Complications after carotid endarterectomy are related to surgical errors in less than one-fifth of cases. Swedvasc--The Swedish Vascular Registry and The Quality Committee for Carotid Artery Surgery.

Abstract

to study possible relations between indications, contraindications and surgical technique and stroke and/or death within 30 days of carotid endarterectomy (CEA). analysis of hospital records for patients identified in a national vascular registry. during 1995-1996, 1518 patients were reported to the Swedish Vascular Registry - Swedvasc. Among these the sixty-five with a stroke and/or death within 30 days were selected for study. Complete surgical records were reviewed by three approved reviewers using predetermined criteria for indications and possible errors. an error of surgical technique or postoperative management was found in eleven patients (17%). In six cases (9%) the indication was inappropriate or there was an obvious contraindication. The indication was questionable in fourteen (21.5%). Half of the patients (52.5%) had surgery for an appropriate indication, and no contraindication or error in surgical technique or management was identified. more than half the complications of CEA represent the "method cost", i.e. the indication, risk and surgical technique were correct. However, the stroke and/or death rate might be reduced if all operations conformed to agreed criteria.
