Abstract

This study comprised 16 patients with aortic dissecting aneurysm who were admitted to Seoul NationalUniversity Hospital from May 1984 to Jannuary 1987. CT findings in 16 cases of aortic dissecting aneurysm werecorrelated with angiographic findings retrospectively. The results were analysed. 1. Number of male was 11 andthat of female was 5. Male patients in fifties were most common and 4 in number. 13 patients had hypertension ofhistory of hypertension among 14 patients. There were one case of Marfan's syndrome, preeclampsia and Takaysu'sarteritis respectively. 2.There were 5 cases of DeBakey type 1, 1 case of type II and 9 cases of types IIIdissecting aneurysm. Type III was most common. 3. CT confirmed as superior vena cava which was not identifiedwhether it was superior vena cava or unopacified false lumen by angiography in one case. Regarding distal extent,authors defined a whose extent was proximal to diaphragm and B beyond it for convenience sake. There was one falsenegative case in CT among 16 cases which was diagnossed as dissecting aneurysm type IIIB by angiography andconfirmed as type III surgically. One case was diagnosed as type IB by CT and as type IIIB by angiography andconfirmed as type I surgically. Extent was more accurate in CT than angiography. One case was diagnosed as type IIby CT but misdiagnosed as right atrial tumor by angiography. 4. Diagnositc sensitivities of CT and angiography inthis study were 94%(15/16) respectively. CT was more advantageous in hemothorax, hemopericardium, hemomediastinum,unopacified false lumen, aortic wall calcification and getting informations about mediastinum. In angiographyaortic regurgitation and tear site and involvement of abdominal vessels could be observed.
