[Practical aspects of using different types of angioarchitecture in assessment of brain vascular pathology in patients with circulatory encephalopathy]. / Prikladnye aspekty primeneniia tipov angioarkhitektoniki v otsenke sosudistoi patologii mozga u bol'nykh distsirkuliatornoi éntsefalopatiei.

The article contributes to establishing direct correlative interchanges between MRA and ultrasonic diagnostics data on cerebral arteries perfusion (CAP) in terms of lowering CAP by cerebro-vascular insufficiency type. The data obtained by means of pathomorphological and pathohistological analyses on arterial and venous angioarchitecture, mathematical models of features of vessels branching "geometry" with possible reaction of the vessels to intravascular blood pressure changes, all this can explain variety of trigger zones causing ischemic lesions formation occurred by disgemias of different origins. The issue on cerebral arteries visualization demands from researches to develop more sophisticated methods of MRA to get high resolution ratio and obtain more detailed information about distant segments of cerebral arteries.

[Tactics of treatment of patients with atherosclerotic circulatory encephalopathy]. / Taktyka likuvannia khvorykh na aterosklerotychnu dystsyrkuliatornu entsefalopatiiu.

Immediate and late follow-up results of nonoperative and operative treatment of 244 patients with atherosclerotic dyscirculatory encephalopathy (ADE) were analyzed. The effectiveness of operative treatment is 1.9 times the non-operative one. Surgical correction of ADE of the I-II stages is mostly prognostically favourable. Operative intervention in patients with ADE of the III stage is justified if the operation risk is lower than the risk of disease progress. Indications for the operative treatment in patients with ADE caused by stenosing lesions of the main head arteries are elaborated.

[Reserve possibilities of creating the routes of collateral circulation in stenosing lesions of major arteries of the head]. / Rezervnye vozmozhnosti formirovaniia putei kollateral'nogo krovotoka pri stenoziruiushchem porazhenii magistral'nykh arterii golovy.

The analysis of complex examination of 54 patients with stenosing lesion of the major cephalic arteries by means of Doppler ultrasound, ultrasound scanning, carotid angiography, computerized tomography is presented. The most frequently, two ways of collateral blood flow--via the anterior communicative artery and via the branches of the external carotid artery were revealed. In the first case, ischemia of cerebral tissue is not pronounced, because the anterior communicative artery is functioning in change of a pressure gradient. The second way of collateral blood flow is less reliable, because it is developing slowly and do not provide adequate supply and normal functioning of the nerve cells.
