Transcatheter embolization of hypogastric artery aneurysms: lessons learned.
Transcatheter embolization of hypogastric artery aneurysms has become an attractive therapeutic alternative for many patients with this difficult lesion. Because of the increasing use of stent grafting for treatment of abdominal aortic aneurysms, transcatheter embolization of normal-caliber hypogastric arteries has become an almost routine procedure, usually accomplished with little morbidity. Applying this treatment to aneurysmal hypogastric arteries, however, involves greater technical complexity and a significantly higher risk of ischemic complications. We present three cases to illustrate the technical challenges of hypogastric aneurysm embolization, the potentially devastating ischemic complications, and the clinical situations that may predispose to poor outcomes.
