目的　评价螺旋CT经动脉门静脉造影 (SCTAP)对肝癌可手术切除治疗的临床应用价值。方法　 2 3例肝内病变 (包括肝癌 2 1例 )采用SCTAP、常规CT及DSA检查 ,比较三者显示病灶个数的差异性及敏感性。结果　SCTAP对显示 <3 0mm及<10mm病灶数与常规CT及DSA比较有显著性差异 (Ρ <0 .0 1及Ρ <0 .0 5 ) ,对 >3 0mm病灶的显示 ,无显著性差异 (Ρ >0 .0 5 )。2 1例肝癌患者中 9例SCTAP未发现肝内转移灶而选择手术治疗 ,12例SCTAP发现肝内多个转移灶而选择介入经肝动脉化疗栓塞 (TACE)治疗。结论　SCTAP显示小肝癌微小肝癌或微小转移灶与常规CT、DSA比较具有极高的敏感性 ,对判断肝癌能否手术切除治疗有较大的临床应用价值。 Objective To evaluate the clinical value of spiral CT in the surgical resection of hepatocellular carcinoma treated by arterial portal venography (SCTAP). Methods Twenty-three cases of intrahepatic lesions (including 21 cases of hepatocellular carcinoma) were examined by SCTAP, routine CT and DSA. The differences and sensitivities of the three lesions were compared. Results SCTAP showed that the number of lesions <3 0mm and <10mm was significantly different from that of conventional CT and DSA (P <0 01 and Ρ 0 05), but no significant difference was found for> 3 0mm lesions (Ρ> 0 .0 5). Twenty-five patients with hepatocellular carcinoma (SCTAP) were treated by transcatheter arterial chemoembolization (TACE) without any intrahepatic metastases (SCTAP). Nine of 12 patients with SCTAP were found to have multiple intrahepatic metastases. Conclusion SCTAP shows that small hepatocellular carcinoma or micrometastasis has a very high sensitivity compared with conventional CT and DSA. It has great clinical value in judging whether hepatocellular carcinoma can be surgically removed.
