objectives in this study, we aimed to investigate the changes in brain lipidomics following prolonged and intermittent ischemic preconditioning. materials and methods two groups underwent bilateral common carotid artery occlusion either intermittently (for 3 continuous periods within a timeframe of 20 minutes, releasing 3 consecutive times, yielding a total of 9 minutes (intermittent bilateral ...

background: the presence of significant carotid stenosis in coronary artery bypass grafting (cabg) patients increases the risk of either transient ischemic attack or stroke. however, there is a dearth of data on the risk for patients with unilateral total occlusion of the carotid artery. we herein report our results of cardiac surgery in patients with unilateral total occlusion of the carotid a...

one of the signifiant risk factor of ischemic stroke is carotid artery occlusion. although surgical treatment was disappointing in these patient but there is a growing reports of sucessful endovascular treatment recently. in this technical note 56 year-old man who suffered from bilateral carotid occlusion was revascularized. the penumbra thrombosuction system was applied to reduce the risk of d...

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...

Introduction: The aim of this study was evaluation the effects of bilateral carotid artery occlusion on cochlear oxidative stress and hearing status in rat. Methods: The rats were divided into two sets. First set used for electrophysiological recording (click and 4 kHz tone burst ABR and EcochG) at day before surgery and 1st, 4th and 7th days after surgery. Animals of second set that used for ...

Objective(s):The present study investigated the effect of long-term mild cerebral hypoperfusion induced by permanent unilateral (right) common carotid artery occlusion (UCO) on the dorsal hippocampal neurons in rats. Materials and Methods:Sixty four male Sprague-Dawley rats aged 4 months were divided into two groups of sham and UCO. These two groups were further divided into 4 sets of histopath...

Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...

Background: Recent studies suggest that prolonged and intermittent bilateral common carotid artery occlusion (prolonged bilateral common carotid artery occlusion (PO) and intermittent bilateral common carotid artery occlusion, respectively) can lead to reduced ischemia brain injury in ischemic tolerance. Objectives: In this study, we aimed to investigate the changes in brain lipidomics followin...

objective(s):the present study investigated the effect of long-term mild cerebral hypoperfusion induced by permanent unilateral (right) common carotid artery occlusion (uco) on the dorsal hippocampal neurons in rats. materials and methods:sixty four male sprague-dawley rats aged 4 months were divided into two groups of sham and uco. these two groups were further divided into 4 sets of histopath...

We retrospectively studied 46 patients with symptomatic retinal artery occlusion and assessed the pattern and extent of carotid artery disease ipsilateral to the retinal artery occlusion. Ipsilateral internal carotid artery atherosclerotic lesions were virtually limited to the cervical arterial segment; 50% of such lesions were plaques or stenoses of less than or equal to 60%, whereas 15% of th...
