[Arterioportal fistula as a result of percutaneous transhepatic catheterization of the portal vein].

In 93 patients who underwent percutaneous transhepatic portography an arteriography of the liver was performed. In 8 cases intrahepatic arterioportal fistulas of iatrogenic descent were found. All 8 patients suffered from liver cirrhosis. There were no remarkable clinical symptoms. Artificial arterioportal fistulas showed a tendency spontaneous occlusion. For their detection the length of the interval between percutaneous transhepatic portography and hepatic arteriography is important. In 7 patients with iatrogenic arterioportal fistulas an embolization of the trunk or the right liver artery was carried out. This therapy turned out to be effective.
