背景:急性B型主动脉夹层假腔未闭合或血栓形成已被发现可以预测结果。假腔部分血栓形成的预后意义尚未阐明。方法:对1996—2003年间纳入急性主动脉夹层国际注册研究且出院时存活的201例急性B型主动脉夹层患者进行了分析。根据当次住院期间的假腔状态(未闭合、部分血栓形成或完全血栓形成)对Kaplan-Meier死亡率曲线进行分层。
BACKGROUND: Acute B-aortic dissection false lumen closure or thrombosis has been found to predict outcome. The prognostic significance of partial thrombosis of the false lumen has not yet been elucidated. METHODS: Totally 201 acute B-type aortic dissections who were included in the International Registry of Acute Disorders of Aortae 1996 to 2003 and survived discharge were analyzed. Kaplan-Meier mortality curves were stratified based on the state of the false lumen during the hospital stay (unclosed, partial thrombosis or complete thrombosis).
