We performed ultrasound guided liver biopsy on 109 patients with chronic hepatitis from April 1996 until August 1997. We observed the needle tracts leading to the surface of the liver in all patient and found abnormal color Doppler flow in 16 of them. Waveform was constant in 11 of these cases and pulsatile in 1 case, in the remaining 4 cases, it could not be analyzed. We divided the 16 cases into two groups based on presence or absence of residual needle tract one minute after liver biopsy. One group (6 cases) retained the residual tract in the liver; the other group (10 cases) did not. Comparison of the backgrounds of the patients in the two groups showed the only significant difference to be in the results of the normotest. The tract disappeared in the 6 cases in which it had been retained, when pure ethanol was injected into the residual tract through a PTC needle. We suggest that color Doppler ultrasonography may prove useful for the prediction of bleeding after liver biopsy, and that percutaneous ethanol injection may be effective in stopping bleeding after this procedure.
