Abstract.Carotid artery stenosis is a significant risk factor for stroke. In elderly patients with carotid atherosclerosis and stenosis, it is not unusual for oral, head and neck cancer surgery to be performed. The present study describes a case of stroke that occurred during a neck dissection for the treatment of cervical lymph node metastasis of a left maxillary gingival carcinoma. The patient was an 84-year-old female who was considered to be at high risk of a stroke based on pre-operative head and neck computed tomography scans, which detected severe carotid atherosclerosis and stenosis. There was no possible stroke prophylaxis available during the performance of the neck dissection in the present case. However, if patients are evaluated to be high-risk pre-operatively, statin agents should be administered, the surgery should be carefully performed, adequate sedation should be maintained post-operatively and the patient should be followed up, aiming to achieve the early detection of a possible stroke.

“…Ulcerated lesions are associated with intraplaque hemorrhage; 50% to 70% of patients with this type of plaque have hemispheric symptoms. 20 Characteristics of the plaque are independent parameters, unrelated to plaque size and stenosis diameter percentage, which should be taken into account for therapeutic planning when the patient is symptomatic and the diameter of the stenosis does not reach the threshold of 70%. 19,20 It should be noted that Table 1 is an overall classification of plaques but not one that is routinely applied clinically or systematically included in the examination report of carotid duplex sonographic examination.…”

A plaque estimate of diameter percentage reduction is considered a primary parameter, together with ICA peak systolic velocity (PSV) for the diagnosis of the degree of ICA stenosis (Table 2).…”

Objective. The goal of this review article is to present the state of the art in the clinical applications and technical performance and interpretation of carotid sonographic examinations. Methods. Relevant publications regarding color and duplex Doppler sonography (CDDS) of the carotid arteries extracted from a computerized database (MEDLINE) and from references cited in these articles not appearing on the Internet were reviewed. Results. The ability to quickly and efficiently identify stenosis in the carotid artery is an important goal for clinicians and vascular surgeons. Identification of potentially treatable carotid stenosis enables selection of appropriate candidates for endarterectomy or stent implantation. Advances in performance and interpretation of carotid sonographic studies over the last 20 years have been driven by technological improvements in gray scale and CDDS examinations and have made carotid sonography an important means to reach this goal. On the basis of CDDS, intimamedia thickness measurements and plaque location and characterization on gray scale imaging, flow disturbance and areas of stenosis on color Doppler sonography, and flow velocities on spectral Doppler sonography are obtained. The degree of the diameter of a stenosis of the internal carotid artery is the main parameter used for therapeutic approaches. Advantages and limitations of the method are included. Conclusions. Carotid sonography is a unique imaging method for the investigation of carotid abnormalities. Noninvasive, accurate, and cost-effective, it provides morphologic and functional information. It is increasingly becoming the first and often the sole imaging study before endarterectomy, whereas costly and invasive procedures are reserved for special cases.
