46 CTA were performed for upper GIH (28 positive for active bleeding,
18 negative) and 28 for lower GI hemorrhage (17 positive for active bleeding,
11 negative); 30/46 (65.21%) of the uGIH patients and 21/28 (75.00%) for lGIH were successfully treated in DSA with good clinical recovery; 39.13% (18/46) of patients with upper GI bleed and 39.28% (11/28) of patients with lower GI bleed who had an initial negative CTA,
did not rebleed without the need for radiological or surgical intervention.
This difference was not statistically significant (p = 0.05).
The relative risk of rebleeding,
following a negative CTA,
in lower GI bleeding versus upper GI bleeding patients is 0.55 (95 % confidence interval 0.32-0.95).
