Intracranial arterial dolichoectasia (IADE) is observed in 12% of patients with brain infarction. The artery most often affected is the basilar artery (BADE).1 Coronary artery ectasia (CAE) is the sacular or fusiform dilatation of coronary and is observed in 5% of coronary angiographies.2 CAE is associated with angina pectoris and myocardial infarction independently of coronary atherosclerosis.3 Both IADE and CAE have been reported in association with abdominal aortic aneurysm (AAA) in case series4 and case-control studies,5,6 suggesting that the process causing these arterial dilatations also affects other arterial beds. We previously found that IADE in stroke patients was strongly associated with a clinical history of myocardial infarction.1 There is no report of an association between IADE and CAE.
We report on four patients with BADE and CAE, one with AAA, suggesting that these abnormalities are part of a systemic vascular ectatic disease.
Case reports.
Patient 1.
A 73-year-old hypertensive, obese, diabetic man had unstable angina pectoris in 1985 with three vessels lesions treated by coronary artery bypass graft. In 1999, a follow-up coronary angiography showed no stenosis on the …
