An observational clinical study to compare the influence of patient characteristics and type of anaesthesia on neurological outcomes after carotid endarterctomy

This is an observational study that will be conducted in patients who underwent carotid revascularization through carotid endarterectomy. The primary objective is  to determine the in hospital neurological complications in the form of transient ischemic attacks, major and minor strokes, cranial nerve injuries after carotid endarterectomy and its associated risk predictors in patients operated under general and regional anaesthesia. The secondary outcomes are to determine the incidence of cardiovascular complications like myocardial infarction, hemodynamically significant arrythmias and other complication like neck hematoma, need for reoperation, prolonged hospital stay and  to determine the total clamp time, procedure time. Patients information will be collected for demographic and clinical presentation, cardiovascular risk factors and comorbidities.  Type of anaesthesia will be decided by treating anaesthesiologist. The postoperative events that will be studied are transient ischemic attacks, major and minor strokes, cranial nerve palsies.
