title: Selective use of arteriography in the assessment of aortic aneurysm repair.
abstract: Routine preoperative arteriography is advocated by many vascular surgeons before abdominal aortic aneurysm repair. We have used a selective approach based on the facts that arteriography is expensive, time-consuming, potentially hazardous, and often unwarranted. Based on preoperative indications, arteriography was used selectively in 41 of 100 consecutive patients prior to abdominal aortic aneurysmectomy. Many patients had more than one indication. A total of 82 specific indications were recognized. The most frequent indications were diminished lower extremity pulses (24), claudication (20), severe coronary artery disease (11), cerebrovascular disease (7), prior arterial reconstruction (8), hypertension in patients 60 years of age or less (5), evidence of other aneurysms (4), major renal anomaly (1), blue toe syndrome (1), and thoracic aneurysm (1). The 41 arteriograms produced 125 specific arteriographic abnormalities with an average of three per study. The most arteriographic abnormalities were in those patients with claudication and the least for those with hypertension. The arteriogram revealed information that would not have been obvious at operation, nor would it have led to operative procedure modification in only 10 patients. In the 59 patients not having arteriography, three had intraoperative findings which demanded a modification of the operative procedure. Thus, in only 13 patients was arteriography definitely useful. Presumably it was not indicated in the other 87. By comparing the cases in which the operation was modified with the presence of a specific indication, we have developed a predictability index as a guide for performing arteriography. Multiple indications increased the likelihood of operation modification only if four or more indications were present.
