IntroductionCarotid endarterectomy is performed for patients with symptomatic carotid artery occlusions. Surgery can be performed under general and regional anesthesia. Traditionally, surgery is performed under deep cervical plexus block which is technically difficult to perform and can cause serious complications. This case series describes 5 cases in which an intermediate cervical plexus block was used in combination with a superficial cervical plexus block for Carotid endarterectomy surgery.MethodsFive patients who were classified as American Society of Anesthesiologists 2-3 were scheduled for Carotid endarterectomy due to symptoms and more than 70% occlusion of the carotid arteries. The procedures were carried out in the University Teaching Hospital- Peradeniya, Sri Lanka. All patients were given superficial cervical plexus block followed by intermediate cervical plexus block using 2% lignocaine and 0.5% plain bupivacaine.ResultsAdequate anesthesia was achieved in 4 patients, and local infiltration was necessary in 1 patient. Two patients developed hoarseness of the voice, which settled 2 h after surgery. Hemodynamic fluctuations were observed in all 5 patients. No serious complications were observed. All 5 patients had uneventful recoveries.DiscussionsRegional anesthesia for CEA is preferable in patients who are medically complicated to undergo anesthesia or in patients for whom cerebral monitoring is not available. Intermediate cervical plexus block is described for thyroid surgeries in literature, but not much details on its use for carotid surgeries. Deep cervical plexus blocks has few serious complications which is not there with the use of ICPB making it a good alternative for CEA surgeries .ConclusionsSuperficial cervical plexus block and intermediate cervical plexus block can be used effectively for providing anesthesia for patients undergoing Carotid endarterectomy. It is safe and easier to conduct than deep cervical plexus block and enables monitoring of cerebral function.© 2024. The Author(s).
