Abstract：Objective: To evaluate the clinical value of super-selective arterial embolization in treating acute renal hemorrhage. Methods: All cases underwent angiographic examination and the diagnosis was confirmed. Super-selective embolization was performed in 15 patients with acute renal hemorrhage by renal artery injury(n=5), iatrogenic renal artery injury(n=3), and renal arterioveous malformation(n=7). Average follow-up period was 12 months(range 6～18 months). The therapeutic effect, complication and bleeding recurrence of super-selective embolization in the treatment of acute renal hemorrhage were evaluated. Results: The super-selective arterial embolization was successfully accomplished in all the 15 patients. Immediate hemostasis was achieved in 14 patients after super-selective embolization. One patient had a kidney excision because of a recurrent postoperative hemorrhage. During the clinical follow-up period, no severe complication or recurrent hemorrhage was observed. Conclusion: Super-selective renal artery embolization is a safe and effective treatment with few complications for acute kidney bleeding.
