Preservation of internal iliac artery by using it as target vessel for distal anastomosis of bifurcated aortic grafts during surgical repair of aorto-iliac aneurysms

Le résumé fourni par la source

Common iliac artery aneurysms coexist with abdominal aortic aneurysms in 20-30% of cases and may present technical challenges during surgical reconstruction. Rarely, wide iliac bifurcations may be encountered which may render construction of the distal anastomosis in the iliac bifurcation not feasible. In this instance several techniques may be used, but our preferred approach is the anastomosis of the graft in the internal iliac with subsequent transposition of the external iliac artery in the graft limb. We describe this technique in 3 patients. Postoperative course was uneventful with no signs of pelvic or lower limb ischemia and 100% primary patency during 15 months. In conclusion, the anastomosis of the limb of a bifurcated graft with the internal and transposition of the external iliac artery onto the graft limb may simplify aorto-iliac reconstruction in case of wide iliac bifurcations and safely preserve flow in both internal and external iliac arteries.
