目的:探讨经保守治疗后无效的急性肾出血的数字减影血管造影诊断及经导管栓塞治疗的临床价值。方法:对20例急性肾出血病例采用经皮股动脉穿刺插管行数字减影血管造影和栓塞治疗,栓塞材料选用自制明胶海绵颗粒和/或弹簧圈等。结果:肾动脉造影明确了出血的部位、程度及相关血管的情况,20例急性肾出血患者栓塞后出血完全停止或逐渐减少停止,并保留了患肾的部分功能。结论:选择性肾动脉数字减影造影与超选择栓塞是急性肾出血可靠的诊断方法和止血手段,并在最大程度上保护了患肾功能。
Objective: To investigate the clinical value of digital subtraction angiography and catheter embolization in the treatment of acute renal failure after conservative treatment. Methods: Twenty cases of acute renal hemorrhage were treated by transvaginal femoral artery puncture cannulation with digital subtraction angiography and embolization. Embolization was made with self-made gelatin sponge particles and / or coil. Results: Renal angiography identified the location and degree of bleeding and related vascular conditions. Twenty patients with acute renal hemorrhage completely stopped or gradually stopped bleeding after embolization, and retained some of the functions of the kidney. CONCLUSION: Digital subtraction angiography and superselective embolization of selective renal artery are reliable methods of diagnosis and hemostasis in acute renal hemorrhage and protect renal function to the greatest extent.
