摘要

We describe the hemodynamic features and anatomic basis of false-negative Doppler sonographic findings compared with angiographic findings in a 42-year-old woman after orthotopic liver transplantation complicated by hepatic artery thrombosis. Complete common hepatic artery thrombosis was demonstrated by Doppler sonography and digital subtraction angiography (DSA) on the first postoperative day. A thrombectomy was performed. DSA on the third day after transplantation again showed occlusion of the left hepatic artery. No perfusion was observed in the left hepatic lobe. Liver function remained normal. Doppler sonography on days 8, 10, and 16 after transplantation demonstrated arterial blood flow in both the right and left lobes of the liver, suggesting patent left and right hepatic arteries. Repeat DSA revealed that the arterial flow in the left lobe depended on large, intrahepatic shunts originating from the right hepatic artery. Apparently, shunts can develop within a few days in a transplanted liver from radiologically undetectable structures into vessel-like channels capable of supplying the entire left hepatic lobe.
