Use of the ascending aorta as bypass inflow for treatment of chronic intestinal ischemia

Antegrade intestinal artery bypass from the ascending aorta is an effective alternative for patients who have no other available inflow for conventional antegrade or retrograde bypass and for patients in whom major technical difficulties are likely after multiple exposures of the thoracoabdominal aorta. Although indications are uncommon, antegrade intestinal artery bypass can provide durable revascularization of the intestine.
