We examined 97 patients aged 14 days - 21 years with coarctation of the aorta (CA) and studied effect of high pressure and pressure gradient in the region of CA (DeltaP(CA)) on cardiac pump function and reserve capacity of the left ventricle. Children with left ventricular (LV) ejection fraction (EF) below 30% (n=24) comprised group 1, patients with LVEF 30 - 45% (n=55) - group 2, and patients with LVEF above 45% - group 3. Four group 1 patients had signs of fibroelastosis of the left ventricle, 3 of them were operated before age of 3 months, 1 - at the age of 5 months.

[Clinical, structural-functional and haemodynamic correlates of cerebral venous blood circulation disturbances].

Difficulties of liquor circulation as a result of cerebrospinal fluid absorption and venous drainage of the entire intracranial space, in particular in the presence of venous system abnormalities in the forms of hypoplasia or aplasia of venous sinuses, play an essentiale role in cerebral venous dyscirculation. The symmetric character of hydrocephaly in chronic insufficiency of cerebral blood circulation and strong dependence of chronic cerebrovascular insufficiency on passive congestion suggest that the latter is characteristic of the blood supply system in whole. The MPI analysis of 120 patients revealed signs of cerebral ischemic lesions in 72% of cases, i.

[State of cerebral circulation in patients with essential arterial hypertension].

In order to evaluate the volumetric flow rate of the blood in the major extracranial arteries, as well as to assess intracranial haemodynamics in patients presenting with isolated arterial hypertension and those with haemodynamically insignificant pathologies of the "CA" the authors analysed the findings obtained in a total of 159 patients (71 males and 88 females) who were diagnosed with mild, moderate and severe arterial hypertension. The average age of the patients amounted to 59 +/- 12 years. Studying the thickness of the intima-medial complex of the common carotid artery in both isolated arterial hypertension (AH) andAH combined with atherosclerotic alterations in the CA demonstrated its thickening, which was more evident in a combination of atherosclerosis with AH.

Hemodynamic physiology in aortic arch and trigger factors of atherosclerosis.

Magnetic resonance angiography showed that blood flow in the aortic arch during protodiastole is separated into the opposite flows, which are temporarily arrested at the certain sites creating the flat front of the flow. The protodiastolic antegrade peak acceleration 6-fold surpasses the systolic one. Due to adhesion, the high gradient pressure forces can damage the vascular wall.

[Ischemic stroke and the ways of compensation of cerebral circulation in patients with nonspecific aorto-arteritis with lesions of the brachiocephalic arteries].

In patients suffering from nonspecific aortoarteritis associated with impairment of the common carotid arteries, cerebral blood flow is compensated for at the expense of an increase of the volumetric blood flow in the vertebral arteries. During the first three years since the onset of the first disease symptoms, the blood content in the basin of the internal carotid arteries is reduced. Brain strokes occur most frequently within that period.
