The diagnostic value of 64-slice spiral CT in Aortic intramural hematoma

Objective:To investigate the value of 64-slice spiral CT (VCT) in the diagnosis of aortic intramural hematoma and its advantages. Methods:32 patients,who complained of acute chest and back pain,underwent continuous volume enhancement scan with 64-slice spiral CT and were diagnosed with aortic intramural hematoma. Results:According to Stanford's classification,32 patients were divided into two types,i.e.,type A with 8 patients and type B with 24 patients. With respect to the direct signs,CT demonstrated the circular or crescentic mass in low density,without intimomedial flap or tear along the aortic wall. As for the indirect signs,CT showed the displaced intimal calcifications in 10 cases,ulceration in 18 cases,aortic atherosclerosis in 8 cases. In addition,3 patients were complicated by pleural effusion.Conclusion:CT angiography,as a non-invasive or minimally invasive modality,can clearly identify aortic intramural hematoma,thereby providing valuable information for the diagnosis and treatment of this disorder in clinic.
