BACKGROUND Arterial bleeding typically involves the renal artery following partial nephrectomy;in this study,we present a case of bleeding originating from the testicular artery that has not been reported in previous studies.CASE SUMMARY A 52-year-old man suffered hemorrhage from a perinephric branch of the aberrant left testicular artery after an open nephron-sparing surgery for renal cell carcinoma.Clinical signs of bleeding were manifested by the patient,such as fresh blood drainage from the catheter,decreased hemoglobin levels,and significant vital sign changes.Since computed tomography did not show evidence of active bleeding,transcatheter angiography was conducted to identify the bleeding site.Fluoroscopic spot images confirmed bleeding derived from a perinephric branch of the testicular artery originating from the segmental artery of the left renal artery.Using n-butyl-2-cyanoacrylate,successful transcatheter arterial embolization of the affected branch was performed.Immediately after the embolization procedure,the bleeding ceased,and the patient experienced complete recovery devoid of complications.CONCLUSION In patients with postoperative arterial hemorrhage after partial nephrectomy,the testicular artery can be a rare but notable source of bleeding.Accurate bleeding site localization via angiographic evaluation,followed by transcatheter arterial embolization,can be instrumental for safe,prompt,and effective hemostasis.
