15例肾血管平滑肌脂肪瘤行选择性肾动脉造影,2例表现为乏血管性肿瘤,13例见肿瘤血管增多和血管动脉瘤样扩张,并见界面清楚的低密度区;对其中13例施行超选择性肾动脉栓塞术,9/13例于栓塞后2～6天行肿瘤切除,取得了手术操作容易、减少出血的效果,无水乙醇中断血运优于明胶海绵;4/13例栓塞后未行手术,半年后 CT 复查见肿瘤缩小50%以上,一般可以一次完成诊断性造影及栓塞治疗。
Fifteen cases of renal angiomyolipoma underwent selective renal artery angiography, two cases showed lack of vascular tumors, thirteen cases of tumor angiogenesis and aneurysm-like dilatation, and the clear interface of low density area; of which 13 cases were administered Superselective renal artery embolization, 9/13 cases of tumor resection 2 to 6 days after embolization, made the operation easy to reduce the effect of bleeding, dehydration of ethanol is better than gelatin sponge interruption; 4/13 cases of embolism After no surgery, six months after the CT review found that the tumor is reduced by more than 50%, generally can be a diagnostic imaging and embolization.
