目的：研究肾动脉栓塞术在肾肿瘤术前和肾血管畸形出血病人中的临床应用。方法：对１６例进行选择性肾动脉栓塞，其中１４例肾肿瘤为术前栓塞，应用明胶海绵碎屑，栓塞程度达肾动脉主干。２例肾动静脉血管畸形出血，采用２ｃｍ长丝线段加明胶海绵碎屑行肾亚段栓塞。结果：（１）术中易剥离，出血少。（２）术野清晰，缩短术时。（３）肾血管畸形者，止血效果显著，并能免于剖腹手术，且不影响患肾功能。结论：选择性血管造影可以鉴别肾良、恶性病变，为肾切除及止血栓塞提供依据。
Objective: To study the clinical application of renal artery embolization in preoperative renal tumor and renal vascular malformations. Methods: Selective renal artery embolization was performed in 16 cases. Among them, 14 cases of renal tumors were preoperatively embolized with gelatin sponge and embolization of the renal artery. 2 cases of renal arteriovenous malformations hemorrhage, using 2cm filament segments plus gelatin sponge debris renal sub-segment embolization. Results: (1) intraoperative peel easily, less bleeding. (2) surgical field is clear, shorten the operation time. (3) Renal vascular malformation, hemostatic effect is significant, and can be avoided from laparotomy, and does not affect the function of the kidney. Conclusion: Selective angiography can identify benign and malignant renal lesions and provide the basis for nephrectomy and hemostatic embolism.
