Surgical Repair of Dissecting Aortic Aneurysms(DeBakey IIIb) Presenting with Visceral Perfusion from the False Lumen / 日本心臓血管外科学会雑誌

ABSTRACT

We reviewed our experience with 4 cases of chronic dissecting aortic aneurysm (DeBakey IIIb) with the false lumen extending into the abdominal aorta and major branches being perfused from the false lumen. In such cases, resection of the intrathoracic portion of the aneurysm and closing of the distral false lumen may exclude visceral perfusion from the false lumen. In order to ensure continued perfusion of true and false lumens after repair, we performed “double barrel” anastomosis for distal anastomosis in graft replacement of the descending aorta. Follow-up periods ranged from 8 to 21 months, 17 months on average. Postoperatively, neither apparent expansion of the false lumen nor compression of the true lumen was found in these cases. The advantage of this procedure is the effective restoration of visceral perfusion. We emphasize that this procedure is one of the choices of procedures, as a two-staged approach for chronic aortic dissection presenting with visceral perfusion from the false lumen and without an enlarged abdominal aorta, though more patients and longer follow-up are required to fully evaluate this procedure.
