Abstract:
Objective To discuss risk factors,clinical characteristics and associated prognostic factors of acute aortic dissection with different Stanford classification.Methods Retrospective analyses were conducted on clinical data of 162 patients with acute aortic dissection in China-Japan Friendship Hospital.The data was analysed according to Stanford type,risk factors,clinical manifestation,auxiliary examination.Prognostic factors of acute aortic dissection were analysed by single factor and binary logistic regression analysis.Result Of all the acute aortic dissection patients,the mean age was (53.9 ± 13.5) years (foreigners' mean age was 61.0 years),87.0％ were less than 65.0 years old,males were younger than females,77.2％ presented hypertension.Application of Latex (＜0.5 mg/L) and ELISA (0 ～400 ng/mL) methods to detect D-dimer,the sensitivities were 90.9％ and 94.7％ respectively,and the general sensitivity was 93.2％;91.5％ patients were abnormal when detected by ultrasound (echocardiography),of which the sensitivity of A type was 100％,so it can be the first choice of hemodynamic instability patients,at the same time can be used for differential diagnose between acute myocardial infarction and acute myocardial infarction caused by AAD.As to prognosis,the mortality of type A was higher than type B (30.7％ vs.3.4％,P ＜0.05).When treated with surgery (stent),the mortality was declined obviously (8.5％ vs.23.8％,P ＜ 0.05) while hospitalization.Confirmed time over 4 hours,shock caused by hypotension and (or) cardiac tamponade were independent risk factors for the prognosis of AAD.Conclusion The AAD patients' age of onset in our country is younger than foreigner'.High sensitivity of ultrasound can be a complementary diagnostic tool for critical AAD patients.Try to shorten the time of diagnosis and early operation can lower the mortality of AAD patients,type A patients might benefit from surgery.
