A planned approach to coexistent cerebrovascular disease in coronary artery bypass candidates
Insights
Patients needing coronary artery bypass surgery with carotid artery disease can undergo combined surgical treatment safely. However, bilateral carotid artery disease increases surgical risks for these patients.
Area of Science:
- Cardiovascular Surgery
- Neurology
- Vascular Surgery
Background:
- Coronary artery bypass grafting (CABG) candidates often have coexisting cerebrovascular disease.
- Extracranial carotid artery lesions can increase the risk of stroke during cardiac surgery.
- Screening for cerebrovascular disease is crucial in patients undergoing CABG.
Purpose of the Study:
- To evaluate the safety and outcomes of combined surgical management for coronary and carotid artery lesions.
- To determine the risks associated with simultaneous versus staged surgical procedures.
- To identify risk factors influencing outcomes in patients with combined pathologies.
Main Methods:
- Screening of 874 consecutive CABG candidates for cerebrovascular disease.
- Identification of 49 patients (5.6%) with significant extracranial carotid lesions.
- Application of a planned surgical approach based on clinical and angiographic criteria.
- Cerebrovascular reconstruction prior to cardiopulmonary bypass (staged for good-risk, simultaneous for poor-risk).
Main Results:
- Combined surgical treatment for unilateral carotid obstruction and coronary disease showed no increased risk compared to CABG alone.
- Patients with bilateral carotid artery disease faced higher operative morbidity and mortality.
- The planned approach allowed for effective management of combined lesions.
Conclusions:
- Combined surgical management is a safe and effective option for CABG candidates with unilateral carotid artery disease.
- Bilateral carotid artery disease in CABG candidates signifies a more complex clinical state with elevated surgical risks.
- Careful patient selection and surgical planning are essential for managing combined coronary and carotid artery disease.
Abstract:
Of a series of 874 consecutive candidates for coronary artery bypass screened for cerebrovascular disease, 49 (5.6%) were found to have significant extracarnial lesions. Combined surgical management of both carotid and coronary artery lesions was then undertaken, using a planned approach based on clinical and angiographic criteria. Cerebrovascular reconstruction was undertaken prior to establishment of cardiopulmonary bypass, utilizing staged procedures in good-risk and simultaneous reconstruction in poor-risk candidates. Our experience indicates that combined surgical treatment of the patient with unilateral carotid obstruction and coronary disease is attended by no greater risk than that attached to coronary revascularization alone. The coronary bypass candidate with bilateral carotid artery disease represents a more advanced clinicopathological state whose treatment is attended by greater risk of operative morbidity and mortality.
