Comparative Study
Colonic ischemia complicating open vs endovascular abdominal aortic aneurysm repair.
Colonic ischemia (CI) is a known complication of both open abdominal aortic aneurysm (AAA) repair and endovascular aneurysm repair (EVAR). Despite a relatively low incidence of 1% to 6%, the associated morbidity and mortality are high. We sought to analyze factors that affect the development of CI on the basis of type of repair as well as associated outcomes from a large nationwide database. ⋯ CI is significantly more common after open AAA repair and is associated with increased morbidity and a two- to fourfold increase in mortality.

Stenosis of the cephalad internal carotid artery (ICA) can present a challenge, making it difficult to obtain a technically satisfying distal end point during endarterectomy. Surgical revision of distal defects can be difficult and yield unsatisfactory results. The purpose of this review is to evaluate the efficacy of intraoperative carotid stenting as an adjunct to endarterectomy to salvage technical defects identified at the cephalad ICA endarterectomy site. ⋯ Intraoperative salvage carotid stenting is an effective and safe adjunct to endarterectomy when unsatisfactory technical defects are identified at the cephalad ICA endarterectomy site.
