Endovascular Treatment of Common Iliac Aneurysm After Aortobifemoral Bypass: Banana Technique and Shape Memory Polymer Plug Embolization

<b>Objective:</b> This case report aims to present a new endovascular technique for arterial embolization using a relatively recently developed endovascular device, Shape Memory Polymer (SMP) Embolization Plug (IMPEDE, Shape Memory Medical). <b>Methods:</b> A 66-year-old man presented an asymptomatic common iliac aneurysm with a maximun diameter of 4.4 cm and a previous aorto-bifemoral bypass. <b>Results:</b> An embolization of the common iliac artery aneurysm with 5 units of IMPEDE-FX Rapid Fill (12 mm, Shape Memory Medical) and revascularization from external iliac artery to internal iliac artery through a banana technique with an auto-expandable covered stent (Viabahn 10 × 100 mm, Gore) was performed. <b>Conclusion:</b> The experience obtained after the use of this device has allowed us to increase the therapeutic arsenal for high volume aneurysm embolization.
