Abstract

SUMMARY:
Six cases of Transient cerebral Ischemic attacks (TIAs) within the carotid system territory and 10 cases with TIAs in the Vertebral basilar system territory were followed up, salient clinical features, differential diagnosis, complications and their mechanism have been described.

PATIENTS AND CLINICAL METHODS:

Six out of 120 hypertension cases were followed-up who had TIAs in the carotid territory during the past five years (about 1% per year). The clinical findings were analysed carefully and followed up regularly cases in this study included were fulfilling the criteria of TIA either in the carotid or vertebro-basilor territory.

DISCUSSION:

There are three separate streams of arterial blood supplying the brain: one from the basilar artery and one from each internal carotid artery separated from the another by dead points, in the posterior and anterior communicating arteries at which points the pressure of the two opposing stream is balanced.
