Cranial nerve injury is a well-recognized complication of carotid endarterectomy. Patients are usually not disturbed by these changes. The vagus nerve appears to be the CN most injured during CEA, with a 3.99% incidence of injury and a 0.57% rate of permanent injury; the hypoglossal nerve is the next most injured CN. Rapid access carotid endarterectomy can be performed in the hyperacute period without a significant increase in procedural risks. Bleeding, infection, and cranial nerve injury are also risks at the time of surgery. Stroke 24:1098-9. 2017 Mar;8(1):54-63. doi: 10.1177/2151458516681144. Loss of cervical nerve sensation is always present after carotid endarterectomy but tends to improve with time. However, routine postoperative laryngoscopy undoubtedly established the diagnosis of recurrent laryngeal nerve dysfunction in several patients whose hoarseness might otherwise have been attributed to recent endotracheal intubation during general anesthesia, and it is assumed that vocal cord paralysis occurs more frequently following endarterectomy than often reported. (1995). Zentralbl Chir. Repeated blockage of the carotid artery. 1 Most deficits are transitory but some, such as glossopharyngeal or hypoglossal deficits, can be severely debilitating. The stroke and operative mortality rates associated with carotid endarterectomy have been thoroughly documented. 2011 Feb. 41(2):222-8. The most feared complication of carotid endarterectomy is stroke. Sandmann W. et al (1993). The carotid arteries are blood vessels located on each side of your neck (carotid arteries).This buildup of plaque (atherosclerosis) may restrict blood flow to your brain. The remaining patient (2%) developed vocal cord paralysis which is permanent to date. In addition six patients (12%) developed post-operative hoarseness of whom five have fully recovered. Nevertheless, the risk of cranial nerve injury should be communicated to patients before they undergo surgery. 2016 Jan;26(1):1-133. doi: 10.1089/thy.2015.0020. HHS Complications during and after carotid endarterectomy surgery are dependent on various factors, such as surgeon skill and technique, patient’s risk factors, management before or after surgery. A carotid endarterectomy removes plaque from arteries and lowers the chance that you will have a stroke. Most importantly, in any study reporting on cranial nerve injury related to carotid endarterectomy the rate of permanent lesions seems very low. For all these risks, flow through the shunt may be inadequate to meet cerebral oxygen requirements. Real-world data on SeQuent Please OTW DCB presented at LINC 2021, New standardised reporting system suggests arteriovenous graft infections may be less frequent than previously described, Endovascular aneurysm repair linked to higher readmission rates, CX 2020 LIVE: Strong support for relining peripheral arteries and rivaroxaban use for widespread atherosclerosis, Third-generation Anaconda endograft indicates “satisfactory” aneurysm exclusion at five years. Post-operative laryngoscopy revealed asymptomatic impaired vocal cord mobility in three patients (6%) all of whom recovered completely. Peripheral facial nerve injury related to surgical retraction and/or tissue edema has been reported in 1%-4% of carotid endarterectomies [2-4]. Or new blockage that develops in the artery on the other side of your neck. Verta MJ, Applebaum EL, McClusky DA, Yao JST, Bergan JJ: Cranial nerve injury during carotid endarterectomy Ann Surg 185: 192-195, 1977 8. This study describes our experience in the management of this complication in cases where conservative treatment failed. At the cranial position, a retractor should be placed only when the course of the hypoglossal has been verified or when the retractor is placed superficially. The hypoglossal nerve appears to be most susceptible to injury because of its proximity to the carotid bifurcation, followed by vagal nerve injury. Clipboard, Search History, and several other advanced features are temporarily unavailable. Franch-Arcas G, González-Sánchez C, Aguilera-Molina YY, Rozo-Coronel O, Estévez-Alonso JS, Muñoz-Herrera Á. Gland Surg. USA.gov. This complication... Heart Attack. This has been confirmed by randomised controlled trial data and data from large prospective registries. This disease occurs when fatty, waxy deposits build up in one of the carotid arteries. The ECST trial reported motor cranial nerve injury in 5.1% of patients, but the initial clinical assessment was made by the operating surgeon, and the patient was only examined by a neurologist a few months later. Stroke (embolic) and death; Bleeding + haematoma; Cranial nerve damage (facial nerve, hypoglossal nerve, vagal nerve, superior laryngeal nerve, glossopharyngeal nerve) Complications of carotid endarterectomy include: Major complications. Gowd A, Nazemi A, Carmouche J, Albert T, Behrend C. Geriatr Orthop Surg Rehabil. Eur J Vasc Endovasc Surg . However, the timing and extent of this improvement is unpredictable. 2011 Feb. 41(2):222-8. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Recurrent laryngeal nerve dysfunction is a significant complication of carotid endarterectomy and vocal cord paralysis is a major source of morbidity. Cranial and cervical nerve injuries after carotid endarterectomy: a prospective study. BIBA Medical, North America NIH Is there a case for selective, rather than routine, preoperative laryngoscopy in thyroid surgery? As a general rule, no nerves crossing the bifurcation should be divided. 15.2 What are potential complications of carotid endarterectomy. This prospective study demonstrates that recurrent laryngeal nerve dysfunction is a common but often transient complication of carotid endarterectomy. To reduce the risk of... Nerve Damage. Cranial nerve injuries during carotid endarterectomy are well described and occur in 4.6% to 15.1% of cases. ... Nerve damage, affecting your voice box, tongue or back ↑ Description. NLM There is an associated risk of local complications including haematoma, nerve injury, infection, and late carotid restenosis. Editor: Jocelyn Hudson jocelyn@bibamedical.com Prevention and treatment information (HHS). Gert Jan de Borst is a vascular surgeon in the Department of Vascular surgery, UMC Utrecht, Utrecht, The Netherlands, Write to us Hogue, C.V. et al. 2004 Feb;37(1):25-44, v. doi: 10.1016/S0030-6665(03)00172-5. 2015 Feb;4(1):8-18. doi: 10.3978/j.issn.2227-684X.2015.01.04. Although ECST data may contain an underestimation of the immediate postoperative risk, they do provide reliable data on the risk of persistent symptomatic deficits. Dissection posterior to the common carotid artery should adhere closely to its adventitial layer without excessive manipulation of the carotid sheath containing the vagus nerve, and the proximal vascular clamp should be applied to the common carotid artery only at a point at which the artery is completely isolated from the nerve and surrounding tissue. The Vascular Study Group of New England recently determined the cranial nerve injury rate at discharge and at median 12 months in all patients undergoing carotid endarterectomy between 2003 and 2011. The stroke and operative mortality rates associated with carotid endarterectomy have been thoroughly documented. Otolaryngol Clin North Am. This case demonstrates an unusual complication of local anesthesia for carotid endarterectomy--a peripheral facial nerve palsy. 2013 Dec;5(12):699-702. doi: 10.4103/1947-2714.123254. Background: Inadvertent injury to the vagus nerve or its branches during carotid endarterectomy can result in adductor vocal cord paralysis (hoarseness) and cricopharyngeal dysfunction (dysphagia) with aspiration, known as "double trouble." Observation of vocal fold and pharyngeal paralysis after carotid endarterectomy using a magnifying laryngoscope. Steurer M, Passler C, Denk DM, Schneider B, Niederle B, Bigenzahn W. Laryngoscope. This nerve is responsible for the function of the middle pharyngeal constrictor muscle, which regulates the swallowing mechanism. 1 Risks from undertaking CEA include stroke, cranial nerve palsy (or permanent nerve damage), a moderate risk of MI and some risk of infection and bleeding. If you are allergic to or sensitive to medicines, contrast dye, iodine, or latex, tell your healthcare provider. Postoperative complications include stroke and MI, but also may include neck hematoma and airway compromise. Haugen BR, Alexander EK, Bible KC, Doherty GM, Mandel SJ, Nikiforov YE, Pacini F, Randolph GW, Sawka AM, Schlumberger M, Schuff KG, Sherman SI, Sosa JA, Steward DL, Tuttle RM, Wartofsky L. Thyroid. The more you know about your carotid endarterectomy recovery, the more likely it is that you can return to your normal life withi… Carotid endarterectomy complications. Again, the vast majority of cranial nerve injuries were transient, and only 47 patients (0.7%) had a persistent cranial nerve injury.
