JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Percutaneous Transparaumbilical Embolization of Spontaneous Portosystemic Shunts for the Treatment of Hepatic Encephalopathy

Ho Young Park, MD, Jiaywei Tsauo, MD, Ji Hoon Shin, MD, Pyeong Hwa Kim, MD

The medical records of 7 patients who underwent percutaneous transparaumbilical embolization of spontaneous portosystemic shunts for treatment of hepatic encephalopathy (HE) were retrospectively reviewed. Technical success was achieved in 100% (7/7) of patients. Four patients had complete resolution and 3 had improvement of signs and symptoms of HE within 3 days after the procedure for a clinical success rate of 100% (7/7). New-onset esophageal varices, a major complication, occurred in 1 patient. No other major complications were encountered. HE recurred in 71.4% (5/7) of patients during a median follow-up period of 43 months (range, 4–111 months).
