Dorsal Cavoatrial Bypass for Segmental Obstruction of IVC -Report of 2 cases-
|
|

Abstract
|
|
|
Two patients with chronic Budd-Chiari syndrome resulting from segmental obstruction of the inferior vena cava underwent operation. There were 1 man and 1 woman. The obstructed segment was directly visualized by a transthoracic,
transdiaphragmatic,
retroperitoneal approach. In these two cases, severe segmental obstruction of the inferior vena cave was observed just above the right hepatic vein. These patients underwent successful retrohepatic cavoatrial bypass with a
polytetrafloroethylene(PTFE)
graft(16mm plain and 16mm ringed graft). There were no operative mortality and postoperative complication. These patients have been followed up for 6 months and 36 months without evidence of re-obstruction. When there is a severe stricture of the
IVC
with hepatic veins draining freely into the obstructed segment of the IVC, a dorsal cavoatrial bypass with a PTFE graft, preferably ringed, is the method of choice. (Korean J Thoracic Cardiovas Surg 1993;26:950-4)
