BACKGROUND AND PURPOSE The computerized occlusion rating to estimate angiographic occlusion of embolized aneurysms is superior to the subjective occlusion rating. In this study, we compared the 2 methods in the analysis of aneurysms clipped after subarachnoid hemorrhage. MATERIALS AND METHODS The pre- and postoperative angiographic images (DSA) of 95 selected patients were analyzed and strati...

Occlusion between objects is one of the overlooked challenges for object detection in UAV images. Due to variable altitude and angle UAVs, occlusion images happens more frequently than that natural scenes. Compared scene images, with feature confusion problem local aggregation characteristic. And we found extracting or localizing beneficial detector address this challenge. According finding, lo...

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...

purpose: doing plyometric training with and without the vessel occlusion is an effective practice for rapid increase of muscles strength their hypertrophy. we evaluated the effects of plyometric training with and without the vessel occlusion on electromyographic parameters. methods: in this quasi-experimental study, 22 females were selected through convenience sampling method. they were randoml...

An occlusion of the artery Percheron (AOP) is a rare clinical condition that remains diagnostic challenge for physicians given its variable presentation. This infarction result an anatomical variant single vessel arising from posterior cerebral artery. Occlusion AOP results in levels alteration consciousness, vertical gaze palsy, and memory impairment. Unfortunately, due to this presentation th...

introduction: there are two basic types of vein occlusion, branch retinal vein occlusion (brvo), in which one of the branches of the main vein is blocked, and central retinal vein occlusion (crvo) in which the main vein of the eye is blocked.  vein occlusions are associated with various illnesses and often occur in elderly. the etiological causes of these diseases in the young people remained c...

results in all groups ischemic changes were apparently observed in hippocampus ca1 neurons. in two-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 14.9% and 23.2%, respectively. in four-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 7.6% and 44.9% (p < 0.0001), respectively. background an appropriate animal m...

Injection of synthetic fillers for soft tissue augmentation is increasing over the last decade. One of the most common materials used is hyaluronic acid (HA) that is safe and temporary filler for soft tissue augmentation. We present a case of 54-year-old female who experienced vascular occlusion and nasal alar necrosis following HA injection to the nasolabial folds. She suffered from pain, necr...

Retinal vein occlusion is one of the vascular disorders affecting vision. Branch retinal vein occlusion and central retinal vein occlusion are the two basic types of vein occlusion. Branch retinal vein occlusion is three times more common than central retinal vein occlusion and is second only to diabetic retinopathy as the most common retinal vascular cause of visual impairment. The origin of b...

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...
