- W2978973365 abstract "Introduction: Hepatoportal fistula is an arteriovenous communication between the splanchnic artery and the portal vein that can be either congenital (type 3) or acquired (type 1 small peripheral and type 2 large central). Type 1 is usually transient and asymptomatic, whereas type 2 can cause portal hypertension and its complications of variceal bleed or ascites. Herein, we present a case of type 2 hepatoportal fistula developing after liver biopsy and its management. Case Report: A 75-year-old woman with autoimmune hepatitis with overlap syndrome was seen at a follow-up visit. She underwent an ultrasound-guided left lobe liver biopsy 1 year ago for worsening liver enzymes. The biopsy was without complications. A routine ultrasound of the abdomen with color Doppler at this follow-up showed a moderate to large communication of the left hepatic artery with the left portal vein with reverse flow on color Doppler ultrasonography. Although the patient was asymptomatic, she was referred to interventional radiology for embolization due to the size of the fistula. Segment 2 of the left hepatic artery was successfully embolized using 0.3 cc 40% n-butyl-2-cyanoacrylate. A postembolization contrast study demonstrated elimination of fistula. The procedure was without complications and well tolerated. Discussion: Liver biopsy plays an important role in managing patients with chronic liver diseases. Type 2 hepatoportal fistula is a rare but serious complication from liver biopsy. This case demonstrated the importance of color Doppler ultrasonography in detection of hepatoportal fistula. Furthermore, preemptive treatment with radiological guided embolization can prevent development of portal hypertension and its complications.Figure 1: Hepatoportal fistula post embolization with n-butyl-2-cyanoacrylate." @default.
