Coronary artery disease frequently occurs in combination with peripheral vascular disorders and is an important cause of morbidity and mortality during or after peripheral vascular surgery. However, the detection of coronary artery disease in patients with peripheral vascular disease may be complicated, since most of these patients are unable to perform conventional exercise testing. The authors report a sixty-two-year-old man with an infrarenally located aneurysm of the abdominal aorta who underwent thallium 201 scintigraphy combined with dipyridamole infusion as an alternative exercise test. The subsequent thallium 201 images showed perfusion defects indicative of severe coronary artery disease. Coronary angiography showed an occluded right coronary artery and a significant proximal stenosis in the left anterior descending coronary artery. The patient underwent successful aortocoronary bypass surgery, and two months later, the aortic aneurysm was operated on without complications. As a result, dipyridamole thallium 201 scintigraphy should be considered as a valuable diagnostic test to detect coronary artery disease in patients with peripheral vascular disorders.
