Abstract: | Background:To evaluate the feasibility of a new surgeon-modified iliac branch device (IBD) technique to maintain pelvic perfusion in the management of common iliac artery (CIA) aneurysm during endovascular aneurysm repair (EVAR).Methods:From January 2011 to December 2013, a new surgeon-modified IBD technique was performed in department of vascular surgery of Peking Union Medical College Hospital in five patients treated for CIA aneurysm with or without abdominal aortic aneurysm. A stent-graft limb was initially deployed in vitro, anastomosed with vascular graft, creating a modified IBD reloaded into a larger sheath, with or without a guidewire preloaded into the side branch. The reloaded IBD was then placed in the iliac artery, with a covered stent bridging internal iliac artery and the branch. Finally, a bifurcated stent-graft was deployed, and a limb device was used to connect the main body and IBD.Results:Technical successes were obtained in all patients. The mean follow-up length was 24 months (range: 6–38 months). All grafts remained patent without any sign of endoleaks. There were no aneurysm ruptures, deaths, or other complications related to pelvic flow.Conclusions:Using the surgeon-modified IBD to preserve pelvic flow is a feasible endovascular technique and an appealing solution for personalized treatment of CIA aneurysm during EVAR. |
