Balloon or Stent-Assisted Coil Embolization for Acutely Ruptured Wide-Necked Aneurysms

In this paper, we report five cases with acutely ruptured wide-necked aneurysms, which were treated with coil embolization using a balloon or stent-assisted technique. Balloon-assisted coil embolization using Equinox balloon, Commodore balloon, and Hyperform balloon were performed for four patients and stent-assisted coil embolization using BX velocity for one patient. We discuss problems of coil embolization for acutely ruptured wide-necked aneurysms with a balloon or stent-assisted technique.
