目的研究创伤性肾出血在保守治疗无效情况下进行动脉栓塞的造影表现及栓塞方法。方法采用超选择性肾动脉栓塞术治疗25例肾损伤患者,所有病人在栓塞前都进行肾动脉造影证实诊断。栓塞材料用明胶海绵加金属钢圈。结果24例病人经栓塞后,临床症状很快得到缓解,1个月后进行静脉尿路造影检查,伤侧肾功能恢复。1例栓塞后仍持续性血尿行肾切除。结论对创伤性肾出血病人,采用肾功脉栓塞具有止血效果好、能最大限度保护肾功能、减少并发症,是一种治疗肾损伤的安全有效方法。
Objective To study the angiographic manifestations and embolization of arterial embolism in patients with traumatic renal hemorrhage who are ineffective in conservative treatment. Methods 25 patients with renal injury were treated with superselective renal artery embolization. All patients were confirmed by renal artery angiography before embolization. Embolization material with gelatin sponge plus metal rims. Results After the embolization of 24 patients, the clinical symptoms were quickly relieved. One month later, intravenous urography was performed and the injured side of the kidney was recovered. One case of persistent hematuria underwent nephrectomy after embolization. Conclusion For patients with traumatic renal hemorrhage, the use of renal artery embolization has a good hemostatic effect, can maximize renal function and reduce complications, is a safe and effective method of treatment of renal injury.
