Abstract:
A new method of revascularization of digestive and renal arteries is reported in this paper, accomplished through the intra-aortic or ostial root, in a 53-year old woman, with the diagnosis of thrombotic occlusion of the terminal aorta associated to a protuberant and calcified lesion of the supraceliac aorta ("coral reef"). The procedure consisted in the implantation of a bifurcated prosthesis from the descending thoracic aorta to both common iliac arteries, through the diaphragm, followed by a longitudinal aortotomy aimed at the removal of the "coral reef" lesion and revascularization of renal, mesenteric and celiac arteries, by means of additional prosthesis placed between the bypass graft and the ostia of these arteries. The left renal artery was reattached to the bypass graft. Visceral ischemic times were short. The post operative course was uneventfull. Two months later, an angio-CT disclosed the complex procedure of revascularization working in excellent condition. The advantages of this new method of revascularization of abdominal visceral arteries in complex obstructive aortic pathology are analysed and discussed.
