Trombose ,HSM CIR VASC ,Falso Aneurisma - Abstract
Introdução: O elevado número de procedimentos vasculares percutâneos resulta num aumento das complicações relacionadas com o acesso vascular. A mais frequente é o falso aneurisma (FA), cuja intervenção de primeira linha é atualmente a injeção eco-guiada de trombina humana (IETH). Métodos: Estudo observacional retrospetivo realizado através da consulta de processos clínicos dos doentes submetidos a IETH por FA femoral num hospital terciário no período de 2008 a 2018. O end-point primário foi o sucesso desta modalidade terapêutica (trombose primária e à reavaliação ecográfica). Os end-points secundários foram complicações relacionadas com o procedimento, reintervenções, duração de internamento e sobrevida. Resultados: A amostra incluiu 102 doentes. 97% dos FA tinham etiologia iatrogénica confirmada. 4% foram diagnosticados após intervenção pela Cirurgia Vascular e 85% após intervenção pela Cardiologia, dos quais 80% após cateterismo coronário e 13% após TAVI (transcatheter aortic valve implantation). 58% dos doentes estavam antiagregados e 50% anticoagulados. 80% dos FA ocorreram à direita. 65% afetavam a AFC e 35% a AFS ou AFP. O diâmetro médio dos FA tratados por IETH foi de 36,8mm. 29% apresentavam-se lobulados (FA complexos). Quanto às características do colo do FA, 58% tinham colo longo (≥3mm de comprimento) e 58% tinham colo estreito (

HSM CIR VASC ,Fístula aorto-cava ,Aneurisma da aorta abdominal ,Estudos Retrospetivos - Abstract
Introdução: A fístula aorto-cava primária (FAC) é uma entidade clínica rara, associada a menos de 1% dos AAA. As principais manifestações clínicas são insuficiência cardíaca aguda (ICA), edema dos membros inferiores, lesão renal aguda (LRA) e insuficiência hepática aguda (IHA). A cirurgia convencional associa-se a elevada mortalidade (16–66%)(1). Apesar da limitada evidência acerca da abordagem desta patologia, o tratamento endovascular, quando exequível, aparenta ser eficaz e associado a menor morbimortalidade. Os autores têm como objetivo descrever a apresentação clínica, terapêutica e resultados dos AAA complicados de FAC num hospital terciário e comparar com os dados disponíveis na literatura. Material e Métodos: Análise retrospetiva dos AAA complicados de FAC tratados entre Janeiro de 2014 e Maio de 2020 num hospital terciário. Os dados foram colhidos através da consulta do processo clínico eletrónico e foram incluídas variáveis demográficas, clínicas, do procedimento e eventos clínicos pós-operatórios. Resultados: Durante este período, identificaram-se quatro doentes com AAA complicado de FAC submetidos a cirurgia emergente. Os doentes eram do sexo masculino, com idade média de 70(±8) anos e história de tabagismo (n=4). Na admissão, os sintomas mais comuns foram dor lombar (n=4) e hipotensão/taquicardia (n=4). Outros sinais/sintomas frequentes foram massa abdominal pulsátil (n=3) e LRA/hematúria (n=2). Em dois doentes, a AngioTC na admissão revelou AAA com hematoma retroperitoneal sem evidência de FAC, que apenas foi diagnosticada intra-operatoriamente. Dois doentes foram submetidos a interposição aorto-bi-ilíaca com rafia endoaneurismática da fístula; um foi submetido a pontagem aorto-bi-femoral com rafia endoaneurismática da fístula e um foi submetido a exclusão endovascular com endoprótese aorto-bi-ilíaca Gore Excluder C3®. As perdas hemáticas foram muito superiores nos doentes submetidos a cirurgia convencional. As complicações pós-operatórias mais frequentes foram a LRA (n=3), insuficiência respiratória (n=2) e IHA (n=2). O doente submetido a EVAR aorto-bi-ilíaco não apresentou qualquer complicação pós-operatória, tendo alta ao 7º dia pós-operatório. Até aos 30 dias, verificou-se uma reintervenção: hemicolectomia esquerda por colite isquémica no 1º dia pós-operatório de cirurgia convencional. Após os 30 dias, observou-se 1 reintervenção: implantação de endoprótese bifurcada ilíaca por aneurisma ilíaco direito, no doente submetido a EVAR. Em dois casos, verificou-se o óbito no período pós-operatório precoce (2º e 3º dia). Os restantes doentes têm um follow-up de 66 e 29 meses. Conclusões: A FAC pode ocorrer em associação ou não a rotura de AAA com hematoma retroperitoneal e, nalguns casos, não é evidente na AngioTC e apenas detetada intra-operatoriamente. Tendo em conta a nossa experiência e o descrito na literatura, deve existir um elevado índice de suspeição para esta complicação dos AAA nos casos de congestão venosa aguda com disfunção orgânica de novo (LRA, ICA, IHA), mesmo na presença apenas de hematoma retroperitoneal imagiologicamente. A cirurgia convencional com rafia ndoaneurismática da FAC e interposição protésica foi a técnica cirúrgica de eleição. No entanto, o tratamento endovascular, se exequível, aparenta ser eficaz e com menor morbilidade e mortalidade nos AAA complicados de FAC. O não encerramento da comunicação aorto-cava por via endovascular não parece resultar em morbilidade significativa. Se se verificar preenchimento da fístula por endoleak tipo II, apesar da evidência escassa na literatura, a vigilância clínica e imagiológica parece ser uma opção segura, desde que se associe a evolução favorável do saco aneurismático e ausência de sintomas. info:eu-repo/semantics/publishedVersion

Introdução: A incidência de isquemia aguda renal é baixa. A experiência publicada do seu tratamento cirúrgico resume-se a séries de casos e não há indicações bem definidas para a revascularização renal em caso de isquemia aguda. Métodos: Estudo observacional retrospetivo realizado com base na consulta de processos clínicos de doentes submetidos a revascularização de artéria renal por isquemia aguda renal, num hospital universitário terciário, de Janeiro de 2011 a Junho de 2020. O endpoint primário foi a taxa de diálise aos 30 dias e os endpoints secundários foram a taxa de doença renal crónica de novo aos 30 dias e a sobrevida aos 30 dias. Resultados: Foram incluídos 11 doentes com isquemia aguda renal. As causas da oclusão arterial renal foram: disseção aórtica (N=3), trombose de artéria renal nativa (N=3), trombose de revascularização renal prévia (N=3), embolia (N=1) e trauma fechado (N=1). Dois dos casos corresponderam a doentes com rim único. A mediana de tempo desde o início do quadro até à revascularização cirúrgica foi de 24 horas. Dois doentes apresentavam doença renal crónica prévia conhecida. A apresentação clínica foi de dor lombar ou abdominal (n=8), HTA não controlada (N=5) e/ou oligoanúria (N=5). O diagnóstico foi realizado em todos com recurso a angio-TC. Em todos os doentes, a artéria renal principal estava afetada (N=9 desde o seu óstio) e havia algum grau de captação de contraste pelo rim afetado. Em todos os casos, foi realizada a revascularização unilateral de uma artéria renal com sucesso angiográfico, com exceção de um dos três casos em que a isquemia renal era bilateral, em que ambas as artérias renais ocluídas foram revascularizadas. Com exceção de um doente com oclusão de stent (submetido a angioplastia com DCB), todos foram submetidos a angioplastia com stent (6 com stents cobertos). Dois doentes apresentaram oligoanúria no pós-operatório e quatro necessitaram de pelo menos uma sessão dialítica. Aos 30 dias, a taxa de diálise foi de 11% (doente com isquemia aguda renal bilateral de etiologia traumática com 13 horas de evolução) e a taxa de doença renal crónica de novo de 22%. A sobrevida aos 30 dias foi de 90%. Conclusão: Nesta população de doentes, pode-se verificar a reversão da isquemia aguda renal mesmo após oclusões prolongadas das artérias renais. No entanto, com os dados disponíveis, não é possível anteceder quais os doentes que recuperarão a função renal prévia após revascularização urgente com sucesso angiográfico. Por ser rápido e pouco invasivo, o tratamento endovascular é a primeira linha no tratamento cirúrgico da isquemia aguda renal na nossa instituição. info:eu-repo/semantics/publishedVersion

HSM CIR VASC ,Infeção - Abstract
Introdução: A infeção protésica é uma das complicações mais temidas da cirurgia aórtica (0,19% após cirurgia convencional e 0,16% após EVAR). Os autores relatam um caso raro de infeção secundária de patch de pericárdio bovino utilizado no reforço da laqueação de coto aórtico por explante de prótese aorto-bifemoral infectada. Caso clínico: Doente de 53 anos, com antecedentes de HTA, cardiopatia hipertensiva, hipercolesterolémia, ex fumador e status pós AVC, foi submetido em 2015 a bypass aorto-bifemoral com prótese de Dacron® por doença aorto-ilíaca oclusiva. Em outubro 2019 apresenta em angio TC sinais de infeção protésica e fistula aorto paraprotésica ABF — duodenal (D3). Iniciou AB dirigida com vancomicina e foi submetido a bypass axilo-bifemoral e, após 5 dias, a remoção de prótese de bypass aorto-bifemoral, laqueação de coto aórtico e secção do jejuno proximal. A microbiologia da prótese identificou Candida glabrata, Enterobacter cloacae e Klebsiella pneumoniae. Após alguns meses, em angio TC de seguimento foi detetada coleção com cerca de 38 x 34mm de dimensão, justa coto aórtico, cujas características sugeriam tratar-se de coleção infetada pelo que o doente foi submetido a drenagem e desbridamento cirúrgico por abordagem retroperitoneal através de tóraco-freno-laparotomia. Procedeu-se à excisão do tecido infectado, incluindo o pericárdio bovino usado como reforço da laqueação aórtica. A biópsia do patch identificou Candida glabrata e no líquido pericoto aórtico foi identificado, para além do acima referido, Enterococcus faecium. Conclusão: Em doentes com baixo perfil de risco, uma estratégia cirúrgica agressiva oferece as melhores hipóteses de tratamento eficaz em contexto de infeção de prótese aórtica e posteriormente de infeção de patch de coto aórtico. No entanto estes doentes carecem de vigilância a longo prazo dado o risco de reinfeção local. A utilização de pericárdio bovino em zona contaminada pode resultar na sua infeção secundária, pelo que devem ser privilegiados enxertos autólogos sempre que possível. info:eu-repo/semantics/publishedVersion

Aneurisma da Aorta Abdominal ,Tratamento ,HSM CIR VASC ,Colo - Abstract
Introdução: O tratamento endovascular representa o método de eleição para o tratamento de Aneurismas da Aorta Abdominal (AAA). Existem endopróteses disponíveis com diâmetros do colo proximal até 36mm, que permitem o tratamento de colos proximais até 32 mm. Contudo, a existência de colos largos representa um conhecido preditor de complicações. O objetivo deste estudo é avaliar os resultados a médio-prazo de doentes que requereram endopróteses de 34-36mm. Métodos: Foi realizada uma análise retrospetiva de uma base de dados prospetiva, incluindo todos os pacientes submetidos a EVAR por AAA degenerativo numa instituição terciária na Holanda. Todas as medições foram realizadas em reconstruções center-lumen line em software dedicado. Os pacientes foram classificados como “diâmetro largo” (LD), se a endoprótese implantada tivesse diâmetro superior a 32 mm.. Os restantes pacientes foram classificados como diâmetro normal (ND). O endpoint primário foi complicações relacionadas com o colo (combinação de endoleak tipo IA, migração>5mm ou qualquer intervenção no colo proximal). Alterações morfológicas no colo e sobrevida foram também analisadas. Diferenças entre grupos foram ajustadas por regressão multivariável. Resultados: O estudo incluiu 502 pacientes (90 no grupo LD e 412 no grupo ND). O follow-up mediano foi de 3.5 anos IQR (1.5–6.2) e 4.5 anos IQR (2.1–7.3) para os grupos LD e ND, respetivamente, P=.008. Relativamente às características basais, os doentes no grupo LD, apresentavam maior incidência de hipertensão arterial (83% vs 69.7%, P=.012) e tabagismo (86% vs 84.1%, P=.018). Além de colos mais largos (colo Proximal Ø > 28 mm: 75% vs 3.3%, P45º: 21% vs 9%, P=.002), cónicos (39.8% vs 20.3%, P25%: 42% vs 32.3%, P5 mm ocorreu similarmente entre grupos (7.8% vs 5.1%, P=.32). Reintervenções relacionadas com colo o foram também mais frequentes no grupo LD (13.3% vs 8.7%, P=.027). info:eu-repo/semantics/publishedVersion

- Abstract
Objective: Endovascular aneurysm repair (EVAR) became an increasingly preferred modality for abdominal aortic aneurysm (AAA) repair both in elective AAA repair (el-EVAR) and EVAR of a ruptured AAA (r-EVAR) setting. Ruptured AAAs usually have more hostile anatomies and less time for planning. Consequently, more complications may arise after r-EVAR. The purpose of this study was to compare mi-term outcomes between r-EVAR and el-EVAR. Methods: A retrospective cohort analysis of patients undergoing EVAR from 2000 to 2015 at a tertiary institution was performed. Patients with previous aortic surgery, nonatherosclerotic AAA and isolated iliac aneurysms were excluded. In-hospital casualties or patients who were intraoperatively converted to open repair were also excluded. For the midterm outcome analysis, only patients with at least two postoperative examinations (a 30-day computed tomography scan and a second postoperative examination performed 6 months or later) were considered. The primary end point was freedom from aneurysm-related complications (a composite of type I or III endoleak, aneurysm sac growth, migration of more than 5 mm, device integrity failure, AAA-related death, late postimplant rupture, or AAA-related secondary intervention). Freedom from secondary interventions, neck-related events (defined as a composite of type IA endoleak, migration of more than 5 mm, or preemptive neck-related secondary intervention) and late survival were secondary end points. The impact of device instructions for use (IFU) compliance on neck events was also assessed. Results: The study included 565 patients (65 r-EVAR and 500 el-EVAR). Eighty-two patients were treated outside proximal neck IFU, 13 in the r-EVAR group (21.3%) and 69 (14.5%) in the el-EVAR (P =.16). During the index hospitalization, there were more complications (12.3% vs 3.2%; P =.001) and reinterventions (12.3% vs 2.8%; P <.001) in the r-EVAR group. After discharge, median clinical follow-up time was 4.3 years (

- Abstract
Introduction: Worldwide, there is an increase in scrutiny after surgical treatment of a vast array of pathologies. Doing so, a large body of evidence clearly supports centralisation, such as teaching hospitals, where a larger caseload enables optimal outcomes. These institutions have a strong presence of surgical residents seeking training in both technical and non-technical skills. Inevitably, as part of training, they will be involved in the surgical treatment of those patients, even as the primary operator. We sought to investigate the impact of trainee performed procedures in outcomes of common vascular procedures of different technical complexity., Methods: A non-systematic MEDLINE and Scopus databases review on the outcomes of resident performed common vascular procedures was performed., Results: Specific evidence in many procedures (venous disease, aortic aneurysms, peripheral artery disease) is lacking. After carotid endarterectomy (CEA), resident performed procedures seem to have similar cranial nerve palsy and stroke when compared to expert surgeons. Generally, resident-performed primary radiocephalic and elbow arteriovenous fistula (AVF) presents similar primary and secondary patency. As with CEA, AVF procedures performed by residents took longer. On aortic aneurysms, although no specific comparison has been performed, resident involvement (irrespective of surgeon or assistant) in these procedures does not seem associated with increased adverse events., Conclusion: In most vascular surgery procedures, little is known about resident performance and their impact on outcomes. Notwithstanding, resident-performed CEA and primary AVF seem free of major compromise to patients. Further research is warranted to clarify this topic.

- Abstract
Objective: Post-implantation syndrome (PIS), characterised by malaise, fever, and increased inflammatory markers, is a common occurrence after endovascular aneurysm repair (EVAR), causing prolonged hospitalisation and increased cost. This study aimed to determine the incidence and short-term outcomes of PIS after fenestrated or branched procedures in aorto-iliac aneurysms compared with standard EVAR., Methods: A retrospective, comparative study from a tertiary academic institution was undertaken. All patients who underwent elective EVAR with polyester stent grafts from January 2015 to June 2021 were considered. Two groups were defined: standard EVAR (sEVAR) and complex EVAR (cEVAR). The latter included visceral fenestrated and branched or iliac branch and chimney stent grafts. The primary outcome was the incidence of PIS within three days of the index procedure. Secondary outcomes were short-term complications and risk factors for PIS. A multivariable model was constructed to correct for confounders., Results: Overall, 253 patients were included: 165 (65.2%) sEVAR and 88 (34.8%) cEVAR. Complex EVAR patients were younger, with larger aneurysms, had longer procedures, and were more likely to have intra-operative complications. The PIS incidence was 23.7% (n = 60), significantly higher in cEVAR (34.1% vs. 18.2%; p = .005) and increased with the complexity of the procedure (EVAR: 18.2% vs. EVAR + iliac branch device: 25.0% vs. fenestrated and branched EVAR: 36.2%; p = .030). On multivariable analysis, cEVAR (OR 2.833, 95% CI 1.295 - 6.198; p = .009) was associated with a significantly increased risk of PIS. No differences in short term outcomes according to PIS status were noted. Group sub-analysis for cEVAR patients did not reveal any statistically significantly different outcomes according to PIS occurrence., Conclusion: In this cohort, cEVAR procedures were associated with a significantly increased risk of developing PIS compared with standard infrarenal repair. Post-implantation syndrome also appears to have a benign course with no major impact on peri-operative outcomes after cEVAR. Further research to confirm these findings is required., (Copyright © 2023 European Society for Vascular Surgery. Published by Elsevier B.V. All rights reserved.)

- Abstract
Objective: Portuguese nationwide estimates indicate that 20% of abdominal aortic aneurysms (AAAs) are treated when ruptured. In these cases, intra-operative unfractionated heparin (UFH) usage rates vary widely. Evidence on this topic is scarce and focused on patients treated by open repair (OSR). The aim was to determine the influence of UFH on peri-operative thromboembolic events (TEs) and death in a cohort of ruptured AAA (rAAA)., Methods: Retrospective, single-centre, comparative study. From 2011 to April 2023, all consecutive rAAAs (endovascular repair [EVAR] and OSR) were considered. Primary outcomes were 30-day TE free survival and TE rates. The secondary outcome was 30-day death. Safety endpoints were procedural blood loss, blood product requirements, and secondary interventions due to haemorrhage. Using propensity score matching (PSM) each UFH patient was matched with one no UFH patient in a 1:1 ratio., Results: The study included 250 patients. After PSM, 190 patients were analysed (EVAR: 60.0% no-UFH vs. 64.4% UFH). TE free survival estimates favoured the UFH group (67.3% vs. 47.2%, p = .009; UFH adjusted odds ratio [aOR] 2.01, 95% confidence interval [CI] 1.04-4.17). TEs were more frequent in the no UFH group (20.0% vs. 44.2% patients, p < .001; UFH aOR 0.31, 95% CI 0.15-0.65 for any TE), driven by an increase in bowel ischaemia (17.9% no UFH vs. 3.2% UFH, p = .001). Most events occurred in the first 72 hours. EVAR was associated with reduced TE and improved TE free survival (aOR 0.20, 95% CI 0.09-0.45 and aOR 5.54, 95% CI 2.34-13.08, respectively). No significant differences in 30-day survival were noted (75% no-UFH vs. 83% UFH, p = .26; aOR 1.08, 95% CI 0.48-2.43) nor in blood loss, peri-operative red blood cell and fresh frozen plasma requirements, or secondary interventions due to haemorrhage ( p = .10; p = .11; p = .13 and p = .18 respectively)., Conclusion: In this cohort, intra-operative UFH was safe and associated with improved TE free survival, driven by a reduction in bowel ischaemia. Conversely, mortality remained unaffected. Randomised controlled trials are required to confirm these findings., Competing Interests: Frederico Bastos Gonçalves has received speaker and proctoring fees from W.L.

- Abstract
A 42-year-old previously healthy male presented with 5 days of spontaneous mid-epigastric intense abdominal pain and mild epigastric tenderness on palpation. CT angiography revealed a Sakamoto type 2 isolated superior mesenteric artery dissection (SMA) with a "cul-de-sac" shaped false lumen (B- C: large arrow), side branch perfusion from both lumens, and compression of the true (A-D: small arrow) by the false lumen (A-D: large arrow). Dissection flap presented just distal to an aberrant right hepatic artery arising from the SMA (B.D: star). CT, clinical and analytic findings did not suggest visceral compromise and was successfully treated with bowel rest and anticoagulation. He is now on close clinical and imaging follow-up.

- Abstract
Objective: The aim of this study was to investigate the association between post-implantation syndrome (PIS) and long term outcomes, with emphasis on cardiovascular prognosis., Methods: One hundred and forty-nine consecutive patients undergoing EVAR in a tertiary institution were previously included in a study investigating the risk factors and short term consequences of PIS (defined as tympanic temperature ≥ 38°C and CRP > 10 mg/L, after excluding complications with an effect on inflammatory markers). This study was based on a prospectively maintained database. Survival status was derived from inquiry of civil registry database information and causes of death from the Dutch Central Bureau of Statistics. The primary endpoint was cardiovascular events. Secondary endpoints were overall and specific cause mortality (cardiovascular, ischaemic heart disease, AAA, and cancer related mortality). Aneurysm sac dynamics and occurrence of endoleaks were also analysed. Survival estimates were obtained using Kaplan-Meier plots and a multivariable model was constructed to correct for confounders., Results: The PIS incidence was 39% (58/149). At the time of surgery, patients had a mean age of 73 ± 7 years and were predominantly male. There were no baseline differences between the PIS and non-PIS groups. The median follow up was 6.4 years (3.2 - 8.3), similar in both groups (p = .81). There was no difference in cardiovascular events for PIS and non-PIS patients (p = .63). However, Kaplan-Meier plots suggest a trend towards a higher rate of cardiovascular events in PIS patients during the first years: freedom from cardiovascular events at one year was 94% vs. 89% and at three years 90% vs. 82%. No differences were found in overall and specific cause mortality. There was a higher rate of type II endoleaks for non-PIS patients (28% vs. 9%, p = .005). Sac dynamics were similar in both groups., Conclusion: The results suggest that PIS is not associated with a statistically significantly higher risk of cardiovascular events. PIS had no impact on mortality. Lastly, PIS patients had fewer type II endoleaks, but sac dynamics were analogous., (Copyright © 2021 European Society for Vascular Surgery. Published by Elsevier B.V.

- Abstract
Purpose: To compare changes in abdominal aortic aneurysm (AAA) sac volume between endovascular aneurysm repairs (EVAR) performed for ruptured (rEVAR) vs intact (iEVAR) AAAs and to determine the impact of early volume shrinkage on future complications., Materials and Methods: A retrospective analysis was performed of all patients undergoing standard infrarenal EVAR from 2002 to 2016 at a tertiary referral institution. Only patients with degenerative AAAs and with 30-day and 1-year computed tomography angiography (CTA) imaging were included. Early sac shrinkage was defined as a volume sac reduction >10% between the first (<30-day) and the 1-year CTA. The primary endpoint was to compare AAA sac volume changes between patients undergoing rEVAR (n=51; mean age 71.0±8.5 years; 46 men) vs iEVAR (n=393; mean age 72.3±7.5 years; 350 men). Results are reported as the mean difference with the interquartile range (IQR Q1, Q3). The secondary endpoint was freedom from aneurysm-related complications after 1 year as determined by regression analysis; the results are presented as the hazard ratio (HR) and 95% confidence interval (CI)., Results: At baseline, the rEVAR group had larger aneurysms (p<0.001) and shorter (p<0.001) and more angulated (p=0.028) necks. Aneurysm sac volume decreased more in the rEVAR group during the first year [-26.3% (IQR -38.8%, -12.5%)] vs the iEVAR group [-11.9% (IQR -27.5%, 0); p<0.001]. However, after the first year, the change in sac volume was similar between the groups [-3.8% (IQR -32.9%, 31.9%) for rEVAR and -1.5% (IQR -20.9%, 13.6%) for iEVAR, p=0.74]. Endoleak occurrence during follow-up was similar between the groups. In the overall population, patients with early sac shrinkage had a lower incidence of complications after the 1-year examination (adjusted HR 0.59, 95% CI 0.39 to 0.89, p=0.01)., Conclusion: EVAR patients treated for rupture have more pronounced aneurysm sac shrinkage compared with iEVAR patients during the first year after EVAR. Patients presenting with early shrinkage are less likely to encounter late complications. These parameters may be considered when tailoring surveillance protocols.

- Abstract
Objective: Endovascular aneurysm repair (EVAR) became an increasingly preferred modality for abdominal aortic aneurysm (AAA) repair both in elective AAA repair (el-EVAR) and EVAR of a ruptured AAA (r-EVAR) setting. Ruptured AAAs usually have more hostile anatomies and less time for planning. Consequently, more complications may arise after r-EVAR. The purpose of this study was to compare mi-term outcomes between r-EVAR and el-EVAR., Methods: A retrospective cohort analysis of patients undergoing EVAR from 2000 to 2015 at a tertiary institution was performed. Patients with previous aortic surgery, nonatherosclerotic AAA and isolated iliac aneurysms were excluded. In-hospital casualties or patients who were intraoperatively converted to open repair were also excluded. For the midterm outcome analysis, only patients with at least two postoperative examinations (a 30-day computed tomography scan and a second postoperative examination performed 6 months or later) were considered. The primary end point was freedom from aneurysm-related complications (a composite of type I or III endoleak, aneurysm sac growth, migration of more than 5 mm, device integrity failure, AAA-related death, late postimplant rupture, or AAA-related secondary intervention). Freedom from secondary interventions, neck-related events (defined as a composite of type IA endoleak, migration of more than 5 mm, or preemptive neck-related secondary intervention) and late survival were secondary end points. The impact of device instructions for use (IFU) compliance on neck events was also assessed., Results: The study included 565 patients (65 r-EVAR and 500 el-EVAR). Eighty-two patients were treated outside proximal neck IFU, 13 in the r-EVAR group (21.3%) and 69 (14.5%) in the el-EVAR (P = .16). During the index hospitalization, there were more complications (12.3% vs 3.2%; P = .001) and reinterventions (12.3% vs 2.8%; P < .001) in the r-EVAR group. After discharge, median clinical follow-up time was 4.3 years (interquartile range, 2.1-7.0 years) without differences between both groups. Five-year freedom from AAA-related complications was 53.9% in the r-EVAR group and 65.4% in the el-EVAR (P = .21). In multivariable analysis the r-EVAR group was not at increased risk for late complications (hazard ratio [HR], 0.94; 95% confidence interval [CI], 0.54-1.61; P = .81). Five-year freedom from neck-related events was 74% in r-EVAR and 82% in the el-EVAR group (P = .345). Patients treated outside neck IFU were at greater risk for neck-related events both in r-EVAR (HR, 6.5; 95% CI, 1.8-22.9; P = .004) and el-EVAR group (HR, 2.6; 95% CI, 1.5-4.5; P < .001). Freedom from secondary interventions at 5 years was 63.0% for r-EVAR and 76.9% for el-EVAR (P = .16). Survival at 5 years was 68.8% in the r-EVAR group and 73.3% in the el-EVAR group (P = .30)., Conclusions: Durable and sustainable midterm outcomes were found for both r-EVAR and el-EVAR patients who survived the postoperative period. Patients treated outside the IFU are at greater risk for late complications. Surveillance protocols may be tailored according to individual anatomy and IFU compliance rather than timing of repair., (Copyright © 2019 Society for Vascular Surgery. Published by Elsevier Inc.

- Abstract
Vascular procedures in general, and specifically abdominal aortic aneurysm (AAA) repair, are associated with worse outcomes in female patients. However, how female gender influences outcomes in the setting of aneurysm-rupture remains unclear and may be even more pronounced when compared to elective operations. In this report, the authors aim to review the literature regarding ruptured AAA repair in women. Using the traditional threshold for AAA of 30 mm of maximum diameter, the prevalence in women is lesser than in men. However, the true prevalence may be underestimated due to gender discrepancies in normal aortic diameter. For females, aneurysmal disease seems to manifest later, have more associated comorbidities, and rupture occurs at smaller aortic diameters. This has obvious implications for management. There is still no consensus over the optimal treatment for ruptured AAA in women. They are less frequently treated by endovascular aneurysm repair, possibly due to anatomical restrains. When feasible, endovascular repair shows better outcomes, at least in the short-term, and there is new evidence suggesting a lasting benefit as well. For open repair the results are consensually worse when compared to male counterparts. Finally, despite benefitting of apparently similar healthcare, women have a lower relative survival after rAAA repair when compared to men. Further investigation to determine the reasons of these discrepancies is warranted.

- Abstract
Durability of endovascular aneurysm repair is critical, since a significant proportion of patients suffer from procedure-related complications and secondary interventions after repair of abdominal aortic aneurysms. Therefore, regular follow up including imaging is recommended. The rationale behind current surveillance programs is to allow early detection and elective treatment of complications. However, current recommendations are laborious and resource consuming, may be deleterious to many patients and are largely inefficient. Furthermore, they do not account for novel imaging modalities or for the use of new endovascular devices. The authors review the current recommendations from international societies, and of the evidence for new imaging modalities that could be as alternatives, namely contrast enhanced ultrasound, three-dimensional contrast-enhanced ultrasound and digital tomosynthesis. The evidence on surveillance after repair with new devices, specifically with sealing technology, and its imaging specificities is also discussed. Lastly, the authors review the evidence for risk stratification of surveillance. Stratified follow up regimes may be based on preoperative anatomical characteristics or on postoperative imaging results, at different time points. Effective sealing, absence of endoleaks and sac dynamics are the most commonly used factors for stratification. In conclusion, there is still no consensus on surveillance after endovascular aneurysm repair, with regard to both modality and timing. Novel devices, and especially those using sealing technology, require more intensive surveillance as the expected results at mid- and long-term remain undetermined. Risk stratification of follow-up seems possible but still requires prospective validation before generalization.

- Abstract
Introduction: Subclavian artery pseudoaneurysms are rare and occur mostly as a consequence of an inadvertent arterial puncture during central venous catheterization, endovascular therapeutic procedures or after penetrating or blunt trauma. They usually have a late clinical presentation, with pain, swelling or other compressive symptoms. The optimal treatment in this situation is still a matter of debate. The authors describe a case of late presentation of subclavian artery pseudoaneurysm after transjugular hepatic biopsy and discuss the several options for treatment., Methods: A 41-year-old woman was admitted in our hospital due to symptomatic subclavian artery pseudoaneurysm. She underwent a biopsy 20 years earlier for an undetermined febrile syndrome. The pseudoaneurysm was diagnosed during investigation of a right non-pulsatile cervical mass that was associated to cervical edema and Horner's syndrome. CTA revealed a pseudoaneurysm of right subclavian artery with 35 mm of diameter and an arteriovenous fistula to jugular vein which presented with significant enlargement. Additionally, the vertebral venous plexus was also ingurgitated. The pseudoaneurysm caused a left shift of the thyroid, common carotid artery and trachea. The vertebral artery arised 4 mm distal to pseudoaneurysm., Results: After a multidisciplinary evaluation including vascular surgery, neuroradiology and cardiac surgery, she underwent surgical exclusion of false aneurysm and arteriovenous fistula via partial upper sternotomy with cervicotomy. Care was taken to preserve the vertebral artery. There was a complete resolution of compressive symptoms and there were no complications during the first year of follow up., Conclusion: Subclavian artery pseudoaneurysms impose a major surgical challenge, especially when originating from the proximal third. Large pseudoaneurysms may rupture or produce signs and symptoms of compression. If intervention is considered necessary, several options are available: open surgical resection and vascular reconstruction, endovascular exclusion, stentgraft implantation or ultrasound-guided thrombin injection have all been described. The choice of procedure should be tailored to the patient, based on comorbidities, clinical presentation and anatomic characteristics. When compressive symptoms exist, an open approach is advised. However, because of their location, surgical exposure of the pseudoaneurysm may be technically difficult, requiring a sternotomy or a clavicular resection for adequate exposure. An endovascular approach demands an adequate landing zone and absence of severe tortuosity. When arteriovenous fistulae and enlargement of vertebral veins are verified, with subsequent increase in venous pressure, there is a risk of cervical radiculopathy (2-4%). This case report describes an uncommon presentation of subclavian pseudoaneurysm and exemplifies the complexity of their treatment.
