Surgical Correction of Obstruction of the Inferior Vena Cava using Profound Hypothermia and Total Circulatory Arrest

Abstract
|
|
|
Membranous obstruction of the inferior vena cava(IVC) is a rare congenital anomaly that may present clinical features of Budd-Chiari syndrome caused by chronic obstruction of hepatic drain.
We have experienced a case of I VC obstruction caused by hour-glass constriction and membrane in its center.
Operative correction was accomplished using profound hypothermia (201C) and total circulatory arrest of 26 minutes. This technique permitted resection of membrane with direct vision and removal of thrombus of I VC and hepatic vein. After then constricted I VC was repaired with autologous pericardial patch. Total circulatory arrest was used intermittently for good visual field.
Postoperative course was smooth and postoperative angiography showed unobstructed flow through the IVC in spite of slight constriction of cavoatrial junction and nearly complete disappearance of collateral vessels.
