Abstract:Objective: To observe the differential diagnosis effect of super mircovascular imaging (SMI) in Stanford B aortic dissection patients with true and false lumen and abdominal aortic branch artery involvement. Methods:Retrospective analysis was performed on the data of 100 patients with Stanford B aortic dissection admitted to Dandong First Hospital from December 2015 to December 2020,and, according to different imaging diagnosis methods, they were divided into SMI group (60 cases) and conventional ultrasound group (40 cases), both with digital subtraction angiography (DSA) as the "gold standard". True and false lumen, and abdominal aorta branch artery involvement were identified in both groups. Results: The coincidence rate of differential diagnosis of true and false cavities in SMI group (96.67%) was significantly higher than that of conventional ultrasound examination group (62.50%), and the difference was statistically significant (χ2=10.427, P<0.05); the coincidence rate of diagnosis of abdominal aortic branch artery involvement in group SMI group (83.33%) was significantly higher than that of conventional ultrasound examination group (65.00%), and the difference was statistically significant (χ2=4.423,P<0.05). Conclusion: Compared with conventional ultrasound diagnosis, ultrasonic super mircovascular imaging technology is used more accurately in the diagnosis of Stanford B-type aortic dissection, which can identify the true and false lumen of patients with aortic dissection and detect the involvement of abdominal aorta branch arteries in patients with aortic dissection, and the diagnostic coincidence rate is higher, which can provide a valuable basis for clinical diagnosis and treatment and prognosis evaluation.
