Summary
Combined carotid endarterectomy and cardiac surgery effectively treats simultaneous carotid and cardiac disease in high-risk patients. This approach offers an acceptable method for correcting both conditions during a single procedure.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Neurosurgery
Background:
- Simultaneous surgical correction of carotid artery stenosis and cardiac disease presents unique challenges.
- A combined cardiac operation and carotid endarterectomy technique was developed to address these dual pathologies.
Purpose of the Study:
- To evaluate the safety and efficacy of a combined cardiac operation and carotid endarterectomy technique.
- To assess outcomes in a high-risk patient cohort requiring simultaneous intervention for carotid and coronary artery disease.
Main Methods:
- 121 consecutive patients underwent combined coronary artery bypass grafting and carotid endarterectomy (n=112) or with valve surgery (n=9).
- All patients had critical carotid artery stenosis (≥85%).
- A single aortic cross-clamp period was used with retrograde blood cardioplegia and systemic hypothermia for myocardial and cerebral protection.
Main Results:
- The mean cross-clamp time was 118 minutes.
- Perioperative cerebrovascular accidents occurred in 5.8% of patients, with 1.7% experiencing transient ischemic attacks.
- The overall procedure-related mortality rate was 5.8%.
Conclusions:
- The combined technique is a viable option for simultaneous repair of coronary and carotid lesions in high-risk patients.
- This approach demonstrates acceptable outcomes for managing concomitant cardiovascular and cerebrovascular disease.
