Successful portosystemic shunt embolization resolves hepatic encephalopathy and enhances hepatic function and glycemic control in MASH-related cirrhosis: a case report.

Abstract

We report the case of a 70-year-old woman with advanced hepatic encephalopathy (HE) secondary to metabolic dysfunction-associated steatohepatitis (MASH)-related cirrhosis who exhibited an excellent response to portosystemic shunt embolization. Four years earlier, she was diagnosed as having MASH-related cirrhosis accompanied by multiple mesenteric vein-inferior vena cava shunts. As her condition progressed, she suffered recurrent HE that was unresponsive to oral medication, prompting the decision to proceed with shunt embolization. The procedure was successful, with no ensuing HE recurrence. At the 1-year follow-up, she remained free from refractory ascites, and no new shunts were detected. Remarkably, her liver function and glucose metabolism also showed significant improvement after the embolization. This case demonstrates that shunt embolization may be an effective treatment option for refractory HE associated with cirrhosis not only in terms of encephalopathy, but also for ameliorating hepatic function and glycemic control.
