• Fiberoptic angioscopy was performed with 2.5- and 3.3-mm angioscopes in 25 arteries and grafts in 19 patients. Radiologically normal and abnormal arteries and anastomotic sites were examined. All vessels and grafts were visualized and images of normal arterial wall, subclinical and obstructing atherosclerotic plaque, and suture lines were defined. Unexpected endovascular findings were noted in five patients (26%) and included large amounts of free-floating clot (one patient), atherosclerotic debris (two patients), and membranelike obstructions (two patients). Angioscopy required three to ten minutes and resulted in no complications. Experience with the flexible angioscope indicates that satisfactory visualization and specific recognition of angiographically unsuspected problems can be obtained. The flexible angioscope is faster and appears more etiologically specific than arteriography.
