| 【摘要】 目的：评估强直性脊柱炎（ankylosing spondylitis，AS）后凸畸形经椎弓根椎体截骨（pedicle subtraction osteotomy，PSO）术前和术后患者肺功能的变化，并探讨影响术后肺功能改变的相关因素。方法：收集2009年6月～2011年6月收治的32例AS后凸畸形行PSO脊柱矫形术患者的资料。男性27例，女性5例；年龄36.4±7.8岁（22～52岁）。随访时间为2年，随访的内容包括：肺功能检查，静息状态下憋气时间（breath-holding time，BHT），自然站立位脊柱全长X线片上测量后凸Cobb角（T1～S1）。比较术后及术后2年随访时肺功能较术前是否有变化，并分析肺功能变化与性别、年龄、病程和脊柱矢状面参数之间的关系。结果：29例（男性25例，女性4例）患者完成了随访，失访率为9.3%。手术前BHT为32.5±10.1s，2年随访时增加至43.1±8.6s。术前肺功能检查结果：2例正常，17例轻度限制性通气功能障碍，9例中度限制性通气功能障碍，1例重度限制性通气功能障碍，无阻塞性通气功能障碍及混合性通气功能障碍；2年随访时肺功能检查结果：19例正常，10例轻度限制性通气功能障碍。肺活量预测百分比（PredVC%）术前为68.4%±9.5%，2年随访时为79.4%±6.1%；用力肺活量预测百分比值（PredFVC%）术前为75.5%±6.4%，2年随访时为81.0%±6.9%。后凸Cobb角术前为63.0°±20.3°，术后为15.3°±10.3°，术后2年随访时为17.1°±10.9°。且PredVC%和PredFVC%的改善与AS后凸Cobb角的矫正成正相关性（r=0.6328和0.8612，P＜0.01）。结论：AS后凸畸形PSO术后2年肺功能较术前改善明显，且肺功能的改善与T1～S1后凸Cobb角的矫正呈正相关性。 |

| 【Abstract】 Objectives: To observe postoperative change in pulmonary function in patients with ankylosing spondylitis(AS) kyphosis after pedicle subtraction osteotomy(PSO), and investigate the related factors of pulmonary function changes after operation. Methods: From June 2009 to June 2011, a total of 32(27 males and 5 females) patients with AS kyphosis were eligibly involved. 29(25 males and 4 females) patients with a mean age of 36.4±7.8 years(range, 22-52 years) completed the follow-up and 3(2 males and 1 female) patients lost. Pulmonary function tests, breath-holding time and full-length spine X-ray films in natural standing position were followed postoperatively. The study explored whether there was a change in lung function postoperatively, the relationship of the possible existence of lung function changes with gender, age, course of the disease and the spinal sagittal parameters was investigated. Results: Cobb T1-S1 significantly decreased from 63.0°±20.3° preoperatively to 15.3°±10.3° postoperatively and 17.1°±10.9° at 2-year follow-up. The breath-holding time(BHT) before surgery was 32.5±10.1s, while the postoperative BHT increased to 43.1±8.6s(P<0.05). Two AS patients had normal pulmonary function test before operation, while there were 19 patients at 2-year follow-up. The clinical improvement rate was 85.2%(23/27). The percentage predicted vital capacity(PredVC%) increased from (68.4±9.5)% to (79.4±6.1)% at 2-year follow-up(P<0.05). The percentage predicted forced vital capacity(PredFVC%) before PSO was (75.5±6.4)% and (81.0±6.9)% at 2-year follow-up(P<0.05). The improved PredVC% and PredFVC% had a positive correlation with the correction of Cobb T1-S1(r=0.6328 and 0.8612, P＜0.01, respectively). Conclusions: The postoperative pulmonary function including pulmonary volume and ventilatory function in AS patients with kyphosis is significantly improved at 2-year follow-up. And the improved pulmonary function has a positive correlation with the kyphosis correction. |
