His family history and the results of a physical examination were highly suggestive of Osler-Weber-Rendu disease (hereditary hemorrhagic telangiectasia, HHT). Cardiac catheterization and hepatic angiography demonstrated HHT with left-to-right shunting from the liver. The patient underwent transcatheter arterial embolization (TAE) of the right hepatic artery. We performed both Doppler sonography and angiography before and after TAE. The treatment improved the clinical manifestations of congestive heart failure, including the edema of the leg and dyspnea. Doppler sonographic studies also showed an increased resistive index in the right hepatic artery and decreased flow volumes and velocities in the right and middle hepatic veins, respectively, after treatment. Corresponding changes on angiography after TAE showed decreased right hepatic arterial flow and nonopacified branches distal to the coils, disappearance of the mottled hepatogram in the right lobe, reduction of contrast agent staining, and enhanced calibers in the right and middle hepatic veins. This case illustrates that qualitative and quantitative studies with duplex and color Doppler ultrasound can be used to detect or define the extent of hepatic involvement in HHT patients before TAE, monitor hemodynamic changes of the intrahepatic vasculature after TAE, evaluate the efficacy of treatment, and possibly obviate the need for repeated angiography for diagnosis only. |
