The diagnostic value of MSCT on diagnosis and prognosis evaluation of abdominal aortic aneurysm / 实用放射学杂志

ABSTRACT

Objective To evaluate the diagnostic value of MSCT in abdominal aortic aneurysm(AAA).Methods 26 patients suspected AAA and admitted to our hospital were studied and checked by MSCT prospectively.The accuracy and features of MSCT were analyzed. Results 26 patients were diagnosed as AAA by MSCT,in which 17 cases were true AAA,and 9 were false AAA.MSCT for true AAA patients showed fusiform dilatation of abdominal aorta bulging to the left,and showed visible thrombus and calcification in aneurysm wall of residual tumor around the cavity when aneurysm ruptured.MSCT of false AAA showed aortic eccentric enlargement lump,which could be outside the boundaries of vascular calcification.25 cases of AAA were surgically confirmed,and the coincidence rate of MSCT and pathology was as high as 96.1% (25/26).Arterial wall calcification was found in all patients,in which 17 cases had mural thrombus.Conclusion MSCT is a safe,effective and non-invasive diagnostic technology for early detection and treatment of AAA, which may help determine patient’s condition and guide the treatment.
