Endovascular treatment has become the preferred method of repair of abdominal and thoracic aortic aneurysms, and comes with a unique complication in the form of endoleaks (type I-IV). Type II endoleaks are the focus of this review. They are the most common form of endoleak detected in CT surveillance following endovascular repair. ⋯ Possible reasons for poor success rates will also be discussed. A general consensus on how to best manage these patients is yet to be reached. The aim of this review is to give an overview of type II endoleaks, their natural history and vessels most commonly involved, as well as different approaches to embolisation.

The study aims to analyze retrospective results of extensive endovascular repair of the descending thoracic aorta with special attention to spinal cord malperfusion. ⋯ The coverage of the entire thoracic aorta is an effective procedure with high probability of success. Spinal cord malperfusion remains a serious complication especially in patients with prior aortic surgery but if collateral blood supply is maintained the occlusion of intercostal arteries do not determine paraplegia or paraparesis. In order to consider acute or chronic occlusion of subclavian, lumbar or hypogastric arteries so preventing spinal cord ischemia, strong preoperative evaluation including analysis of previous surgery for abdominal aortic aneurysm repair and avoidance of T12 aortic segment coverage if feasible is mandatory.
