Ten-year experience of transjugular intrahepatic portosystemic shunt for noncirrhotic portal hypertension

摘要

BackgroundTransjugular intrahepatic portosystemic shunt (TIPS) is considered to be well suited for the treatment of noncirrhotic portal hypertension (NCPHT) because of a usually severe portal hypertension (PHT) and a mild liver failure, but very less data are available.Patients and methodsRecords of patients referred for TIPS between 2004 and 2015 for NCPHT were reviewed. No patient should have clinical or biological or histological features of cirrhosis.ResultsTwenty-five patients with a wide variety of histological lesions (sinusoidal dilatations, granulomatosis, regenerative nodular hyperplasia, obliterative portal venopathy, or subnormal liver) and a wide variety of associated diseases (thrombophilia, sarcoidosis, common variable immunodeficiency, scleroderma, Castleman's disease, early primitive biliary cirrhosis, congenital liver fibrosis, chemotherapy, purinethol intake, and congenital varices) were included. Two complications occurred during the procedure: one periprosthetic hematoma and the other misposition of a covered stent. During the first month, two other patients had an early thrombosis, another had induced encephalopathy, and one died of early rebleeding. Two of these complications occurred in patients with cavernoma. With a mean follow-up of 39 months, 10 patients experienced at least one episode of spontaneous encephalopathy, with three of these patients requiring a stent reduction. Five patients had a recurrence of their initial symptoms, and one had an asymptomatic hemodynamic dysfunction.ConclusionTIPS is effective in NCPHT but can be technically difficult, especially in the case of cavernoma. Good liver function does not prevent the occurrence of long-term encephalopathy.
