Abstract
Objective: To explore the value of selective angiography in the diagnosis of arterial hemorrhage of the lower digestive tract and the value of keeping the mark of catheter or guide wire in guiding the surgery, and to decrease the blindness in surgical operation. Methods: The angiographic features in arterial hemorrhage of the lower digestive tract were analyzed in 25 cases, and in 18 cases of which, the mark of catheter or guide wire was placed simultaneously as localizing mark. Result: In 25 cases of arterial hemorrhage of the lower digestive tract, positive angiographic features were displayed in 23 cases, the accuracy rate is 92%; In 18 cases(emergency operation in 13 cases, selective operation in 5 cases) of keeping the mark of catheter or guide wire in place, the bleeding site were all accurately discovered, the rate of localization is 100%. No complications of intestinal ischemia and necrosis resulting from the placement of localizing mark were found during operation in 18 patients. Conclusion: Selective angiography is the best effective method in diagnosis of arterial hemorrhage of the lower digestive tract. Placement of localizing mark of catheter or guide wire can be of help to the surgeon in finding the bleeding site and resecting primary affection of hemorrhage successfully without complication. It is a better localizing method and should be widely used.
