- W2922271610 abstract "Purpose To evaluate feasibility and effectiveness using the octopus endograft technique to treat complex aortic aneurysms (CAAs). Materials and Methods Endovascular repair of CAAs, including thoracoabdominal aneurysms (TAAAs) and dissections involving major side branches, was performed at a single center from June 2014 to June 2017. Patients included 9 men and 2 women (mean age, 60.5 y; range, 40–89 y) were included. The octopus technique was applied using standard aortic grafts with branch stent grafts to preserve the renovisceral arteries. Results Aortic pathologies comprised 3 mycotic aneurysms, 2 chronic dissections with acute rupture, 1 progressively enlarging chronic type B dissection, 1 acutely ruptured TAAA, and 4 unruptured TAAAs. Mean procedural and fluoroscopic times were 562 min (range, 324–840 min) and 183 min (range, 73–338 min), respectively. Three patients died within 1 month. Mean duration of follow-up was 26.3 months (range, 8–42 months) for remaining patients. Technical success rate of target vessel stent placement was 89.7% (35/39). Major complication rate was 45.5% (5/11), including 3 deaths, 1 permanent paraplegia, and 1 temporary paraplegia that resolved in 2 months. All 3 mycotic aneurysms with mean duration of follow-up of 29 months (range, 8–42 months) were excluded successfully without endoleak. Conclusions The octopus technique is feasible for treatment of CAAs requiring urgent management or with difficult anatomy without the use of available custom-made or off-the-shelf branched devices. The procedure carries substantial morbidity and mortality and requires further investigation for its long-term durability." @default.
