Anesthetic management of carotid endarterectomy.
Objective: It is generally accepted that carotid endarterectomy (CEA) reduces the risk of stroke in symptomatic patients, with less risk reduction for asymptomatic patients. Although the comorbidities of these patients combined with the hemodynamic goals for the procedure pose unique perioperative challenges, patients undergoing CEA attain excellent outcomes. Nonetheless, heightened focus on perioperative management of comorbidities is increasingly important as older and more complex patients present with carotid artery disease. Although controversial, the efficacy, safety, and durability of carotid angioplasty and stenting (CAS) have been better defined in recent years. The 2012 literature presents several developments in the anesthetic management of CEA. Selected publications regarding CAS are also reviewed.
Results: Interest has focused on patient selection, comorbidities, prediction of risk, anesthetic technique, and monitoring methods. Recent studies regarding CAS reflect interest in defining the durability of CAS, and comparative efficacy and cost of CEA versus CAS versus medical therapy.
Conclusions: Patients with significant comorbidities may be managed safely by a variety of anesthetic techniques. Maintaining focus on physiologic management, and monitoring the brain remain important goals of perioperative management. Recent data suggest that the durability and safety of CAS are not inferior to those of CEA.
