Abstract

BACKGROUND

Portal vein thrombosis (PVT) is a frequent complication occurring in 5% to 26% of cirrhotic patients candidates for liver transplantation (LT). In cases of extensive portal and or mesenteric vein thrombosis, complex vascular reconstruction of the portal inflow may become necessary for a successful orthotopic LT (OLT).

CASE SUMMARY

A 54-year-old male with history of cirrhosis secondary to schistosomiasis complicated with extensive portal and mesenteric vein thrombosis and severe portal hypertension who underwent OLT with portal vein-left gastric vein anastomosis.

CONCLUSION

We review the various types of PVT, the portal venous inflow reconstruction techniques.

Keywords: Portal vein thrombosis; Portal inflow reconstruction; Orthotopic liver transplantation; Splanchnic varices; Left gastric varix; Case report

Core Tip: The portal vein-variceal anastomosis is a challenging physiological non-anatomical technique of portal vein inflow reconstruction used and described rarely. Herein we review the various types of portal vein thrombosis, the portal venous inflow reconstruction techniques and describe an extraordinary case of portal vein-left gastric vein anastomosis for the portal inflow reconstruction during orthotopic liver transplantation.
