The term “subclavian steal effect” was introduced in 1961 by Fisher CM. The syndrome develops in case of >60% stenosis or occlusion of proximal part of subclavian artery (before the origin of the vertebral artery) or brachiocephalic trunk. The ve

Cerebral circulation starts from aortic arch vessels (see the diagram in Fig. 1.1). The first artery coming out of the aortic arch is brachiocephalic trunk (TrB), which then divides into right subclavian and right common carotid arteries (CCA). The o

Just as hydrodynamics describe the motion of fluids, especially “ideal” liquid-water, and the interaction of the fluid with its boundaries, hemodynamics studies flow characteristics of blood and its interaction with the walls of the vessels and d

Based on several recent multicenter studies, it was established that only 5–20% of local cerebrovascular disorders caused by atherosclerosis of extracranial arteries develop in the result of hemodynamic disturbances, i.e., reduction of blood flow i

Such factors as cerebrovascular reserve, condition of cardiac hemodynamics, systemic blood pressure, and rheological parameters of blood have a big influence on cerebral circulation.

Atherosclerosis of arteries may develop in the result of a number of risk factors, like hypercholesterinemia; arterial hypertension; smoking; diabetes mellitus; obesity; psychological, emotional, and hereditary factors; gender; and age. Evidence of a

Congenital variations of extracranial arteries include fenestration and duplication, variations in the caliber (reduction of sizes, hypoplasia, and widening, dilation). Apart of that, quite a rare anomaly is aplasia. Abnormal course of arteries inclu

Dissection of extracranial arteries is one of the most important reasons of ischemic stroke in young people. A community-based study showed an incidence of neck vessel dissections of 2.6 per 100,000 per year. Dissections are most common between the a

MRA and CTA two-dimensional (2D) images are assessed by standard methods described above. The majority of standard CT studies are performed in axial plane, which gives relatively poor information about hemodynamics. In comparison with conventional CT
