ABSTRACT
Extrahepatic portal vein thrombosis (EHPVO) is an uncommon cause of portal hypertension. In the long term, patients may develop portal cavernoma cholangiopathy (PCC). Up to 30%-40% of patients with EHPVO may not have shuntable veins and are often difficult to manage surgically. Interventional treatment including portal vein recanalisation-trans jugular intrahepatic portosystemic shunt (PVRecan-TIPS) has been used for patients with EHPVO. However, PV reconstruction-trans jugular intrahepatic portosystemic shunt (PVRecon-TIPS) and portal vein stenting are novel techniques for managing such patients with EHPVO with non-shuntable venous anatomy. In contrast to PVRecan-TIPS, PV reconstruction-TIPS (PVRecon-TIPS) is performed through intrahepatic collaterals. Here we present six cases of PCC who presented with recurrent acute variceal bleeding (AVB) and or refractory biliary stricture. They did not have any shuntable veins. PVRecon-TIPS was performed for five patients whilst PV stenting was done in one. Amongst the six patients, one died of sepsis whilst one who developed hyponatremia and hepatic encephalopathy was salvaged with conservative management. Following the procedure, they were started on anti-coagulation. Decompression of cavernoma was documented in all other patients. Biliary changes improved completely in 40% of patients.
