Abstract

In the article we analyzed the results of 123 monthes observation of 126 pts with moderate stenoses of carotid arteries (from 30 to 60% - NASCET).

In 101 patients there was probability of stroke because of presence of ‘potentially embolic plaques’. This conclusion was based on the results of duplex angioscanning. Cerebral embolic episodes were revealed in 41 pts (40,6% from all instable plaques) by Transcranial Doppler (TCD) monitoring.

We developed new classification of cerebral embolic episodes by the results of 1-our TCD monitoring.

We made a conclusion that there are two reliable criteria for making diagnosis of damaging intimal surface of carotid plaques: 1) instable plaques revealed by TCD; 2) ‘potentially embolic plaques’ revealed with duplex angioscanning.

Patients with unstable carotid plaques have to be operated in cases of arterio-arterial embolic episodes in despite of the presence on moderate carotid stenoses.
