Rectum and sigmoid colon necrosis due to cholesterol embolization after implantation of an aortic stent-graft.
Endovascular treatment of abdominal aortic aneurysms (AAAs) with stent-grafts is increasingly performed. Recent studies have shown that stent-graft placement for AAA is technically feasible and can effectively exclude aneurysms from the circulation. However, complications related to the procedure, such as graft thrombosis, migration of the prosthesis, peripheral embolization, and leaks with incomplete exclusion of the aneurysmal sac, have been reported. We report a case of rectum and sigmoid colon necrosis with fatal outcome due to cholesterol embolization after implantation of a stent-graft for an infrarenal AAA.
