Мультиспиральная компьютерная томография в выявлении признаков нестабильности стенки аневризмы аорты

Мультиспиральная компьютерная томография в выявлении признаков нестабильности стенки аневризмы аорты

Abstract

Актуальность. Аневризма аорты - распространенное заболевание с полиморфной клинической картиной и внезапным риском развития тяжелых осложнений. Цель - разработка стандартизованного протокола мультиспиральной компьютерной томографии (МСКТ) у пациентов с подозрением на аневризму аорты и определение признаков нестабильности стенок аневризмы. Материал и методы. В течение 2009-2014 гг. было обследовано 279 пациентов с аневризмой аорты. Всем пациентам проводилась МСКТ по специализированному протоколу с последующим комплексным анализом полученных результатов. Результаты. Осложненное течение аневризмы аорты выявлено в 100 (36%) случаях, самым частым признаком нестабильности стенок аорты стала диссекция. Сформулировано новое комплексное понятие осложненного течения аневризмы аорты, включившее в себя признаки нестабильности стенок аневризмы без полного нарушения целостности стенок и с полным нарушением целостности. Создана схема рентгенологических паттернов, характеризующих состояние стенок аневризмы. При описании изменений в стенках аорты эта схема позволяет достичь высокой точности, сопоставимой с гистологическими данными. Заключение. Использование стандартизованного протокола исследования и описания полученных результатов способствует значительному повышению качества лучевой диагностики аневризмы аорты.

Background: Aortic aneurysm is characterized by high incidence, polymorphic clinical features and sudden onset of severe complications. Aim: To develop a standard multidetector computed tomography (MDCT) protocol for aortic aneurysm examination and image analysis for detection the signs of aortic wall instability. Materials and methods: The data of 279 patients with aortic aneurysm who underwent MDCT examination during 2009-2014 was analyzed to identify aortic wall instability signs. Results: Complicated course of aortic aneurysm was observed in 100 cases (36%). The most common sign of aortic wall instability was aortic dissection. According to our results, a new definition of aortic aneurysm complications was elaborated. It included signs of aortic wall instability with incomplete and/or complete disruption of aortic wall layers. A scheme of the most common patterns of aortic wall abnormalities was proposed, allowing a radiologist to reach high accuracy in characterizing this pathology. Conclusion: A dedicated MDCT protocol for aortic aneurysm detection and image analysis can increase quality of radiologic assessment of aneurysm wall allowing to approach to the level of histological accuracy.
