Angiographic investigation of patients with transient ischaemic attacks.

Abstract

Arteriographic abnormalities were studied by means of angiography in a series of 66 patients with transient ischemic attacks. When 4 vessels were examined instead of 1, the incidence of abnormalities increased from 14% to 66%. Patients with bruits had more abnormalities than those without. Valuable information can be obtained by means of 4-vessel angiography via the axillary artery in these patients.
