Abstract

English

100 Patients undergoing simultaneous carotid endarterectomy and heart surgery using cardiopulmonary bypass were examined retrospectively. Pre- and postoperative data were collected and analyzed. Risk factors influencing the postoperative outcome were identified. Within a 30 day postoperative period ten patients died, predominantly suffering cardiac causes. No patient died as a consequence of a neurologic complication. Three patients presented a transient ischaemic attack. Seven patients suffered a stroke, one of them recovered from all neurologic symptoms. The data analysis showed that the risk of death increased with the patient’s age above 70 years and also in the case of an occurring low output syndrome. Patients with bilateral carotid artery stenosis had a significantly higher risk to suffer neurologic complications. For this high risk patient population there isn’t yet enough data to identify the best operative procedure. Hence, further clinical trials are needed.
