The Diagnosis of Multi-Slice Spiral CT Angiography in Acute Intramural Hematoma Associated with Penetrating Aortic Ulcer

Objective To evaluate the value of multi slice spiral CT angiography in the diagnosis of acute Intramural hematoma(IMH) associated with penetrating aortic ulcer.Methods Twenty cases of IMH associated with PAU were examined with MSCT.Two dimensional and three dimensional imags were analyzed.Results Twenty cases were divided into Stanford A type(n=5) and Stanford B type(n=15).True and flase lumen,intimal flap were not be shown,and IMH were associated with penetrating aortic ulcer in all cases.crescent or circular thickening of aorta wall were found in IMH,as well as displacement of intimal calcification(12 cases),pleural effusion(8 cases),pericardial effusion(4 cases).There were 28 lesions of penetrating ulcer were found in 20 patients,in which u1cer like aortic projections were observed.There were 22 lesions of PAU in 14 patients(79%),and 6 lesions of ULP in 6 patients(21%).Conclusion Multi slice Spiral CT Angiography is an effective method for the diagnosis of acute Intramural hematoma(IMH) associated with penetrating aortic ulcer by providing valuable information for the diagnosis and treatment.
