Abstract

The management of an ICMVP is complex and carries a high risk for severe potential complications. Two different pathophysiological mechanisms have been discussed in the literature, including gradual erosion into an adjacent vein and transvenous catheter placement of the initial shunt secondary to subcostal placement of shunt tunneling instruments. The suction effect of the venous system results in gradual pulling of the catheter into the venous system.
