肝外动脉为主要供血的肝细胞性肝癌的DSA表现及栓塞治疗探讨

目的 探讨肝外动脉供血肝细胞癌的DSA表现及栓塞治疗.方法 同颐性分析本中心2002年8月～2008年9月3例肝外动脉供血肝细胞肝癌患者的临床资料,包括患者的供血动脉形态、手术方式及时间、肝癌DSA表现及预后.结果 DSA显示3例患者肝癌动脉均存在解剖变异：1例患者肝外动脉直接开口于腹主动脉较高部位;2例患者肝外动脉与肾上腺中动脉共干开口于主动脉弓右外侧壁;3例患者肝外动脉均供血肝S6肿瘤,栓塞治疗后,无并发症,3例患者均存活6个月以上.结论 生理变异的肝外动脉可供血肝细胞性肝癌,其影像学诊断可靠,栓塞治疗疗效较好.

Imaging and embolization of hepatocellular carcinoma supplied by gonadal artery

Objective To evaluate radiology and embolization for hepatocellular carcinoma supplied by gonadal artery. Methods The medical records of 3 patients with hepatocellular carcinoma supplied by gonadal artery from August 2002 to September 2008 were reviewed. The de- mogTaphy, gonadal artery location, modus operandi, imaging features of liver cancer and prognosis were retrospectively analyzed. Results Anatomic variation of gonadal artery occurred with the gonadal artery arising from the upper abdominal aorta in 1 patient and from the middle suprarenal artery in 2 patients. The blood supply of the hepatocellular carcinoma derived from the gonadal artery in all 3 patients. No complications occurred in the 6-month follow-up after embolization. Conclusion Hepatocellular carcinoma may he supplied by gonadal artery, with anomalous origin, This anatomic variant can be readily demonstrated by imaging to guide embolization.
