UNIFOCALIZATION OF MAJOR AORTOPULMONARY COLLATERAL ARTERIES IN PULMONARY ATRESIA AND VENTRICULAR SEPTAL-DEFECT USING ANTIBIOTIC STERILIZED PULMONARY HOMOGRAFT - A CASE-REPORT

A unifocalization procedure in a 9-year-old girl with pulmonary atresi a, ventricular septal defect, and major aortopulmonary collateral arte ries (MAPCAs) was performed using an antibiotic sterilized pulmonary h omograft. A tailored pulmonary homograft was used as an interposition graft to anastomose the pulmonary artery to the larger MAPCA after a s ide-to-side anastomosis had been done between the two MAPCAs. The pulm onary homograft was connected to the right subclavian artery with a 6- mm Gore-Tex shunt. Postoperative oxygen saturation (SaO2) levels were satisfactory and a postoperative angiogram showed good unifocalization of the pulmonary vasculature.
