Combined surgical approach to coexistent carotid and coronary artery disease
1Department of Cardiac Surgery, ospedale Niguarda Ca Granda, Milan, Italy.
Insights
Simultaneous carotid endarterectomy with coronary artery bypass surgery is safe and effective for patients with significant carotid stenosis. This combined procedure offers a practical approach, reducing risks and improving outcomes for eligible individuals.
Area of Science:
- Cardiovascular Surgery
- Neurosurgery
- Vascular Surgery
Background:
- Patients requiring coronary artery bypass grafting (CABG) often have concomitant significant carotid artery stenosis.
- Carotid artery disease increases the risk of perioperative stroke in patients undergoing cardiac surgery.
- The management of combined coronary and carotid disease requires careful consideration of surgical timing and approach.
Purpose of the Study:
- To evaluate the safety and efficacy of performing combined coronary artery bypass surgery and carotid endarterectomy simultaneously.
- To assess the perioperative morbidity and long-term outcomes of this combined surgical strategy.
- To determine the feasibility and benefits of a single-stage surgical intervention for patients with both conditions.
Main Methods:
- A retrospective review of 52 patients who underwent combined coronary artery bypass and carotid endarterectomy between 1981 and 1990.
- Analysis of patient demographics, preoperative risk factors, surgical details, and perioperative outcomes.
- Long-term follow-up to assess survival rates, freedom from major adverse events, and functional status.
Main Results:
- No early deaths were recorded. Perioperative myocardial infarction occurred in 7.7% and neurological deficit in 5.7%, with no permanent functional impairment.
- The 5-year life-table survival rate was 83%, with 67% of patients free from major adverse events or death at five years.
- Late mortality and morbidity were primarily associated with the progression of coronary artery disease.
Conclusions:
- Simultaneous coronary artery bypass surgery and carotid endarterectomy is a safe and viable option for selected patients.
- This combined approach is considered more practical for patients, potentially reducing overall treatment time and hospital stay.
- Careful patient selection and surgical planning are crucial for optimal outcomes in combined coronary and carotid revascularization.
Abstract:
Combined coronary artery bypass and carotid endarterectomy were performed in 52 patients (mean age 61 years) between 1981 and 1990. Of these, 36 (69%) had functional class III-IV angina pectoris, 33 (63%) had triple-vessel disease, 36 (69%) had one, or more, previous myocardial infarctions, and 33 (63%) had an abnormal left ventricular function. In 4 cases, additional cardiac procedures were performed. Asymptomatic carotid stenosis was documented in 29 patients (56%) and the remaining 23 (44%) had experienced cerebrovascular symptoms. All patients had hemodynamically significant stenosis of at least one carotid artery, 17 (33%) had severe bilateral carotid artery stenosis, and 6 (11%) had an additional occlusion of the contralateral internal carotid artery. There were no early deaths. Perioperative morbidity included: myocardial infarction in 4 patients (7.7%) and neurological deficit in 3 (5.7%) but functional impairment was not permanent. Late results have been obtained for all 52 patients at a mean postoperative interval of 35 months. Four patients (7.7%) have died, and the 5 year life-table survival rate was 83%. At five years, actuarial curves showed 67% of patients to be free of all serious events or death. Late mortality and morbidity were related above all to the progression of the coronary artery disease. We concluded that simultaneous endarterectomy of significant carotid artery stenosis in candidates for coronary bypass can be done safely and considered as more practical for the patient.
