Case Report: Portal Vein Thrombosis, Surgical Alternatives in Liver Transplantation.

INTRODUCTION

Liver transplant remains a surgical challenge in cases of portal vein thrombosis. Ten percent of patients listed for liver transplant have this diagnosis preoperatively. Although several techniques of portal revascularization are available, sometimes the best result is not achieved, depending on the extent of thrombosis.

OBJECTIVE

The aim of this article is to report our experience in 2 particular cases of liver transplant with portal vein thrombosis.

MATERIAL AND

METHODS

We present the cases of 2 patients with partial portal thrombosis that extended to the porto-spleno-mesenteric system. The first case is a 36-year-old woman with recurrence of autoimmune liver disease requiring a second graft; the second case concerns a 64-year-old man with alcoholic liver cirrhosis.

RESULTS

Both patients had a splenorenal shunt. A portal bypass with a Y venous graft was performed using the cavoiliac veins of the donor. The anastomosis was performed to the superior mesenteric and left renal veins.

DISCUSSION AND

CONCLUSIONS

These clinical cases demonstrate that portal vein thrombosis is not an absolute contraindication for transplantation and that surgical alternatives exist in cases of grade III portal vein thrombosis.
