Abstract:
Objective To improve recongnition of CT manifestations and value in diagnosing aortic dissection and rupture.Methods The CT plain and enhanced findings in 16 cases with aortic dissection were analyzed retrospectively,these 16 cases were classified in to DeBakey type Ⅰ?Ⅱand Ⅲ in 2,4 and 10,in which 3 cases had subacute and chronic rupture.Results Among these 16 patients with AD,the aortic double lumen and intimal flap,6 cases were showed minor calcifications in the dissection membrane,3 cases were acute rupture or slow leakage complications including periaortic mediastinal,pericardiac pleural or retroperitoneal effusion and retroperitoneal diffuse fibrosis.Conclusion CT is a helpful reliable and rather simple technique for AD lesion and complication.It should be suggested if a diffuse fibrosis occure in retroperitoneal space complicating with chronic permeability of AD.
