Persistent left superior vena cava draining into the left atrium associated with the atrial septal defect and partial anomalous pulmonary venous drainage: surgical correction with sepcially designed prosthetic material.

Anomalous drainage of the persistent left superior vena cava into the left atrium with partial anomalous pulmonary venous return and the atrial septal defect is relatively rare condition, and there reported various kinds of surgical procedures in correction for this lesion. This report describes the original and simple surgical procedure in total correction of these lesions performed in our institute, using a large Dacron patch connected with a knitted Dacron vascular graft in its center. Surgical correction was accomplished by anastomosis of a Dacron draft with the orfice of the persistent left superior vena cava into the left atrium, widening of the atrial septal defect, and reconstruction of a new atrial septum with a Dacron patch. Postoperative cardiac evaluation revealed good condition of blood stream through a Dacron draft from the left superior vena cava to the right atrium, with corrected pulmonary venous drainage into the left atrium without pulmonary venous congestion and superior vena cava syndrome.
