Nghiên cứu giá trị chụp cắt lớp vi tính đa dãy trong chẩn đoán lóc tách động mạch chủ tại Bệnh viện E

Abstract

Objective: The study aims to evaluate some imaging features and value of multidetector computed tomography in the diagnosis of aortic dissection compared with surgery and intervention orientation at E hospital.Subjects and methods: Prospective and retrospective analysis of clinical data and multidetector computed tomography features in 33 patients with aortic dissection at Cardiology Center, E Hospital from February 2020 to June 2021.Results: In the study, there were 33 patients with aortic dissection, the age group from 61-70 accounted for the most, the mean age (62.21±11.42). Male patients accounted for mainly 75.76%. Clinical symptoms and complications were more prominent in the type A aortic dissection group, especially symptoms of chest pain, hypertension, and acute cardiac tamponade. The most common imaging features on computed tomography are endothelium septum (96.96%), pseudovascular lumen diameter>true lumen (96.96%), bird beak sign (96.96%), poor contrast enhancement of the false lumen (80%), and calcification of the lumen (51.51%). The diagnostic value of CT for type A aortic dissection has a sensitivity of 92.9% and a specificity of 100%.Conclusions: Multidetector computed tomography showed high value when describing the characteristics of aortic dissection lesions and good type discrimination to help guide surgery and intervention.
