Abstract Purpose:To evaluate the efficacy of seletive renal-artery embolization in symptomatic renal angiomyolipoma (AML) with chinese medicine-bletilla striata as a vascular embolization agent.Methods:5 patients with symptomatic AMLS,1 male,4 female with a mean age of 55,underwent selective renal-arterial embolizations.Before embolization the diagnosis were confirmed by US and CT.After embolization, follow-up was made in all patients for 2～4 years.Results:The clinical symptoms in all 5 patients disappeared or relieved in different degrees.The shrink of tumor mass reached 52% to 75%, with a mean percentage of 64% at 24～48 months. CT follow-up showed liquefactive necrosis in all 5 embolized tumors ,which was distributed as separate smaller areas, but no large cystic lesion found. No severe late complications found. Conclusions:Selective renal-artery embolization should be considered as a primary theraputic modality for multiple angiomyolipomas or a very large one in a kidney, which can′t be removed by partial nephrectomy or enucleation. Bletilla Striata,as an embolization agent should be studied furtherly and applied widely.

随着诊断技术和介入放射技术的发展，肾错构瘤(angiomyolipoma of kidney,AML)可经CT、MRI和超声确诊，并采用选择性肾动脉栓塞术治疗。为了评价栓塞治疗的临床疗效，笔者对1993年6月～1999年6月收治的5例患者资料进行回顾性研究，现报告如下。
