摘要
目的探讨胃左动脉在原发性肝癌供血中的影像学特点及其在介入治疗中的意义;方法回顾性分析2012年6月至2015年6月553例接受介入治疗的原发性肝癌患者的血管造影资料及临床资料,分析胃左动脉参与肝癌供血的影像学特征及介入治疗经过。结果 553例患者中66例中发现胃左动脉分支参与肝癌供血,发生率为11.9%,主要供应位于肝左叶的病灶,其中80.3%患者在第1次介入治疗中发现此种表现,其中86.3%为富血供肝癌;栓塞成功率为92.4%。未发生异位栓塞。结论胃左动脉发出的副肝左动脉是肝癌重要的侧支供血动脉之一,治疗中需注意造影技巧,仔细寻找,提高病灶的栓塞效果。
Objective To investigate the imaging features of left gastric artery that is involved in the blood supply of primary hepatocellular carcinoma（PHC） and to discuss its significance in interventional therapy. Methods The angiographic findings and the clinical data of 553 PHC patients, who were admitted to authors＇ hospital to receive interventional therapy during the period from June 2012 to June 2015, were retrospectively analyzed. The imaging features of left gastric artery that was involved in the blood supply of PHC were analyzed, and its significance in the interventional therapy of PHC was discussed. Results In 66 of 553 patients, the branches of left gastric artery participated in the blood supply of PHC, the incidence of participation in blood supply was 11.93%. The branches of the left gastric artery mainly provided blood supply to the lesions located at left lobe of liver, this imaging manifestation was detected at initial interventional therapy in 80.3% of patients, and PHC with rich blood supply was found in 86.3% of them. Successful embolization was achieved in 92.4% of PHC lesions. No extra-gastric ectopic embolism occurred. Conclusion The accessory left hepatic artery originated from left gastric artery is one of the important collateral feeding arteries of PHC. In performing interventional therapeutic procedure for PHC, the angiography technique should be taken into consideration, and the possible blood supply arteries of PHC should be carefully searched for so as to improve the embolization effect of PHC lesions.
