Diagnostic value of DSA for micro hepatocelluar carcinoma in patients with hepatic cirrhosis / 介入放射学杂志

ABSTRACT

Objective To investigate the diagnostic value of DSA for micro hepatocelluar carcinoma(MHCC)in patients with hepatic cirrhosis. Methods Three hundred and fourty cases of hepatic cirrhosis who were going to receive bone marrow stem cells transplantation via hepatic artery underwent hepatic arterial DSA. No definite evidence of hepatoma had been found during the former CT scan and ultrasound test in these patients. Multi-angle projection DSA was performed to display the characteristics of MHCC and super-selective TACE treatment was given in cases of the diagnosed MHCC. Results MHCC were found by DSA in 20 cases who were all of post-hepatitis B cirrhosis and with single-lesion of sized 0.4 - 1.0 cm. DSA showed the characteristics of nodular stains in early or middle arterial phase in angiography. 18 lesions were in the right lobe and 2 in the left lobe. AFP were negative in 16 cases and positive in 4 cases. Super-selective segmental TACE were performed with micro catheter system for the treatment. Conclusions DSA is more sensitive to detect MHCC in the patients with hepatic cirrhosis, comparing with regular contrasted CT scan or ultrasound.
