ObjectiveTo evaluate the clinical value of super-selected arterial embolization in the treatment of massive acute arterial hemorrhage. Methods33 patients with acute arterial hemorrhage were treated with conservative treatment,but failed to control the bleeding; Selective arterial angiography (DSA) was performed on the bleeding site; and after the bleeding artery defined, super-selected catheterization and embolization were performed, using gelatin sponge. ResultsDSA in all cases showed positive signs of bleeding,represented by contrast extravasation, vascular thickening,distortion,etc. After embolization, 31 patients stopped bleeding immediately;One case with cervical cancer patients bleed again after 10 hours, a second embolization was given and the result was satisfactory.One patient with hemoptysis were not completely stopped bleeding, and the bleeding stopped after active internal medicine. All patients had no serious complications. ConclusionDSA is valuable for the diagnosis of massive acute arterial hemorrhage.Super-selected arterial embolization can not only quickly and effectively stop bleeding and fewer complications；it can be used as the primary method of treatment of acute arterial hemorrhage.
