A 81-year-old female was hospitalized with chest discomfort. Findings of CT scan revealed Stanford type A acute aortic dissection, but the dissecting lumen had already closed with thrombus. Aortogram showed no intimal tear, intimal flap or ulcer like projection. Under the diagnosis of "closing aortic dissection", conservative treatment was selected. The dissecting lumen was disappearing gradually, but she had a sudden chest pain on hospital day 4 and CT scan demonstrated an enlarged and enhanced dissecting lumen. She underwent an emergency operation and a hemiarch replacement was performed successfully. Her postoperative course was uneventful and she was discharged from the hospital in good health.
一名81岁女性因胸部不适入院。CT扫描结果显示为A型急性主动脉夹层，但夹层腔已被血栓闭塞。主动脉造影未显示内膜撕裂、内膜瓣或溃疡样突出。在诊断为“闭合性主动脉夹层”后，选择了保守治疗。夹层腔逐渐消失，但她在住院第4天突然出现胸痛，CT扫描显示夹层腔扩大且强化。她接受了急诊手术，成功进行了半弓置换。术后恢复顺利，她健康出院。
