ULTRASOUND DIAGNOSTICS OF THE ARTERIOVENOUS CEREBRAL DISCIRCULATION  

1) permeability of the brain arteries and veins ;

2) elastic and tonic properties of the arteries and veins;

3) reorganization of arterial and/or venous cerebral circulation;

4) adaptable opportunities of the arterial and venous collateral circulation;

5) individually selected effective and pathogenically substantiated medicine,

1) make an objective analysis of patients’ complaints on early stages of diseases in out-patient and in-patient conditions;

2) discover an additional potential of the clinical revealing of a cerebrovascular pathology;

3) study a compensatory potential of the cerebral hemodynamics and its realization in all disease stages of patients at different ages;

4) study a degree of the cerebral hemodynamic reconstruction and reveal the neurological deficiency under influence of medical treatment and angioreconstructive operations;  

“Way of the ultrasound diagnostics of a condition of the brain vessels”)

We propose to perform a clinical interpretation of dopplerograms by the following directions:    

 2. Stability of the cerebral circulation:

 3. Lack of the cerebral arterial blood flow

 · According to the location:

· According to expressive signs:

· Normal tonus is an optimum variant for the stable hemodynamic characteristics;

· Distorted tonus is a risk factor of reducing of the arterial lumen and appearance of the turbulence:

a. Dystonia;

b. Angiospasm:

c. Hypertonus.

2. Elasticity of the arterial wall:

· Preserved – it provides an adequate reaction of the vascular wall on the hydraulic strokes;

· Distorted – it causes paradoxical transformations of the hemodynamic picture due to an inadequate reaction of an injured vascular wall:

a. Early signs of aging of the vascular wall;

b. Slightly decreased;

c. Considerably decreased;

d. Of the sclerotic – hypertonic type;

e. Of sclerotic type.

USDG-criteria for the disturbance of functioning of the venous cerebral link, quantitative and qualitative assessment of an adequacy of the venous outflow from the brain; 

· Continuous;

· Intermittent.

· Preserved – normal tonus;

· Distorted:

1. Hypertonus;

2. Hypotonus;

3. Dystonia:

a Compensatory;

b Subcompensatory;

c Decompensatory with retrograde throwing.

 2. Condition of reserve collateral tracts of the outflow

· Normal;

· Compensatory overload:

1. Adequate;

2. Insufficient.

 Assessment of the sufficiency of the pumping function of the myocardium for blood supply for the brain    

1. Pumping function of the myocardium is:

· Preserved;

· Age physiological;

· Age pathological;

· Reduced in left sections;

· Reduced in right sections.

2. Condition of the heart valve:

· Without any peculiarities;

· Functional insufficiency of the aortic, mitral valve:

1. Moderately expressed;

2. Considerably expressed;

3. Hemodynamically important for the cerebral circulation

 Condition of the arterial-venous-liquor balance and determination of dominating causes of the intracranial hydrodynamic conflict:

 1. Preserved:

· physiological,

· pathological.

2. Distorted and displaced towards:

· arterial hyperemia;

· venous congestion.

 Presence of the pathological arteriovenous shunting:

1. Absent

2. Present:

· According to the location,

· According to the size,

· According to the intensiveness
