Semiautologous repair for congenital discontinuous right pulmonary artery.

Unilateral absence of a proximal pulmonary artery (UAPA) is rare and occurs in an isolated form or in the presence of other cardiovascular anomalies. There is a paucity of literature describing surgical correction of this anomaly. Most commonly, a primary anastomosis between the main and proximal right pulmonary arteries has been described. However, in cases of long-gap discontinuity, this can be difficult and may result in excess tension on the anastomosis, predisposing to decreased patency. We present a novel technique by which discontinuity in the right pulmonary artery (RPA) is surgically corrected in a semiautologous fashion using a main pulmonary artery (MPA) flap.
