The Analysis Of Characteristics Of And Atypical Presentation In84Patients With Aortic Dissection

Objective: To investigate the atypical presentation of aortic dissection(AD) in order topromote the understanding of this disease.Methods:We collected cases of aortic dissectionwhich presentations were atypical between2002and2011,and retrospectively analysedtheir clinical manifestation.Results: A total of84patients with aortic dissection,including63male,21female were enrolled.According to the Stanford classification,there were47patients of Stanford type A and37patients of type B.There were59patients withhypertension,10patients with diabetes,3patients with Marfan’s syndrome.40patients hadsmoking history,the proportion of smoking patients in Stanford type A was significantlyhigher than that in type B（48.9％vs45.9％，p=0.040）.There were no significantdifferences between type A and type B in ages,gender and morbidity ofhypertension,diabetes, Marfan’s syndrome.25patients were performed operation, theproportion of operative patients in Stanford type A was significantly higher than that intype B（48.6％vs14.9％，p＝0.027）.Atypical presentation included abdominal pain（n=48）,lumbago （n=15）,acute myocardial infarction （n=6）,paraplegia（n=1）,extremity numbness and weakness （n=2）,dizziness （n=3）,syncope（n=6）,hemiplegia and slured（n=3）.Conclusion: The aortic dissection dissection hasvaried and complicated presentation,so it’s easy to make misdiagnosis and misseddiagnosis.Therefore,clinicians should improve their understanding of the aortic dissectionin the hope of early diagnosis and treatment.
