[Surgical management of stenosing lesions of carotid arteries based on comparative results of an ultrasonographic and angiographic study].

Surgical treatment of stenosing lesions of carotid arteries has proved to be a reliable method of prevention and management of chronic cerebrovascular insufficiency. The purpose of this study was to assess the diagnostic possibilities of duplex scanning from the position of an isolated diagnostic method for safe and efficient reconstruction of carotid arteries. The study comprised 177 patients presenting with occlusive-and-stenotic lesions of carotid arteries, who underwent a total of 204 reconstructive operations. We believe that duplex scanning alone may safely be considered sufficient to make a definite diagnosis of carotid arteries stenosis in the overwhelming majority of the patients involved. The indications for reconstructive operations on carotid arteries are largely predetermined by the degree of stenosis, structure of the plaque, and the condition of its surface, as well as by the presence or absence of the <> of the plaque. The outcomes of reconstructive operations carried out on carotid arteries based on the findings of duplex scanning do not significantly differ from the outcomes of the operations performed on the basis of angiographic data.
