MULTIPLE ANOMALIES OF CAVAL VEINS IN A PATIENT WITH PULMONIC STENOSIS

Anomalies of the supra-diaphragmatic portion of the inferior caval vei n are rare in patients with normal situs. We recently encountered a pa tient with situs solitus and infundibular pulmonic stenosis who had bi furcation of the supradiaphramatic portion of the inferior caval vein with anomalous high insertion of one portion into the mid-right atrium . The other division joined the coronary sinus which also received a p ersistent left superior caval vein and left hepatic veins. Biplane ang iography was used to delineate the anatomy. Pre-operative delineation is required as this anomaly complicates cardio-pulmonary bypass.
