摘要
目的探讨DSA对肝硬化并发微小肝癌(MHCC)的诊断价值。方法340例肝硬化患者,腹部增强CT及B超检查未见肝脏占位病变,在经肝动脉自体骨髓干细胞移植术前行肝动脉DSA,多角度投照,对造影发现的MHCC用微导管行肝段TACE治疗。结果DSA检查诊断MHCC20例。病灶均为单发,直径0.4~1.0cm,DSA表现为肝动脉造影早期至中期出现边缘较清楚的结节状染色,染色持续时间15s以上。病灶分布在左叶2例,右叶18例。AFP阳性4例,阴性16例。TACE治疗1次11例,2次7例,3次2例。栓塞后均见病灶内碘油聚集。1例TACE治疗1次后手术切除,病理证实为肝细胞癌。结论DSA对肝硬化并发MHCC的检出能力优于常规增强CT及B超检查。
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. Muhi-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-hepatitls B cirrhosis and with single-lesion of sized 0.4 - 1.0 em. 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 uhrasound.
