RESUMO

Stroke after coronary bypass grafting (CABG) is often disabling. The incidence of ischemic stroke may approach 3% to 5%. Several risk factors have been identified including previous history of stroke, prolonged cardiopulmonary bypass time, and postoperative atrial fibrillation. Retrospective study during the period 1992-1995 was undertaken to determine the incidence, risk factors of neurological deficit after open-heart surgery at King Khalid University Hospital, Riyadh, Saudi Arabia. There were 350 patients who were subjected to CABG, 10 patients (2.8%) were found to suffer from cerebrovascular accidents (CVA) following open-heart surgery. In 18 patients, the complaint lasted more than 24 hours (stroke), while 2 patients developed transient ischemic attacks (TIA). Five factors were found to be associated with increased risk of post cardiac surgery CVA. These factors are postoperative atrial fibrillation, carotid bruit, past history of heart failure, past history of CVA and smoking. The authors concluded that it is necessary to start a prospective study to verify the area of improvement with regards to technique, selection of patients and mode of perfusion during cardiopulmonary bypass (CPB).
