Diagnostic Value of 64 slice spiral CT Angiography in Aortic Dissection

Objective To investigate the value of 64 Multi-Slice Spiral CT angiography in the diagnosis of aortic dissection and analyze.Methods During the period from 2010 March to 2012 December in our hospital 64 row helical CT in treatment of 50 cases of aortic dissection in patients with clinical data were retrospectively analyzed and summarized.Results According to Debakay classification,50 patients with aortic dissection,15 cases of type I patients,patients with type II 11 cases,type III patients of 24 cases.All patients can clearly see clear break,true and false cavity and low density linear intimal flap,false lumen diameter is 47mm,the true lumen diameter minimum 5mm,21 patients can see the mural thrombus in the false lumen.In addition,in 50 patients with aortic dissection,5 patients with aortic dissection involving the brachiocephalic trunk,4 cases involving the left subclavian artery,6 cases involving the celiac trunk,5 patients with superior mesenteric artery,14 cases involving the common iliac artery and its branches.Conclusion Evaluation of aortic dissection 64 row helical CT angiography has high accuracy,a preferred imaging method can be used as a diagnostic screening suspected aortic dissection.
