Purpose: To evaluate the efficacy of color and pulsed Doppler ultrasound (US) for the
detection of arterial revascularization of hepatocellular carcinoma (HCC) after
transcatheter arterial chemoemblization (TACE).
Materials and Methods : One hundred and four histologically proven HCCs(0.7-12.5cm,
mean 4.14cm) of 87 consecutive patients who had undergone TACE using a
Lipiodol-chemoagent suspension were examined using color Doppler equipment. The
criteria for diagnosing arterial revascularization of HCC were detection of inward blood
vessels within HCC and demonstration by spectral Doppler US of pulsatile arterial flow
within the vessel. Color Doppler US was prospectively performed using a multi-Hertz
probe (2.5-5Hz), and was followed by digital subtraction angiography(DSA).
Results : In 37 of 104 HCCs in 87 patients treated with TACE, color and spectral
Doppler US demonstrated intratumoral arterial flows, with peak systolic velocity of
4.2-220 (mean, 59) cm/sec. DSA revealed neovascularity or tumor stains in 38 HCCs
(3.4-12.5 cm, mean 5.9 cm in size) including 37 which on Doppler US showed arterial
flow. The remaining 66 of 104 HCCs(0.7-6.3 cm, mean 3.2 cm) did not stain during
DSA. Doppler US showed a false negative result in only one HCC(4.6 cm, located at
segment ¥· of the Couinaud classification), which stained faintly during DSA. The
sensitivity speciricity, and accuracy of color and spectral Doppler US used for the
detection of recurrent HCC were 97.4%, 100%, and 99%, respectively.
Conclusions : Color and spectral Doppler US is an effective method for the evaluation of
arterial revascularization of HCC after TACE.
