A37 EFFICACY OF CTA IN DIAGNOSING NON-TRAUMATIC NON-VARICEAL GASTROINTESTINAL BLEEDING PRIOR TO TRANSARTERIAL EMBOLIZATION AFTER ENDOSCOPIC FAILURE IN MANAGING ACUTE GASTROINTESTINAL BLEEDING

摘要

BackgroundNon-variceal gastrointestinal bleeding (NVGIB) is associated with a high mortality and morbidity. 10–30% of these patients tend to fail endoscopy and receive transarterial embolization (TAE) as an alternative. Studies suggest that performing pre-angiography computed tomography angiography (CTA) increases the positive yield of visceral angiography.
