Wrap–clipping for a ruptured blood blister–like (“dorsal”) ICA aneurysm

Abstract

  Ruptured blood blister‒like internal carotid artery (ICA) aneurysms have recently been treated with trapping and high‒flow bypass. Although this treatment is very effective and useful to prevent re‒rupture, there are some concerns related to the surgery; it is time‒consuming and accompanied by a risk of ischemic complications. We introduce the wrap‒clipping technique to treat fragile lesions. This technique can preserve the anterograde blood flow of the ICA. However, the possibility of some stenosis caused by wrap‒clipping should be monitored carefully after the surgery.
