Endovascular Treatment of Type 1a Endoleak after Treatment of Suspending Rupture of Bilateral Internal Iliac Aneurysms for Preserving the Inferior Mesenteric Artery

Abstract

An 86-year-old man presented with lower abdominal pain. Enhanced CT revealed large bilateral internal iliac arterial aneurysms. After embolization of the bilateral internal iliac arteries, leg type stent grafts were implanted. 1 month later an enhanced CT showed a type 1a endoleak, so additional endovascular treatment was necessary. A bifurcated type stent graft was lowered into the terminal aorta to bail out the inferior mesenteric artery. The type 1a endoleak disappeared, nor were complications. The use of this simple and easy technique can prevent serious and fatal complications after bilateral internal iliac artery embolization.
