THE ROLE OF COMPUTER TOMOGRAPHY AND MAGNETIC RESONANCE IMAGING OF THE BRAIN IN THE DETERMINATION OF THE TACTICS OF TREATMENT OF CRITICAL DAMAGE OF BRACHIOCEPHALIC ARTERIES IN THE PREAND POSTOPERATIVE PERIODS
The aim of the present study is to study the role of CT and MRI of the brain to determine the indications for surgical treatment of critical carotid stenosis. Material and methods. A.N. Bakoulev Scientific Center for Cardiovascular Surgery of Russian Academy of Medical Sciences was held 117 (100 %) research CT and MRI of the brain at different stages of the formation of ischemic changes in the parenchyma. Of them brain CT scan performed in 93 (79.5 %), and MRI and 24 (20.5 %) patients. Results. From the obtained data revealed that 98 % (83.8 %) patients had changes in the parenchyma of the brain in the stage of organization. Acute and subacute stage of cerebral ischemia was 19 (16.2 %) cases. CT and MRI research identified ischemic lesions in different time intervals and at different stages of their transition from the development of necrosis in the parenchyma to the formation of cysts with fibrous capsule. Conclusions. Clinical applications of CT and MR angiography studies, as well as various computer programs for processing and reconstruction of the obtained data allows to be able to select adequate diagnostic and treatment tactics. The use of advanced hardware and software of modern scanners allows to reliably diagnose almost all types of cerebrovascular disease, determine the indications for further treatment and monitor the adequacy of the performed manipulations. Analysis of the results of all methods of examination determines the tactics of surgical treatment in a planned or urgent.
