摘要
目的:探讨利用多层螺旋CT(multislice CT,MSCT)发现肝癌寄生动脉的方法及其在介入治疗中的意义. 方法:肝癌患者52例行MSCT双期增强扫描及化疗栓塞(TACE)治疗,动脉造影证实有60支寄生动脉,34例为首次治疗的患者,18例经多次介入治疗.回顾性研究寄生动脉及其供血肿瘤在MSCT上的表现及如何选择介入治疗程序. 结果:介入治疗前MSCT显示寄生动脉34支,阳性率为56.7%(34/60);多次复查时又显示13支,总阳性率为78.3% (47/60).13支未显示.寄生动脉供血的病灶均位于肝脏边缘,长径平均6.9±2.2 cm.在MSCT上,36例可见肿瘤侵犯附近组织或器官.呈纵行走向的寄生动脉(如膈下动脉、胸廓内动脉)易于在CT上显示,横行走向的寄生动脉不易显示. 结论:MSCT动脉期扫描可显示纵行走向的寄生动脉.介入治疗时,先寻找寄生动脉并经其行TACE,再经肝动脉途径TACE,可有效提高介入治疗的质量.
AIM: To diagnose extrahepatic feeding arteries of hepato-cellular carcinoma (HCC) in hepatic arterial phase multislice computerized tomography (MSCT) for interventional treatment. METHODS: Biphasic MSCT and transcatheter arterial chemoembolization (TACE) were performed in 52 patients with HCC, who were confirmed with 60 branches extrahepatic feeding arteries by arteriography, in which 34 were intial patients, 18 with multi-TACEs. According to the arteriography, the MSCT signs of feeding arteries and tumors were studied retrospectively. RESULTS: Before initial TACE, 34 branches extrahepatic feeding arteries (56.7%, 34/60) were displayed in 33 patients in arterial phase MSCT. Follow-up data showed that another 13 branches were displayed (78.3%, 47/60), and 13 branches were not displayed. All the tumors fed by extrahepatic arteries located in the margin of liver and its longitude was average 6.9±2.2 cm. The tumors conglutinated with the nearby organs and tissues in 36 cases. The displaying rate was higher in longitudinal position arteries (for example, inferior phrenic arteries, internal thoracic artery.), showed a 'dot' high density. In 33 branches feeding inferior phranic arteries, 21 branches were displayed as the source arteries. The displaying rate was lower in axial position arteries.
