目的 评价微创椎弓根钉内固定技术治疗胸腰椎爆裂骨折的中期临床疗效。 方法 2002年9月－2007年9月，采用微创椎弓根钉内固定技术治疗胸腰椎爆裂骨折30例。其中男16例，女14例;年龄18～65岁，平均39.8岁。骨折节段:胸11者3例， 胸12者13例， 腰1者12例， 腰者22例。所有骨折按AO分型，均为A3型。受伤至手术时间6 h～6 d，平均45 h。分析术后影像学指标、疼痛评分及功能障碍指数。 结果 患者均获随访，随访时间3～9年，平均5.2年。术后各时间点伤椎前缘高度及后凸Cobb角均较术前明显恢复（P＜0.01）。术后伤椎高度随随访时间延长逐渐下降，后凸Cobb角逐渐增大。取出内固定物后、术后2年、末次随访时动力位X线片上骨折椎体前后相对滑移距离分别为（1.9 ± 0.3）、（2.1 ± 0.2）、（2.1 ± 0.3）mm，两两比较差异无统计学意义（P＞0.05）。术后1、2年及末次随访时疼痛视觉模拟评分分别为（2.5 ± 1.2）、（2.5 ± 1.1）、（2.4 ± 1.3）分，两两比较差异无统计学意义（P＞0.05）。末次随访时Denis腰痛分级：P1级13例，P2级12例，P3级5例。功能障碍指数为（11.4 ± 3.1）分，获优23例、良5例、可2例。 结论 单纯微创椎弓根钉内固定技术治疗胸腰椎爆裂骨折中期临床效果满意，脊柱稳定性良好。Objective To mid-term efficacy of the technique of minimally invasive pedicle screw fixation on thoracolumbar burst fracture. Methods From September 2002 to September 2007, 30 patients were treated with minimally invasive pedicle screw fixation for thoracolumbar fracture. There were 16 males and 14 females with the mean age of 39.8 years (range,18-65 years). The injured level of was T11 in 3 cases, T12 in 13 cases, L1 in 12 cases, and L2 in 2 cases. The type of thoracolumbar fractures of all the patients was A3 according to AO classification. The during from injury to operation was 6 hours to 6 days with an average of 45 hours. The index of image and pain and disability index were evaluated after operation. Results All patients were followed up for 3 to 9 years with the mean of 5.2 years. Their average sliding distance after operation for removing internal fixation was (1.9 ± 0.3), and (2.1 ± 0.2) mm 2 years after the operation and (2.1 ± 0.3) mm at the latest follow-up. There was no significant difference (P＞0.05). Their average score was (2.51 ± 1.2) 1 year after the operation, was (2.42 ± 1.1) 2 year after the operation, and was (2.36 ± 1.3) at the latest follow-up (P＞0.05). According to Denis score system to evaluate index of lumbago, there was P1 in 13 cases, P2 in 12 cases, and P3 in 5 cases. The score of Oswestry Disability Index (ODI) was 11.4 ± 3.1 at the latest follow-up. Twenty-one cases gotexcellent therapeutic result, five cases got good and two were moderate. Conclusions Minimally invasive pedicle screw fixation for the treatment of thoracolumbar burst fracture provide satisfactory clinical results. The vertebral body and adjacent vertebral body have a good stability.

Objective To explore the clinical effect of ventricular septal defect repair and lung allograft (simply as "heart repair and lung transplant") in the treatment of ventricular septal defect complicated with severe pulmonary hypertension. Methods A 21-year-old female patient with ventricular septal defect and severe pulmonary hypertension was treated with cardiopulmonary bypass (CPB) under general anesthesia, and then right lung transplantation was performed, and then left lung transplantation was performed after changing body position. Results The operation was conducted successively. The intraoperative CPB support time was 90 minutes, and the blood loss was 2000 mL. Extracorporeal membrane oxygenation was removed on the second day after operation, the ventilator was evacuated on the third day, and the patient recovered and discharged on the 38th day. Postoperative echocardiography showed significant improvement in pulmonary artery pressure. Conclusion For patients with simple congenital heart disease complicated with severe pulmonary hypertension, "heart repair and lung transplant" can improve their quality of life.
