Diretrizes da Sociedade Brasileira de Angiologia e Cirurgia Vascular para o tratamento da doença cerebrovascular extracraniana / Brazilian Angiology and Vascular Surgery Society Guidelines for the treatment of extracranial cerebrovascular disease

Resumo A doença cerebrovascular extracraniana tem sido intensamente investigada em todo o mundo, sendo tema de suma importância para os cirurgiões vasculares. A presente Diretriz foi elaborada pela Sociedade Brasileira de Angiologia e Cirurgia Vascular (SBACV) em sucessão à Diretriz de 2015. As doenças de etiologia não ateroscleróticas não foram incluídas nesse documento. O objetivo desta Diretriz é congregar as evidências mais robustas nessa área para auxiliar os especialistas no processo decisório do tratamento. Foi utilizada a metodologia AGREE II e o sistema da Sociedade Europeia de Cardiologia para as recomendações e níveis de evidências. As recomendações foram graduadas de I a III, e os níveis de evidência classificados em A, B e C. A presente Diretriz foi dividida em 11 capítulos, que tratam dos vários aspectos da doença cerebrovascular extracraniana: diagnóstico, tratamentos e complicações, de forma atualizada e com as recomendações propostas pela SBACV.

Abstract Extracranial cerebrovascular disease has been the subject of intense research throughout the world, and is of paramount importance for vascular surgeons. This guideline, written by the Brazilian Society of Angiology and Vascular Surgery (SBACV), supersedes the 2015 guideline. Non-atherosclerotic carotid artery diseases were not included in this document. The purpose of this guideline is to bring together the most robust evidence in this area in order to help specialists in the treatment decision-making process. The AGREE II methodology and the European Society of Cardiology system were used for recommendations and levels of evidence. The recommendations were graded from I to III, and levels of evidence were classified as A, B, or C. This guideline is divided into 11 chapters dealing with the various aspects of extracranial cerebrovascular disease: diagnosis, treatments and complications, based on up-to-date knowledge and the recommendations proposed by SBACV.

Epidemiological Analysis of 12 Years of Open Thoracoabdominal Aortic Aneurysm Repair in the Brazilian Public Health System

ABSTRACT Introduction: Although endovascular correction is a promising perspective, the gold-standard treatment for thoracoabdominal aortic aneurisms and type-B dissections with visceral involvement remains open surgery, particularly due to its well-established long-term durability. This study aims to describe and evaluate public data from patients treated for thoracoabdominal aortic aneurism in the Brazilian public health system in a 12-year interval. Methods: Data from procedures performed between 2008 and 2019 were extracted from the national public database (Departamento de Informática do Sistema Único de Saúde, or DATASUS) using web scraping techniques. Procedures were evaluated regarding the yearly frequency of elective or urgency surgeries, in-hospital mortality, and governmental costs. All tests were done with a level of significance P<0.05. Results: A total of 812 procedures were analyzed. Of all surgeries, 67.98% were elective cases. There were 328 in-hospital deaths (mortality of 40.39%). In-hospital mortality was lower in elective procedures (26.92%) than in urgency procedures (46.74%) (P=0.008). Total governmental expenditure was $3.127.051,56 — an average of $3.774,22 for elective surgery and $3.791,93 for emergency surgery (P=0.999). Conclusion: The proportion of urgency procedures is higher than that recommended by international literature. Mortality was higher for urgent admissions, although governmental costs were equal for elective and urgent procedures; specialized referral centers should be considered by health policy makers.

Epidemiological analysis of 556 procedures of open thoracoabdominal aortic aneurysm repair in the Public Health System in the largest Brazilian city

ABSTRACT Objective Despite the development of endovascular procedures, open repair remains the gold standard for the treatment of aortic thoracoabdominal aneurysms and some type B dissections, with well-established good outcomes and long-term durability at high-volume centers. The present study described and analyzed public data from patients treated in the public system in a 12-year interval, in a city where more than 5 million inhabitants depend on the Public Health System. Methods Public data from procedures performed between 2008 and 2019 were extracted using web scraping techniques. The variables available in the database include sex, age, elective or emergency hospital admission, number of surgeries, in-hospital mortality, length of stay, and information on reimbursement values. Results A total of 556 procedures were analyzed. Of these, 60.79% patients were men, and 41.18% were 65 years of age or older. Approximately 60% had a residential address registered in the municipality. Of all surgeries, 65.83% were elective cases. There were 178 in-hospital deaths (mortality of 32%). In the elective context, there were 98 deaths 26.78% versus 80 deaths (42.10%) in the emergency context (p=0.174). Mortality was lower in the hospitals that performed more surgeries. A total of USD 3,038,753.92 was paid, an average of USD 5,406.95 for elective surgery and USD 5,074.76 for emergency surgery (p=0.536). Conclusion Mortality was no different between groups, and hospitals with higher volume presented more favorable outcomes. Specialized referral centers should be considered by health policy makers.

Morphological and hemodynamic patterns of carotid stenosis treated by endarterectomy with patch closure versus stenting: a duplex ultrasound study

OBJECTIVES: A duplex ultrasound study was performed to investigate morphological and hemodynamic patterns of carotid stenoses treated by endarterectomy with patch closure versus stenting. MATERIALS AND METHOD: Twenty-nine carotid stenoses were treated with stenting and 65 with patch closure. Duplex ultrasound parameters (luminal diameter, mm; peak systolic velocity and end-diastolic velocity, cm/s) were measured 24 hours after the procedures and also at 12 months post-procedure. Residual stenoses (immediately postprocedure) and restenoses (within 12 months of procedure) were defined as narrowings of >50 percent on duplex ultrasound examination. RESULTS: In stented patients, the luminal diameter of the proximal internal carotid artery increased in the interval between the 24-hour and 12-month post-procedure studies, while in the patch closure patients, the diameter decreased. Carotid hemodynamics normalized immediately after both patching and stenting and remained relatively stable thereafter up to 12 months. No statistically elevated flow velocities (in the absence of residual stenosis or restenosis) were observed in the patched or stented carotid arteries. No significant differences in residual stenosis rates were observed between the stenting group (3 cases, 10.34 percent) and the patch closure group (1 case, 1.53 percent, P = 0.08). At 12 months, 2 stenting patients (6.88 percent) and 2 patch closure patients (3.07 percent) had $50 percent restenosis (P = 0.58). One case of late stroke due to restenosis was observed in the stenting group; the patient died 12 months postoperatively, before receiving new intervention. CONCLUSION: Measurements over time in luminal diameter signalized differences in arterial remodeling mechanisms between patched and stented carotids. Both stenting and patch closure were associated with carotid patency and flow restoration. This study does not support a general approach to new velocity criteria indiscriminately applied to stented or patched carotids.

Fenestração aórtica endovascular na dissecção aguda complicada por isquemia visceral e perfiérica / Endovascular aortic fenestration for acute dissection complicated by visceral and peripheral ischemia

Os autores relatam um caso de tratamento paliativo de isquemia periférica causada por dissecção aguda da aorta tipo B de Stanford por meio de fenestração aórtica endovascular. Mais de 90 por cento dos pacientes com dissecção aaguda da aorta, se não tratados, morrem em 3 a 6 meses. O tratamento clínico inicial e definitivo para dissecção aguda da aorta do tipo B é preconizado pela maioria dos importantes centros, reservando-se o tratamento cirúrgico para suas complicações, como isquemia periférica, que é a mais frequente, ocorrendo em 35 por cento das vezes. Os autores também descrevem aspectos da fenestração cirúrgica cnvencional, comparandoa coma técnica percutânea.

Estudou-se 60 fígados de cadáveres frescos adultos com o tronco celíaco, cabeça do pâncreas e artéria mesentérica. A veia porta direita, esquerda e seus ramos foram dissecados bem como as veias hepáticas. Encontrou-se ramo único da veia hepática direita em 59(98,3 por cento) casos, média em 53(88,3 por cento) e a esquerda em apenas 46(76,3 por cento). Em 59(98,3 por cento) casos havia os ramos portais direitos e esquerdos porém em um (1,6 por cento) näo havia bifurcaçäo da veia prota. A veia porta média foi encontrada em novel(15,2 por cento) casos. Em conclusäo, a técnica do "split-liver" seria contra-indicada no caso de näo bifurcaçäo portal

Estado atual do "split-lever" como opcao tecnica para o transplante de figado: revisao da literatura / An update of split liver as a technical option of liver transplantation: review of literature

A falta de doadores de orgaos e um fator critico que limita o emprego do transplante ortotopico de figado em nosso meio. O "split-liver" refere-se a seccao regrada do figado de um doador para implante em dois receptores. Os autores revisaram a literatura e observaram que apesar desta tecnica possuir indices de complicacoes pos-operatorias e mortalidade superiores ao transplante habitual constitui-se em boa opcao tecnica para pacientes cronicamente em listas de espera bem como aqueles com insuficiencia hepatica aguda e subaguda que necessitam de um novo orgao para manterem-se vivos.
