客观化
本研究的目的是描述气管成形术前后动态CT在患者中的作用，气管成形术是一种治疗严重症状性气管支气管软化症的新手术方法。
结论
5例患者在我们机构接受气管成形术前后进行了动态多层螺旋CT扫描。术前，所有患者在支气管镜检查中均有气管、支气管壁软化的征象(或=50%)，其中4例(80%)在动态用力呼气CT扫描中显示软化。所有5例术后CT均显示呼气时呼吸道塌陷程度减轻，吸气时气管形状改变，与手术相关的后壁增厚。我们的初步结果表明，CT在气管成形术治疗的气管支气管软化症患者的术前和术后评估中具有潜在的重要作用。
OBJECTIVE
The objective of this study was to describe the role of pre- and postoperative dynamic CT in patients undergoing tracheoplasty, a novel surgical method for treatment of severely symptomatic tracheobronchomalacia.
CONCLUSION
Five patients were referred for dynamic MDCT before and after undergoing tracheoplasty at our institution. Preoperatively, all patients showed signs of tracheobronchomalacia (> or = 50% airway collapse) on bronchoscopy, and four (80%) of these five patients showed evidence of malacia on dynamic forceful expiratory CT scans. In all five cases, postoperative CT showed a reduction in the degree of airway collapse during expiration, changes in shape of the trachea during inspiration, and posterior wall thickening related to the procedure. Our preliminary results suggest a potentially important role for CT in the pre- and postoperative assessments of patients with tracheobronchomalacia referred for tracheoplasty.
