title: Modified Blalock shunts utilizing pericardial tube grafts.
abstract: In the last decade, 14 patients underwent an aorticpulmonary shunt for cyanotic heart disease, at which time the subclavian artery was either deemed too small or too short to function satisfactorily as a Blalock shunt. In each case a rectangular piece of pericardium was excised, rolled into a tube, and sutured down one edge to create a tube graft. One end of the graft was sutured to the stump of the subclavian artery near its takeoff and the other end was sutured end-to-side to the corresponding pulmonary artery. During the same period, 5 children had azygos vein grafts and 2 had Teflon grafts inserted to create a modified Blalock shunt. This article will discuss the indications, techniques, and long term results of aorticpulmonary shunts of all types, and more specifically the complications and long term results in patients where these grafts were used.
