Summary
Cerebrovascular accidents (CVAs) occurred in 1.8% of cardiac surgery patients. Severe aortic atherosclerosis and longer cardiopulmonary bypass times were key predictors of post-operative stroke, highlighting the need for risk factor identification.
Area of Science:
- Cardiovascular Surgery
- Neurology
- Vascular Surgery
Background:
- Cerebrovascular accidents (CVAs) are a significant complication following cardiac surgery.
- Identifying predictors of CVA is crucial for improving patient outcomes.
Purpose of the Study:
- To retrospectively review patients undergoing cardiac surgery to identify risk factors for intraoperative or postoperative cerebrovascular accidents (CVAs).
- To determine the incidence and predictors of CVA in patients with acquired heart disease.
Main Methods:
- Retrospective review of demographic data, atherosclerosis risk factors, medical history, and intraoperative findings in 2,455 cardiac surgery patients.
- Analysis of CVA rates in relation to specific surgical procedures and intraoperative findings, including aortic arch atherosclerosis.
Main Results:
- The overall CVA rate was 1.8% (44 of 2,455 patients).
- Highest CVA rate (18.2%) was observed in patients undergoing simultaneous myocardial revascularization and carotid endarterectomy.
- Severe aortic arch atherosclerosis at the cannulation site (43.2%) and longer cardiopulmonary bypass (CPB) and aortic cross-clamping times were significantly associated with CVA.
- Hypertension was an independent risk factor for postoperative CVA.
Conclusions:
- Severe aortic arch atherosclerosis and prolonged CPB times are significant predictors of post-cardiopulmonary bypass CVA.
- Identifying high-risk patients preoperatively is essential for reducing CVA-related morbidity and mortality.
- Simultaneous myocardial revascularization and carotid endarterectomy represent a high-risk subgroup for neurological events.
