目的 :观察以白芨为栓塞材料对肾错构瘤行超选择性栓塞的治疗效果。方法 :对 5例经 CT、B超确诊为肾错构瘤的患者行白芨粘胶剂栓塞 ,栓塞后每 3个月作 B超复查 ,每半年行 CT复查 ,比较肿瘤的变化以及症状改善的情况。随访 2～ 4年。结果 :临床症状术后均有不同程度减轻或消失 ,肿瘤缩小的百分率为 5 2 %～ 75 % ,平均为 6 4% ;肿瘤有液化但呈分隔片状 ,未融合成巨大囊肿 ,所有患者未出现严重并发症。结论 :对不能采用剜除术或肾部分切除术、特别是对侧肾亦有肿瘤和病变的肾错构瘤患者 ,应首先考虑作超选择性栓塞治疗。白芨作为栓塞材料引起的并发症少 ,且兼有抗感染、抗肿瘤和促进凝血的功能 ,值得进一步研究和推广应用 OBJECTIVE: To observe the curative effect of transcatheter embolization of renal hamartoma with embolic material as embolic material. Methods: Five patients diagnosed as renal hamartoma by CT and B ultrasound underwent embolization of Baijiao adhesive. After embolization, B-ultrasound was performed every 3 months. CT scan was performed every six months to compare the changes of tumor and the improvement of symptoms Happening. Follow-up 2 to 4 years. Results: The clinical symptoms were relieved or disappeared to varying degrees after operation. The percentage of tumor shrinkage was 52% -75%, with an average of 64%. The tumor was liquefied but separated into flake and unmalgmented into giant cysts. All the patients did not A serious complication occurred. CONCLUSIONS: Patients with renal hamartoma who can not be treated with nephrectomy or partial nephrectomy, especially those with tumors and lesions of the contralateral kidney, should be considered for the first time as superselective embolization. Bletilla striatum as a material caused less complications, and both anti-infective, anti-tumor and promote coagulation, worth further study and promote the use of
