Abstract:
Objective To investigate the clinical value of multi-slice spiral CTA ( MSCTA ) and image-post processing techniques in diagnosis of acute aortic syndrome ( AAS) .Methods 71 patients with AAS were scanned by TOSHIBA Aquilion 64-slice spiral CT,the images on axial and 2D/3D were analyzed.Results 71 cases included 48 cases of aortic dissection ( AD) ,10 cases of intramural hematoma ( IMH) and 13 cases of penetrating atheroscle-rotic ulcer ( PAU) .MSCT depicted the imaging features of AAS:AD showed intimal flap and true and false lumens;IMH showed crescent or circular thickening of aortic wall .PAU showed a niche filling with contrast medium and pro-truding the aortic lumen ,where narrow neck signwas shown .The location ,radiological diagnosis and complications of AAS were observed in 71 patients.Intervention treatment or surgical treatment was conducted in 27 cases after defi-nite diagnosis .Conclusion MSCT is a fast and noninvasive examination technique , and it can provide important information for the diagnosis and treatment of AAS .
