Opacity Pulse Propagation in Internal and External Carotid Vascular Beds of Experimental Animals • Opacity pulses and opacity pulse propagation times were recorded from the external carotid arterial bed (ear) and from the ipsilateral internal carotid arterial bed of the pial-cortical surface within the closed skull of conscious monkeys and anesthetized cats during the resting state and during c...

A 68-year-old man presented with occlusion of the internal carotid artery (ICA) manifesting as a 6-month history of progressive sensory and motor disturbance of the left lower limb. Angiography clearly demonstrated a collateral arterial network between the ICA and external carotid artery (ECA) through the vidian artery, a small branch of both the ICA and ECA. The vidian artery may form an unusu...

Stroke is one of the common causes of death and disability in the world. The intraluminal middle cerebral artery occlusion/reperfusion (MCAO/R) model is a "gold standard" in surgical ischemic stroke models. Here, we optimized the procedure of this model by ligating on external carotid artery (ECA) stump and two ligatures prepared on internal carotid artery, which could improve the success and s...

OBJECTIVES Extracranial carotid artery true aneurysm is extremely uncommon, and definite treatment has traditionally involved open surgical repair. Although successful management of the internal carotid artery aneurysms using endovascular stenting and embolization has recently been reported, only a limited number of cases have been reported. METHODS We present a case of symptomatic carotid tr...

A parametric computational model of the human carotid artery bifurcation is employed to demonstrate that it is only necessary to simulate approximately one-half of a single heart pulse when performing a global exploration of the relationships between shear stress and changes in geometry. Using design of experiments and surface fitting techniques, a landscape is generated that graphically depict...

Background & aim: To identify the variations in site of origin and level of the origin of the superior thyroid artery and its relation with external laryngeal nerve. Material & Method: A study was undertaken on 33 donated cadavers and through dissection was performed in neck region and both sides of superior thyroid artery were considered. Results: in present study superior thyroid artery arise...

The characteristics of physiological blood flow in human carotid arterial bifurcation model have been numerically studied using a fully coupled fluid-structure interaction (FSI) analysis. This computational model with the fluid-structure interaction is constructed to investigate the flow characteristics and wall shear stress in the carotid artery. As the flow begins to decelerate after the peak...

Many authors have studied variation in the maxillary artery but there have been inconsistencies between reported observations. The present research aimed to examine the courses and branching patterns of the trunk and branches of the maxillary artery in a large sample of Japanese adult cadavers. The course of the maxillary artery should be reclassified into seven groups as a clear relationship w...

The results for blood flow in the carotid artery bifurcation on the basis of numerical simulation of Navier-Stokes equations are presented in this study. Four cases of carotid bifurcation are considered: common carotid artery (CCA) bifurcation without stenoses and cases with one, two and three stenoses are also presented. The results are obtained by performing numerical simulations considering ...
