Does angiographic localization of bleeding affect the management and mortality in gastrointestinal hemorrhage of unknown origin?
Angiographic localisation should be attempted in all cases of unknown GI-bleeding after endoscopic methods have been unsuccessful or ambiguous, because such a procedure has a positive effect on patient management and outcome. Moreover, angiography also offers therapeutic options.
Duplex scanning detects cervical vascular injuries as effectively as arteriography or operation, and is faster and less expensive. This approach expands the utility of diagnostic ultrasound in the evaluation of trauma patients. It has become the procedure of choice for diagnosing cervical vascular trauma at our institution.
