Results of elective and emergency endovascular repairs of popliteal artery aneurysms

Abstract

These results support elective EVPAR in anatomically suitable patients with increased risk for open repair; however, major adverse events after EVPAR, mainly after emergency repairs, are frequent. A prospective randomized multicenter study to justify EVPAR in the emergent setting is warranted.

A Systematic Review and Meta-analysis of Endovascular Popliteal Aneurysm Repair Using the Hemobahn/Viabahn Stent-Graft

“…There was no significant difference in primary patency for EVPAR compared with surgical repair, with a pooled HR of 1.30 (95% CI 0.79 to 12.14, p=0.189; Figure 2B). 14,15,18,21,24 A sensitivity analysis comparing primary patency in studies using both Hemobahn and Viabahn stent-grafts 14,20,21,23,25,26 compared to studies reporting Viabahn stent-grafts only [15][16][17][18][19]22,24,27 showed no significant difference in primary patency ( Figure 2C). …”

Cirurgia aberta e endovascular no tratamento de aneurisma de artéria poplítea: experiência de cinco anos do HCRP-FMRP-USP

“…8,[28][29][30] All of the endovascular cases were elective, but some studies have shown that this technique can also be used in urgent/emergency situations, with primary patency reaching 69%, and secondary patency of up to 91%, offering a less invasive option for patients at high risk from surgery, even in acute situations. 31 Studies report primary patency of 86% to 95% and secondary patency of 96.90% to 100% for aneurysms repaired with elective endovascular surgery. [31][32][33][34] Cases repaired with great saphenous vein grafts by conventional surgery have patency of 78.80% to 87.50% in the first year, with limb salvage rates of 94.30%.…”

Rupture of Giant Superficial Femoral Artery Aneurysm in a Leukemic Patient Submitted to Chemotherapy

“…Several procedures are described in the literature, such as excision, ligation, and bypass grafting with an autologous vein or prosthetic material. Nowadays, endovascular repair is also feasible and safe [4], but we ruled it out mainly due to the extension of the hematoma that had to be evacuated and the size of the aneurysm. Thrombocytopenia is a common side effect of azacitidine; our patient’s pre-operative platelet count was 17,000 platelets/μL.…”
