[Transcranial dopplerography in the optimization of the treatment procedure in cerebral arteriovenous malformations taking into account the functional cerebral hemodynamics].
The incidence of vascular abnormalities in the pattern of central nervous diseases is steadily increasing. Arterioventricular malformations (AVM) are of great significance among cerebrovascular diseases to be surgically treated. A comprehensive examination of 57 patients with AVM, which involved cerebral angiography, transcranial Doppler at the stages of surgical treatment led to the conclusion that the application of AVM morphological characteristics alone did not allow the development of specific complications, hyperemic ones in particular, to be accurately predicted in the early postoperative period after elimination of malformation. It was suggested that due to the naturally significant relationship of Doppler indices of blood flow in the nutrient arteries having structural malformations and showing cerebral circulatory disorders, the use of values of the linear velocity of blood flow in and the reactivity and resistance in the nutrient arteries enables one to predict a risk for hyperemic complications after AVM elimination to a high precision and to define a preferable surgical intervention. The priority employment of transcranial Doppler in the diagnostic examination of patients with AVM will optimize an instrumental preliminary study, make a correct treatment policy, improve the outcomes of surgical intervention, and reduce the length of hospital stay.
