Abstract
Abstract
Carotid artery stenosis is usually a consequence of thromboembolism or atheroembolism, or it can be secondary to a low-velocity status in the carotid circulation. This disease can also represent an important cause of stroke, being responsible for 7% of all stroke cases. Endovascular techniques were recently proposed as alternative interventions for patients with high risk for endarterectomy. We present the case of a 70-year-old patient, accusing headache, vertigo, and fatigue. Angiography indicated bilateral carotid artery stenosis. Interventional surgery and angioplasty were performed, crossing the stenotic lesions of the left internal carotid artery, followed by the implantation of a Carotid WALLSTENT endoprosthesis. Evolution of the patient was favorable after the endovascular intervention, with significant improvement of the symptoms caused by bilateral carotid stenosis. As a conclusion, decision-making must be modulated in each patient, according to the patient’s anatomy and comorbidities, and the experience of the team performing the procedure.

Abstract
The present study was conducted to determine the correlation between high perfusion syndrome and stent restenosis after cerebral vascular stent implantation. A total of 146 patients diagnosed with cerebral vascular stenosis and stent implantation were selected. A total of 55 cases (37.67%) of cerebral hyperperfusion syndrome patients were diagnosed by xenon-enhanced computer tomography (Xe-CT) examination and clinical symptoms within 3 days after surgery and were chosen as the observation group. A total of 91 cases were selected as the control group. After treatment, blood flow of the anterior cerebral artery, middle cerebral artery, posterior cerebral artery, anterior border zone, posterior border zone and the inner border zone of the two groups increased, with values in the observation group increasing more significantly, and the differences were statistically significant (P<0.05). The rate of restenosis and target lesion diameter one month and one year after operation in the observation group were significantly higher than those in the control group (P<0.05). Multivariate logistic regression analysis showed that the mean systolic blood pressure (mSBP), mean diastolic blood pressure (mDBP), stenosis rate of cerebral vascular diameter and high perfusion syndrome were independent risk factors for restenosis (P<0.05). The application of Xe-CT examination is important for early diagnosis of hyperperfusion syndrome. Hyperperfusion syndrome and the occurrence of stent restenosis are closely related. mSBP, mDBP, cerebral blood vessel diameter stenosis rate and high perfusion comprehensive syndrome are the independent risk factors of restenosis.
