A noninterventional management approach to endovascular coil migration into the sigmoid colon.

A 75-year-old man underwent endovascular treatment of a right internal iliac artery (IIA) aneurysm by placing coils in the distal IIA and occluding the inflow with a common iliac artery-to-external iliac artery stent graft. Surveillance computed tomography angiography discovered migration of an endovascular coil from the thrombosed right IIA into the sigmoid colon. Subsequent serial imaging demonstrated uncomplicated extracorporeal passage of the coil. We review the relevant literature and treatment rationale. Published by Elsevier Inc.
