Research paper thumbnail of Up-and-Over Technique for Implantation of Iliac Branch Devices After Prior Aortic Endograft Repair

Journal of endovascular therapy : an official journal of the International Society of Endovascular Specialists, 2018

This technique uses a coaxial 12-F flexible sheath that is docked with a through-and-through wire into a 7-F sheath advanced from the contralateral femoral approach. This maneuver allows both sheaths to be moved as a unit while maintaining position of the apex of the system as it loops over the flow divider, avoiding damage to or displacing the extant endograft. Once the 12-F sheath is positioned in the iliac limb of the aortic stent-graft and secured in place with the through-and-through wire, the repair is extended into the internal iliac artery using a bridging stent-graft or covered stent introduced via a coaxial sheath. The up-and-over technique with a flexible 12-F sheath mated with a 7-F sheath from the opposite side allows bilateral femoral access to be used for iliac branch device placement after ...

Research paper thumbnail of Planning endovascular aortic repair with standard and fenestrated-branched endografts

Advantages include its minimal invasive approach and lower risk of mortality and morbidity compared to open surgical repair. In patients with complex aneurysms involving side branches, novel techniques of parallel, fenestrated and branched endografts have expanded the indications of EVAR. Preoperative planning is of paramount importance to achieve technical success and to minimize risks of these procedures. In most centers, anatomical measurements are based on helical computed tomography angiography and/or magnetic resonance angiography. This article summarizes the most important aspects on planning standard and complex EVAR to treat aortic aneurysms and dissections.

A cirurgia para o tratamento de obstruções no sistema venoso profundo não foi incorporada à prática da maioria dos cirurgiões vasculares, ficando restrita a poucos centros em alguns países. Com o advento da cirurgia endovascular, a possibilidade de tratar alguns tipos de lesões obstrutivas por uma técnica minimamente invasiva e com resultados promissores renova o interesse da comunidade vascular pelas formas mais complexas de doença venosa.

Research paper thumbnail of Outcome Analysis of Infrapopliteal Percutaneous Transluminal Angioplasty and Bypass Graft Surgery With Nonreversed Saphenous Vein for Individuals With Critical Limb Ischemia

Method: A total of 48 infrapopliteal PTAs and 50 infrapopliteal BGS were compared retrospectively. All grafts used nonreversed saphenous vein in a single length as a substitute. Results: Secondary patency and limb salvage rates in 24 months for the surgical group were 64.7% and 73.2%, respectively. For PTA group, these values were 63.7% and 68.2%, without differences between groups (log rank; P ¼ .45 and .39, respectively). Bypass graft surgery presented better results of secondary patency (72.9% vs 57.1%) and limb salvage (83.5% vs 53.6%) than PTA for patients with Transatlantic Inter-Society Consensus (TASC) D lesions (P ¼ .04 and P ¼ .01, respectively). Conclusions: Both BGS and PTA provided similar results of patency and limb salvage for individuals with infrapopliteal atherosclerotic disease presenting with CLI. Bypass graft surgery had better results than PTA when TASC D lesions were present.

We report the case of a 58-year-old male patient with diabetes mellitus, hypertension and end-stage renal disease in whom hemodialysis was conducted via a long-term catheter. His medical record described numerous central venous cannulations and several AVF creations. The patient developed subclinical subclavian stenosis that required creation of a new vascular access route. The purpose of this case report is to describe treatment of subclavian vein stenosis during AVF creation.

Design: Retrospective cohort study. Material and methods: Between 1995 and 2009, 47 bypass procedures to perigeniculate collateral arteries were performed in 46 patients (15 women, 31 men; median age, 68 years). All patients presented with critical ischaemia (tissue loss in 87.5%, rest pain in 12.5%). Mean ankle brachial index was 0.27 AE 0.17. The site of distal anastomosis was the descending genicular artery (DGA) in 23 bypasses (1 bilateral) and the medial sural artery (MSA) in 24. Proximal anastomosis was to the external iliac artery in 2 cases, common femoral artery in 23 cases, superficial femoral artery in 8 cases, deep femoral artery in 8 cases, above-knee poplitaeal artery in 2 cases, and previous graft in 4 cases. Results: There were four deaths during the immediate postoperative period. Mean follow-up duration was 27 months. Ten patients required major amputation. Mean ankle brachial index post-operatively was 0.60 AE 0.21. At 3 years, primary patency was 74.7 AE 7%, secondary patency was 83.4 AE 8%, and the limb salvage and survival rates were 73.5 AE 7% and 77.4 AE 7%, respectively. Conclusion: Bypass to perigeniculate arteries is a viable treatment option for critical limb ischaemia in selected patients. ª
