Abstract:

Objective  To explore the clinical significance of endovascular embolization for acute abdominal bleeding. Methods  A total of 66 patients with acute abdominal bleeding received arteriography and endovascular embolization, among whom 28 had gastric bleeding, 12 intestinal bleeding, 17 uterine bleeding, 3 hepatic bleeding, 2 renal bleeding and 4 postoperative acute bleeding. Results  With selective arteriography, 65 cases were confirmed. The rate of positive diagnosis was 98.5%. The direct sign of bleeding, extravasation of contrast media, was shown in 36 cases, with a positive rate of 54.5%. Pseudoaneurysm was indicated in 13 cases. The tumor blood feeding branches and tumor staining were seen in 21 cases. The thickened uterine arteries and increased number of branches were revealed in 12 cases. The vascular dysplasia was demonstrated in 1 case. The instant hemostasis was achieved in all diagnosed cases by the first embolization without complication. However, one patient with gastrointestinal bleeding relapsed 4 days after embolization and was successfully treated by the second embolization. The success rate of hemostasis was 98.5%. Conclusion  Selective angiography and intravascular embolization can accurately locate the acute bleeding site and achieve rapid hemostasis, which is a safe, quick and cost-effective method.
