Poultsides and colleagues conducted a retrospective review over a 10-year period of patients with uncontrolled upper GI tract hemorrhage who were treated with angiography and embolization. This highly selective group of 57 patients had significant comorbidities: one-quarter had multiple organ system failure; similar percentages had immunocompromise, renal failure, or coagulopathy. Remarkably, some patients were referred to angiography by consultants who chose not to obtain a surgical consultation.
