Abstract
BACKGROUND

A congenital intrahepatic portosystemic shunt (IPSVS) is a rare vascular abnormality that is characterized by an anomalous intrahepatic venous tract that connects the intrahepatic portal vein with the hepatic venous system. Hepatic encephalopathy is an indication for IPSVS embolization, which is technically challenging because rapid blood flow through shunts can induce the migration of embolization material to systemic veins. This case report discusses the efficacy of percutaneous balloon-occluded retrograde transvenous obliteration for treating patients with IPSVSs.

CASE SUMMARY

A 75-year-old woman presented with a six-month history of repeated hepatic encephalopathy due to an IPSVS without liver cirrhosis. We successfully embolized the IPSVS using percutaneous balloon-occluded retrograde transvenous obliteration with interlocking detachable coils. After the procedure, the patient exhibited no symptoms of hepatic encephalopathy for 14 mo.

CONCLUSION

Balloon-occluded retrograde transvenous obliteration with detachable coils can be effective for the endovascular treatment of an IPSVS.

Core Tip: Portosystemic venous shunts are generally formed in patients with hepatic fibrosis and cirrhosis due to portal hypertension. Adult cases of congenital intrahepatic portosystemic shunt (IPSVS) are extremely rare. Hepatic encephalopathy is an indication for IPSVS embolization. Minimally invasive treatments that use interventional techniques, such as transcatheter embolization, are being utilized increasingly recently; however, shunt embolization is technically challenging because rapid blood flow through shunts can induce the migration of embolization material to systemic veins. Balloon-occluded retrograde transvenous obliteration with detachable coils can be effective for the endovascular treatment of an IPSVS.
