[Carotid endarterectomy, clinical analysis of 43 cases]

To evaluate the important points in carotid endarterectomy.

Carotid endarterectomy was performed upon 43 cases of carotid artery stenosis under cervical plexus anaesthesia. The operation was performed with shunting between the common carotid artery and the internal carotid artery in 2 cases.

The average clamping time of carotid artery was 27 min +/- 7 min. There were one case suffering from transient ischemic attack (TIA), 7 cases suffering from hypertension and 2 cases suffering from light edema of the wound. All of the patients recovered uneventfully. Twenty-six patients who had suffered from TIA before operation felt much better after operation. The follow-up of one month to one year showed a better condition among all patients.

Cervial plexus anaesthesia helps diagnose stroke during operation. Shunting between the common carotid artery and internal carotid artery helps avoid ischemic brain injury. The effect of operation depends upon complete removal of the residual tunica intima, complete exsufflation, and control of hypertension postoperationally.
