The role of digital subtraction angiography in the diagnosis and treatment of small intestinal tumor with massive lower gastrointestinal hemorrhage

Objective To discuss the diagnostic value of DSA for massive hemorrhage in lower gastrointestinal tract resulting from tumour. Methods 24 patients with massive lower gastrointestinal hemorrhage were performed DSA and then operated as tumour. Results Among 24 patients, 17 cases demonstrated direct signs of hemorrhage, 9 cases visible turnout vessels; 24 patients all showed clumping tumour-specifie dyeing.
