To evaluate the changes of cerebral perfusion we studied 41 patients with moderate and severe carotid stenosis before and after surgical or endovascular treatment. Perfusion CT at the level of basal ganglia was performed in 17 patients with moderate (50–69%) and 24 patients with severe (70–99%) carotid stenosis for 3 times: before intervention (transluminal angioplasty with stenting or carotid endarterectomy), 3 to 7 days and 1 to 3 months after treatment. Additionally, single CT perfusion study was done in 39 patients without carotid stenosis (control group). We found that surgical recanalization of internal carotid artery may aid restoring cerebral blood flow characteristics in the MCA area to the levels similar to those in control group (namely, decrease of MTT and CBV and increase of CBF). However, in anterior and posterior watershed zones, which are known to be the most vulnerable by chronic hypoperfusion, blood flow normalization was seen only in patients with complete circle of Willis and with moderate carotid stenosis.Thus, prognostic factors for inadequate blood flow restoration in patients with carotid artery stenosis after revascularization include severe stenosis (&gt;70%) and incomplete circle of Willis.</p></abstract><trans-abstract xml:lang="ru"><p>Изменения церебральной перфузии и состояние коллатерального кровоснабжения при стенозах внутренних сонных артерий могут иметь прогностическое значение для восстановления кровотока при проведении реваскуляризационных вмешательств на внутренних сонных артериях (ВСА). С целью определения закономерностей изменения перфузии мозга у пациентов со стенозами ВСА было проведено клинико-КТ-перфузионное исследование 41 пациента с умеренными и выраженными стенозами ВСА до и после хирургического лечения. Перфузионная компьютерная томография (ПКТ) проводилась 17 пациентам с умеренными стенозами ВСА (50–69%) и 24 пациентам с выраженными стенозами ВСА (70–99%) до хирургического вмешательства (баллонной ангиопластики со стентированием или каротидной эндартерэктомии), после операции на 3–7-й день и через 1–3 месяца; сканирование проводилось на уровне базальных ганглиев и семиовальных центров. У пациентов без стенозирующего поражения ВСА (контрольная группа – 39 чел.) ПКТ проводилась однократно. В результате исследования установлено, что хирургическое восстановление просвета ВСА приводит к нормализации параметров мозгового кровотока в зоне кровоснабжения средней мозговой артерии, что проявляется снижением параметров MTTи CBV и повышением CBF до значений, сопоставимых с контрольной группой. При этом в зонах переднего и заднего смежного кровоснабжения, наиболее страдающих в условиях хронической гипоперфузии, восстановление церебральной перфузии происходит только у пациентов с замкнутым виллизиевым кругом (ВК) и при умеренно выраженном атеросклеротическом поражении ВСА. Таким образом, прогностическими факторами неудовлетворительного восстановления кровотока у пациентов со стенозами ВСА являются наличие выраженного стеноза ВСА (&gt;70%) и незамкнутый ВК.</p></trans-abstract><kwd-group xml:lang="en"><kwd>CT perfusion</kwd><kwd>cerebral perfusion</kwd><kwd>cerebral hemodynamics</kwd><kwd>carotid artery stenosis</kwd><kwd>carotid artery revascularization</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>перфузионная КТ</kwd><kwd>перфузия мозга</kwd><kwd>церебральная гемодинамика</kwd><kwd>стеноз внутренней сонной артерии</kwd><kwd>реваскуляризация внутренних сонных артерий</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Верещагин Н.В., Мусатова И.В., Пирадов М.А.Радиоизотопный (133Хе) ингаляционный метод определения регионарного мозгового кровотока.
