Postoperative “Chimney” for Unintentional Renal Artery Occlusion after EVAR
نویسندگان
چکیده
Renal artery obstruction during endovascular repair of abdominal aortic aneurysm using standard device is a rare but life-threatening complication and should be recognized and repaired rapidly in order to maintain renal function. Both conventional surgery and endovascular stenting have been reported. We report a case of late postoperative bilateral "chimney" to resolve a bilateral thrombosis of the renal artery following an uncomplicated endovascular aortic repair.

Post-EVAR type III endoleaks present a particular challenge as they carry a significant risk of rupture. We present a case of an 81-year-old gentleman, 10 years post-EVAR, with complex type III endoleak with component separation that was successfully treated with a combination of left renal artery chimney, aortouniiliac stent grafting and femorofemoral crossover bypass.

The purpose of this paper is to report a salvage maneuver for accidental coverage of both renal arteries during endovascular aneurysm repair (EVAR) of an infrarenal abdominal aortic aneurysm (AAA). A 72-year-old female with a 6 cm infrarenal abdominal aortic aneurysm was treated by endovascular means with a standard bifurcated graft. Upon completing an angiogram, both renal arteries were found ...
متن کاملTreating patients with abdominal aortic aneurysm with endovascular repair and the crossover chimney technique in the internal iliac artery to protect the unilateral internal iliac artery.
This study aims to explore the treatment methods for patients with abdominal aortic aneurysms (AAAs) that required occlusion of the openings of the bilateral internal iliac arteries (IIAs) in endovascular aneurysm repair (EVAR) and to evaluate the efficacy of these treatments. Four patients with AAA were treated with endovascular aneurysm repair (EVAR) and the crossover chimney technique in the...
