50例急性主动脉夹层患者的临床与影像探讨

目的：分析急性主动脉夹层（AD）的临床特点、诊断以及预后。方法：选择急诊科入院的50例AD病例，对临床表现、确诊方法及预后等进行回顾性分析。结果：引起AD的主要原因主高血压（58．0％），磁共振成像（MPI）的确诊率最高（93．8％），超声心动图（UCG）的确诊率（86．5％）与CT的确诊率（84．6％）相近。结论：AD的临床表现复杂，病情凶险，对怀疑为AD的患者给予UCG、CT、MRI等检查，早日确诊。对AD患者应加强随访，用UCG随访AD患者，有利于早期发现潜在的危及生命的并发症。

Acute dissection of aorta - a report of 50 cases

Objective To study the clinical features, diagnosis and prognosis of acute dissection of aorta (AD).Methods Clinical manifestations, diagnosis and prognosis of 50 cases of AD were retrospectively analyzed.Results The major reason for AD was hypertension (58.0 %). The diagnostic rate of MRI for AD was highest ( 93.8 % ), followed by ultrasonic cardiogram ( 86.5 % ) and CT ( 84.6 % ).Conclusion The clinical features of AD were complicated. The diagnosis of AD is based on the results of ultrasonic cardiogram, CT, or MRI. The follow up to the patients with AD by ultrasonic cardiogram is very important.
