This article reports that a patient with bilateral ureterocutaneous stoma after radical cystectomy developed intermittent hematuria 2 years after surgery, and there were no abnormalities on bilateral renal artery and abdominal aortic angiography. After removal of the double J stent, a left common iliac artery ureteral fistula was seen on abdominal aortic angiography, and the patient immediately developed hemorrhagic shock. Abdominal aortic balloon occlusion and left common iliac artery stent grafting were performed in the emergency department. After the stent was deployed and the balloon deflated, no bleeding was observed, and the patient's heart rate and blood pressure stabilized. Follow-up angiography showed complete resolution of the fistula. This condition is rare and dangerous, but interventional treatment can quickly control bleeding, offering minimal surgical trauma and fast recovery.

Objective To investigate the clinical efficacy and value of interventional treatment of iatrogenic massive vaginal bleed-ing.Methods Retrospective analysis was performed on 35 patients with postoperative vaginal massive hemorrhage in obstetrics and gynecology who were admitted.Abdominal aorta and bilateral internal iliac arteries angiography and embolization of abnormal vessels were performed under digital subtraction angiography(DS A),and relevant clinical data were recorded and analyzed.Results After interventional treatment,the vaginal bleeding of 33 patients basically stopped within 3 days,and the average interventional operation time was(57.5±17.2)min.The hemoglobin value,hematocrit and blood pressure decreased and the heart rate increased significantly before and after interventional embolization in obstetrics and gynecology,with statistical significance(P＜0.05).There were no sig-nificant changes in hemoglobin value and hematocrit between the completion of interventional embolization and 72 hours after interventional embolization(P＞0.05).The increase of blood pressure and the decrease of heart rate were statistically significant(P＜0.05).Two patients with cesarean section had poor hemostatic effect after interventional embolization,and the bleeding stopped after exploratory laparotomy and hysterectomy.Conclusion Interventional treatment has the advantages of small trauma,simple operation,signifi-cant curative effect,few adverse reactions,and rapid recovery.It plays an important role and clinical value in the diagnosis and treat-ment of iatrogenic vaginal bleeding.
