title: Duplex pulsed Doppler sonography of hepatocellular carcinoma treated with transcatheter arterial embolization.
abstract: Thirty-one patients with hepatocellular carcinoma underwent duplex scanning of their lesions with comparative angiography and serum alpha-fetoprotein determinations before and after transcatheter arterial embolization. Duplex ultrasound correctly identified 26 patients with patent tumor vessels after embolization. The Doppler signals became undetectable after embolization in the other five patients. Comparative angiography demonstrated good devascularization of their lesions. However, tiny tumor blush or small satellite nodules around the periphery of the devascularized masses were found. Therefore, the presence of signals after therapy indubitably needs further embolization. The timing of the second embolization for the patient with undetectable Doppler signals after the first embolization needs to be justified by further evaluations.
