DOPPLER IMAGING OF AN INADVERTENT ANASTOMOSIS OF MODIFIED BLALOCK-TAUSSIG SHUNT TO THE RIGHT UPPER PULMONARY VEIN

In a newborn infant with a complex congenital heart disease, a right m odified Blalock-Taussig anastomosis was created because of the pulmona ry atresia. A 4-mm Gore-Tex tube was inadvertently connected to the up per right pulmonary vein. Clinical signs of an arteriovenous fistula w ith no improvement in oxygen saturation were noticed immediately after surgery. This complication was confirmed by colour Doppler examinatio n and angiography. Reanastomosis of the tube to the right pulmonary ar tery was then performed.
