Abstract:
Objective To evaluate the selective angiography and interventional management in nonvariceal gastrointestinal hemorrhage.Methods 94 cases with nonvariceal gastrointestinal hemorrhage were accepted for selective angiography.According the location and cause of hemorrhage finding by angiography,these patients were checked by arterial embolization and/or perfusion of vasoconstrictor substance.Results DSA revealed positive result in 58 cases(61.7%) of 94 cases.Meanwhile,13 cases accepted 99m Tc-labeled erythrocytes nuclear scan,11 cases(84.6%) showed hemorrage.Arterial embolization was carried out in 34 cases,the hemostasis and relapse rate was 91.2% and 8.8% respectively.Besides arterial embolization,8 cases were selected vasopressin infusion,the hemostasis and relapse rate of vasopressin infusion was 75.0% and 25.0% respectively.No severe complication such as intestinal necrosis occurred among the 42 cases with interventional therapy.Conclusion Selective angiography is a valuable method for the diagnosis of the nonvariceal gastrointestinal hemorrhage of unknown reasons.The()~(99m)Tc-labeled erythrocytes nuclear scan is more sensitive than selective angiography in detecting bleeding,however,as to find bleeding location accurately,it was inferior to selective angiography.
