Multiple-plane angiography for more precise evaluation of aortoiliac disease.

Abstract

In 14 patients an oblique view of the aotoiliac region was obtained in addition to the conventional anteroposterior view. Angiograms in oblique projections are indicated in the following situations: (1) where the symptoms cannot be explained by the findings on the conventional anteroposterior view (2) where the patient has had previous anoroiliac grafts and has redeveloped ischmic symptoms, and (3) where patients with unilateral limb ischemia due to unilateral aotoiliac occlusive disease are being considered for a femororfemoral bypass graft procedure. In six patients appreciation of the true significance of the suspected occlusive lesion was of great value in planning the proper surgical procedure. In the remaining eight, angiographic corroboraion of the absence of significant occlusive disease was equally helpful in managing the patient's condition. Examples of each group are presented.
