Records of 123 consecutive patients who underwent abdominal angiography for blunt trauma were reviewed. Twenty-four patients underwent abdominal angiography on the basis of positive physical findings. Seven (29%) required intervention as determined by angiography and the diagnosis was confirmed. Ninety-nine patients had abdominal angiography in association with angiographic evaluation of the chest, pelvis, head or extremities. In 14 (14%) the angiogram indicated the need for intervention. In 13 this diagnosis was confirmed at laparotomy. The 14th patient was embolized angiographically and did well. Fifty-four patients had peritoneal lavage in addition to their angiograms; 16 were positive and 38 were negative. In 4 patients the lavage was negative and the angiographic findings indicated need for intervention. Of these 4, 3 were confirmed at laparotomy and the 4th patient was embolized angiographically. Indications for abdominal angiography in blunt trauma are the following: incidental to needed thoracic aortography, incidental to angiography when done for pelvic fractures and suspected intra-abdominal injuries when clinical and lavage data are not definitive.
