Insights
Managing simultaneous carotid artery stenosis and coronary artery disease requires personalized strategies. This review explores surgical, staged, and hybrid approaches to reduce stroke risk during cardiac surgery.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Interventional Cardiology
Background:
- Simultaneous carotid artery stenosis (CS) and coronary artery disease (CAD) frequently coexist in patients with cardiovascular risk factors.
- Optimal management strategies for concurrent CS and CAD remain under investigation.
- The causal link between carotid disease and perioperative stroke, and the benefit of preventive carotid revascularization, are areas of ongoing study.
Purpose of the Study:
- To review and summarize current approaches for managing carotid artery disease in patients undergoing coronary artery bypass graft (CABG) surgery.
- To discuss the state-of-the-art in surgical, staged, and hybrid interventions for CS in patients with CAD.
- To highlight the importance of personalized treatment strategies for these complex patients.
Main Methods:
- Review of current literature and clinical practices regarding the management of combined CS and CAD.
- Analysis of synchronous (CEA before CABG), staged (CEA/CABG or CABG/CEA), and hybrid (CAS with CABG) approaches.
- Evaluation of strategies for reducing perioperative stroke risk in patients undergoing CABG.
Main Results:
- Synchronous carotid endarterectomy (CEA) and CABG can be considered in select patients to mitigate perioperative stroke risk.
- Staged procedures (CEA followed by CABG, or vice versa) and hybrid approaches (carotid artery stenting (CAS) with CABG) offer alternative management options.
- A tailored, individualized approach is crucial, particularly for asymptomatic patients, to determine the optimal surgical strategy.
Conclusions:
- The management of patients with both CS and CAD requires a personalized approach, considering various surgical and interventional options.
- The choice between synchronous, staged, or hybrid procedures should be based on individual patient factors and risk assessment.
- Further research is needed to refine optimal management protocols for this high-risk patient population.
Abstract:
Simultaneous carotid artery stenosis (CS) and coronary artery disease (CAD) is a common condition among patients with several cardiovascular risk factors; however, its optimal management still remains under investigation, such as the assumption that carotid disease is causally related to perioperative stroke and that preventive carotid revascularization decrease the risk of this complication. Synchronous surgical approach to both conditions, performing carotid endarterectomy (CEA) before coronary artery bypass graft (CABG) during the same procedure, should still be considered in selective patients, in order to reduce the risk of perioperative stroke during coronary cardiac surgery. For the same purpose, staged approaches, such as CEA followed by CABG or CABG followed by CEA during the same hospitalization or a few weeks later have been described. Hybrid approach with carotid artery stenting (CAS) and CABG can also be an option in selected cases, offering a minimally invasive procedure to treat CS among patients whom CABG cannot be postponed. When carotid intervention is indicated in patients with concomitant CAD requiring CABG, a personalized and tailored approach is mandatory, especially in asymptomatic patients, in order to define the ideal surgical strategy. The aim of this paper is to summarize the current "state of the art" of the different approaches to carotid artery diseases in patients undergoing CABG.
