36例主动脉夹层早期诊断及误诊分析

目的探讨主动脉夹层的临床表现、早期诊断及误诊情况。方法分析36例主动脉夹层临床表现，体检、实验室检查、心电图检查、X线片、超声心动图、CT、MPd等检查结果。结果36例主动脉夹层的临床表现各异，典型撕裂样疼痛22例（61．1％），部分患者以并发症为首发症状，影像学检查能确定诊断。主动脉夹层的临床表现复杂，初诊误诊率50％。结论主动脉夹层临床表现复杂，易误诊，应引起临床医师的高度重视。

The Analysis of Early Diagnosis and Misdiagnosis of Aortic Dissection

Objective To detect the condition of early diagnosis and misdiagnosis of aortic dissec- tion(AD)through invest the AD patients'clinical situation.Methods The symptoms,physical signs, and the results of laboratory test,electrocardiogram,x-ray film,CT,MRI of 36 patients with AD were ana- lyzed.Results The symptoms and physical signs of AD were different.22 patients have typical tearing pain (61.1%).Some patients may present a myriad of symptoms initially secondary to the involvement of the or- gan systems.The finial diagnose can be made through CT or MRI.Its misdiagnosis rate was 50%.The main causes of misdiagnosis of AD include the patients'multiple clinical situations and lacking a high clinical in- dex of suspicion in the clinics.Conclusion The symptoms and physical signs of AD are complex.This dis- ease might be misdiagnosed because of less knowledge about AD in clinical physicians,suggesting that more attention should be paid to AD.
