The carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. The aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in Makouei sheep. Fourteen heads of sheep from both sexes were collected from Urmia public slaughter-house. The exact situation and nerve supply of ...

A 78 year-old women presenting at the Emergency Department with a painful, palpable tumour in the left mandibular angle of one month’s evolution. She had no history of trauma, surgery or regional infection. Intravenous contrast computed tomography revealed a collection of 5.2 cm in the left carotid space, with a thick wall with high uptake (Fig. 1: arrows), gas in its interior and with no commu...

Animal models are essential for understanding the pathology of stroke and investigating potential treatments. However, in vivo stroke models are associated, particularly in mice, with high variability in lesion volume. We investigated whether a surgical refinement where reperfusion is not reliant on the Circle of Willis reduced outcome variability. Mice underwent 60 min of transient middle cere...

However, in vivo stroke models are associated, particularly in mice, with high variability in lesion volume.

The objective of the study was to investigate the feasibility of using computational fluid dynamic modeling (CFD) with noninvasive ultrasound measurements to determine time-variant three-dimensional (3D) carotid arterial hemodynamics in humans in vivo. The effects of hyperoxia and hypoxic hypercapnia on carotid artery local hemodynamics were examined by use of this approach. Six normotensive vo...
