动态增强CT扫描和肝动脉造影对原发性肝癌的诊断价值

对36例原发性肝癌进行了动态增强CT扫描和血管造影对照性研究,肝癌时间密度曲线峰值高且早于正常肝组织峰值10～15s,说明肝癌主要由肝动脉供血;还可增加肝静脉及门/腔静脉内瘤栓的检出率。而肝动脉血管造影对了解肿瘤血供来源、供血血管的多寡和经肝动脉导管做介入性治疗等。单从定性诊断和了解肿瘤与周围组织关系应选用动态增强CT扫描,而诊断与治疗并重则应选用血管造影,且该法可同时经导管灌注抗癌药和/或行栓塞治疗。

DIAGNOSTIC VALUE OF DYNAMIC ENHANCEMENT CT SCAN AND HEPATOARTERIOGRAPHY IN PRIMARY HEPATOCELLULAR CARCINOMA (HCC)

Thirty six cases primary hepatocellular carcinoma proved by surgical-pathology were studied by dynamic CT scan and selective hepatoarteriography. On dynamic enhancement CT imagines, HCC showned characteristics of hepatic arteriol blood supply based on the time-density curve line of tumors. CT could increase detectal rate of hepatoarterioportal venous shunts, hepatic veins or portal veins invasion, and falsecapsule of tumors. Hepatoartiography might find the oringin of bloodsupply vasculary, A-V shunts, a tumor stain, displacement of hepatic artery, hypervascu- lary and/or hypovasculary of the liver cancer. Evaluation was made of dynamic enhancement CT scan and hepatoarteriography in treatment planning of HCC. These findings suggest that hepa- toarteriography combined with anticancerous agent infusion and iodine oil embolization was se- lected interventional method to diagnosis and treatment of advanced HCC.
