Superselective transcatheter arterial embolization to control renal hemorrhage after partial nephrectomy for renal tumors: A report of 9 cases and a literature review

Objective: This study aimed to evaluate the efficacy and safety of selective arterial embolization for hemorrhage after renal surgery and to summarize the clinical experience. Materials and methods: A total of 9 patients underwent arterial embolization after partial nephrectomy from 2010 to 2018. Results: Technical success was achieved in all patients; however, 3 patients underwent a secondary arterial embolization because of short-term re-hemorrhage or the co-occurrence of accessory renal arterial hemorrhage. No serious complications occurred during the follow-up. Conclusions: Superselective arterial embolization is an effective and minimally invasive treatment for hemorrhage after partial nephrectomy. To improve the success rate of surgery, attention should be paid to the evaluation of accessory renal arteries and the management of suspected bleeding arteries. Keywords: Renal tumor, Postoperative hemorrhage, Selective arterial embolization
