Modified Yasui Operation Using Cryopreserved Femoral Vein Homograft.

Abstract

The Yasui operation is indicated in an interrupted aortic arch and a posterior malaligned ventricular septal defect with a narrow subaortic region. We present a modification of the Yasui procedure in which the aortic reconstruction was simplified using a nonvalved cryopreserved femoral vein homograft to connect the pulmonary artery to the descending aorta. A side-to-side anastomosis was performed between the femoral vein homograft and ascending aorta to complete the neoaortic reconstruction. After baffling the left ventricle to the pulmonary artery with a patch, a valved segment from the same femoral vein homograft was used to restore continuity of the right ventricular outflow.
