摘要
目的对原发性肝癌肝动脉化疗栓塞术(TACE)前行螺旋CT(SCT)平扫及增强双期扫描,结合术中血管造影,了解肿瘤存活区血供变化。方法对肝癌诊断明确,瘤体大小5～10cm,碘油沉积良好,在6个月内行3次TACE术,并在每次术前行螺旋CT平扫加增强双期扫描的27例患者进行肿瘤区血供分析。结果根据SCT表现将肿瘤存活区血供分为3种类型:肝动脉供血型、肝动脉及门静脉双重供血型、少血供型。结论原发性肝癌经TACE术后肿瘤存活区血供以肝动脉为主,肝动脉、门静脉双重供血及少血供较少,但随着TACE次数的增加,肿瘤存活区血供也发生了一定的改变,即门静脉参与肿瘤区血供的数量增加。
Objective To comprehend the changing of the blood supply in viable tumor area of hepatocellular carcinoma before transeatheter arterial chemoembolization （TACE） using dual-phase spiral computed tomography （SCT） scanning and digital subtraction angiography （DSA） during operation. Methods To analyze the blood supply in viable tumor area of 27 hepatocellular carcinoma patients whose tumor body were 5 - 10 cm large and lipiodol deposition is good, besides these patients have had three TACE during six months, and used SCT plain and enhanced scanning before TACE. Results Based on the performance of spiral dynamic enhanced scanning, the blood supply in viable tumor area was classified into three types： arterial blood supply, arterial together with portal blood supply and poor blood supply. Conclusion After TACE, arterial blood supply and arterial together with portal blood supply are the two main types of the blood supply in viable tumor aera. With TACE increased, the attribution of portal venous blood supply to viable tumor area was increased.
