title: GI hemorrhage arising from splenic artery: intraprocedure cone-beam CT as problem-solving tool to aide in safe catheterization of offending vessel.
abstract: We present the case of a 67-year-old female with melena and hypotension who was found to have a bleeding splenic artery pseudoaneurysm subjacent to a large gastric ulcer on computed tomographic angiography. The lesion was angiographically occult on standard anteroposterior and oblique projections. The offending vessel was identified on intraprocedure cone-beam computed tomography (CT). This case illustrates the value of intraprocedure cone-beam CT as a problem-solving tool for the interventional radiologist.
