Clinical Application of Superselective Renal Artery Embolization in the Treatment of Renal Hemorrhage

超选择性肾动脉栓塞(SRAE)是一种微创技术，在急性肾出血治疗中表现出高效性和安全性。研究显示，SRAE即刻止血成功率达96.7%，并显著减少术后并发症及输血需求。通过数字减影血管造影精确定位出血部位，并使用不同栓塞材料，SRAE能够有效保护肾功能，且复发率较低。该技术为复杂病例提供了可靠的治疗选择，并展现了良好的长期效果。Superselective renal artery embolization (SRAE) is a minimally invasive technique that has demonstrated efficacy and safety in the treatment of acute renal hemorrhage. The study showed that the success rate of immediate hemostasis with SRAE was 96.7%, and the postoperative complications and blood transfusion requirements were significantly reduced. By using digital subtraction angiography to pinpoint the bleeding site and using different embolic materials, SRAE can effectively protect renal function and have a low recurrence rate. The technology provides a reliable treatment option for complex cases and has demonstrated good long-term results.
