MERTENS M, Renato et al. Carotid endarterectomy under regional anesthesia: Initial experience. Rev. méd. Chile [online]. 2000, vol.128, n.1, pp.53-58. ISSN 0034-9887.

Background: Endarterectomy is the treatment of choice for internal carotid artery critical stenosis. Some authors have proposed that the use of regional anesthesia has advantages over general anesthesia. Aim: To report our initial experience with carotid endarterectomy under regional anesthesia. Patients and methods: Between 1998 and 1999, patients with critical carotid artery stenosis, asymptomatic or with transient and recovered symptoms, were selected. A C2, C3, C4 root deep cervical block and superficial block was performed, using a mixture of lidocaine and bupivacaine. A carotid endarterectomy with patch and without routine shunt insertion, with standard and neurological monitoring, was performed. Results: During the study period, 94 carotid endarterectomies were done, 22 under regional anesthesia in 21 patients (12 male, age range 58-90 years old). Ninety five percent had hypertension, 52% smoked and 38% had renal dysfunction. One patient was converted to general anesthesia. Seventeen patients were discharged within 48 hours of the procedure and the rest, within 72 hours. There was no mortality or complications. Conclusions: Endarterectomy under regional anesthesia is less invasive, has excellent results and is well accepted by patients. (Rev Méd Chile 2000; 128: 53-58)
