Dissection of the internal carotid artery is a rare cause of stroke overall, but causes 22% of strokes in younger patients. A common clinical presentation is as Claude Bernard Horner syndrome. We report a craniotomy with 30 degrees rotation of the neck (standard position) in a patient with no major risk factors for carotid dissection, who showed a Pourfour du Petit syndrome due to a dissection ...

abstract: adequate processing of tissues before histologic slices is necessary for preparation of proper histologic sections in animal studies. fixation is one of the most important and early laboratory stages of tissue processing. amount of penetration time of fixator material, into deep layers and central portions of hard tissues, is important factor for prevention of cell lysis. the purpose ...

Carotid intima-media thickness (IMT) has been one widely used index of early carotid atherosclerosis. We speculated that the influence of blood pressure variability (BPV) on early carotid atherosclerosis may be varied by the location of the carotid artery and diabetes history. Thus, the goal of this study was to evaluate the effects of BPV on early arteriosclerosis progression in different segm...
