Surgery is an effective method to correct and prevent cerebrovascular insufficiency progress in chronic cerebrovascular disease, in particular occlusive−stenotic pathology of the brachiocephalic artery. Its main purpose is to increase the flow of blood to the brain tissue in the areas with hypoperfusion, which prevents stroke development. The most widely used and most common methods aimed at improving cerebral circulation in this pathology are carotid endarterectomy and creation of extraintracranial microvascular bypass. To evaluate the results of the study of cerebral hemodynamics in patients with occlusal−stenotic pathology of the brachiocephalic arteries before and after creation of extraintracranial microvascular bypass with perfusion multispiral computed tomography and duplex vascular sonography of the head and neck, the results of surgical treatment in 12 patients were analyzed before and after microvascular bypass placement. Effectiveness of surgical intervention was evaluated according to the data of neuropsychological examinations, duplex sonography of the head and neck vessels, multispiral computed tomography, selective cerebral angiography. Extraintracranial bypass was created between the superficial temporal and middle cerebral arteries. Extraintracranial bypass efficacy was confirmed by the data of case history and cerebral perfusion results. Perfusion multispiral computed tomography and duplex sonography of the head and neck vessels are important methods for detecting hemodynamically significant pathology of cerebral vessels at the preoperative stage in patients with steno−occlusive pathology of the brachiocephalic arteries in monitoring the cerebral hemodynamics state in the postoperative period with the purpose to evaluate the long−term results of surgical correction
Key words: neuroradiology, perfusion computed tomography, duplex ultrasound, stenotic−occlusive pathology of the brachiocephalic artery, vascular surgery.
