Aims: Objectives: After carotid endarterectomy in patients with carotid stenosis, the authors wish to investigate whether preoperative arterial spin labeling MRI can predict cerebral hyperperfusion. Methods were included in the article "Conservative patients with carotid stenosis who underwent CEA between May 2015 and July 2021. " A cerebral blood flow ratio map was created for each patient by dividing postoperative CBF with preoperative CBF images from two pseudo-continuous ASL scans. The presence of arterial transit artifacts in ten areas of concern related to the Alberta Stroke Programme Early Computed Tomography Score methodology was determined by analysts based on the presence of arterial transit artifacts in ten regions of concern in ten regions of concern corresponding to the Alberta Stroke Programme Early Computed Tomography Score methodology. In 17 patients, cerebral hyperperfusion was present in 86 patients; cerebral hyperperfusion was observed in 17. Conclusions ASL can non-invasively forecast cerebral hyperperfusion in patients with carotid stenosis after CEA in patients with carotid stenosis. u2022 For patients with carotid stenosis, preoperative ASLs can non-invasively identify patients at risk of cerebral hyperperfusion after carotid endarterectomy without complicated post-processing steps.

paraphrased stenosis, which is a natural occurrence. Carotid endarterectomy is common following an ischemic stroke. During carotid endarterectomy, the case of an 85-year old male with perioperative haemodynamic stroke is presented. Ischemic stroke was triggered by abruptly elevated carotid stenosis, resulting in a significant neurological deficit. Conclusion We strongly recommend the use of multimodal neuromonitoring, including transcranial doppler whenever possible to reduce the risk of persistent neurologic deficit following carotid endarterectomy.

DSA is the gold standard for testing carotid artery stenosis. BACKGROUND and purpose DSA is the center of carotid artery stenosis. However, the association between DSA and stenosis is not well documented. CS as measured by DSA to carotid artery specimens obtained from carotid endarterectomy surgery was compared by DSA to carotid endarterectomy surgery. Patients were divided into three groups based on NASCET criteria: stenosis of 30 percent, stenosis of 50 percent, and stenosis of 70 percent were divided into three groups. The mean stenosis in the moderately stenosis group was 66% ECST, 60% NASCET, and 77% ES. DSA and ES methods were found to have no significant correlation coefficients between DSA and ES methods. in the mild group, the CC was 0. 16 and 0. 13; in the moderate group, the CC was 0. 01 and 0. 01; and in the severe group, the CC was 0. 23 and 0. 10 ; and in the extreme group, the CC was 0. 16 and 0. 10 ; and in the severe group, the CC was 0. 16 and 0. 10. Conclusion DSA and ES methods are both very random when it comes to measuring CS.

Objective The occlusion of cerebrovascular events is a rare occurrence of cerebrovascular events. Since it has patent outflow tract that was provided by patent outer carotid artery from collateral circulation, Riles type 1A CCAO is most likely to profit from revascularization. We described a new surgical approach developed on the basis of the carotid endarterectomy for treatment of Riles type 1A CCAO. Methods We thoroughly screened ten patients with symptomatic Riles type1A CCAO for surgery from January 2017 to May 2019 and then conducted a complete preoperative review of the inadequate collateral circulation compensation. The patch CEA only treated one patient with a history of neck radiotherapy. The average temporary blocking time for treating the upper portion of the common carotid artery was 11. 1 u00b1 2. 64 min.
