背景Stanford B型夹层患者在急性期通过药物降压治疗成功，但由于夹层主动脉扩大，大量患者在慢性期出现手术风险。本研究的目的是通过研究在急性期药物降压治疗成功的患者主动脉夹层的慢性期扩大，来确定急性B型夹层手术治疗的指征。方法与结果对41例急性期接受医学治疗的B型夹层患者进行单因素和多因素分析，以确定慢性期夹层主动脉扩大（大于或等于60mm）的主要预测因素。每隔4 ~ 14个月行ct检查，观察最大主动脉直径是否增大。慢性期主动脉扩张的主要预测因子是急性期最大主动脉直径大于或等于40mm
Background In patients with Stanford type B dissection who have been treated successfully with medical hypotensive therapy during the acute phase, a large number have incurred the risk of surgery during their chronic phases because of enlargement of the dissected aorta. The purpose of this study was to determine the indications for surgical treatment of acute type B dissection by studying chronic-phase enlargements of aortic dissections in patients treated successfully with medical hypotensive therapy during the acute phase.Methods and Results In 41 patients with type B dissection who had been treated medically during the acute phase, univariate and multivariate factor analyses were made to determine the predominant predictors for chronic-phase enlargement (greater than or equal to 60 mm) of the dissected aorta. Computed tomography was performed every 4 to 14 months to observe whether there was enlargement of the maximum aortic diameter. The predominant predictors for aortic enlargement in the chronic phase were the existence of a maximum aortic diameter of greater than or equal to 40 mm during the acute phase (P
