Abstract:
Objective To analyze the diagnostic and clinical characteristics of aortic dissection (AD) and to evaluate the imaging findings and their clinical significance. Methods The clinical characteristics and imaging findings in 32 AD patients were analyzed retrospectively. Results Hypertension was the primary pathogen for AD. The first and main symptoms included acute chest and back pain. Chest X ray examination was the screening method for AD. Computerized tomography (CT) and transthoracic echocardiogram (TTE) had higher sensitivity, and magnetic resonance imaging (MRI) had the highest accuracy. Digital subtraction angiography (DSA) was performed mainly for preoperative diagnosis or endovascular graft exclusion. Conclusion The clinical characteristics of AD include sudden onset, high risk, and varied and complicated clinical manifestations. Option of one or all of the chest X ray examinations, including TTE, CT, MRI, and DSA, may be the most important method for the diagnosis of AD.
