背景资料：经皮椎体成形术（PVP）在一定程度上改善了背痛并纠正了脊柱错位，从而可能改善呼吸功能。目的：回顾性研究PVP术后呼吸功能的变化。材料和方法：2005年1月至6月，41例因骨质疏松导致的椎体压缩性骨折（37个胸椎[Th 6-Th 12]和50个腰椎[L1-L5]）接受PVP的患者（平均年龄72.0岁，范围59-86岁; 39例女性，2例男性）到我院进行随访咨询。在该随访咨询时，进行呼吸功能测试，包括用力肺活量百分比（FVC%）和1秒用力呼气量百分比（FEV1%）。我们采用Wilcoxon符号秩检验回顾性比较了这些值与PVP前的值。结果：术前FVC%为85.2±30.3%，术后平均10个月随访时FVC %为91.5±16.8%，差异有统计学意义（P<0.003）。FEV1%无显著差异。关于治疗节段的数量，即单椎体成形术与多椎体成形术，证实FVC%的改善无显著差异（P=0.1）。16例患者PVP前FVC%异常低（≤79%），其中6例患者（38%）术后改善至正常范围内。结论：PVP可改善术前降低的肺功能，但这种改善需要时间。
Background: Percutaneous vertebroplasty (PVP) improves back pain and corrects spinal misalignment to some extent, and thus may improve respiratory function. Purpose: To retrospectively investigate changes in respiratory function after PVP. Material and Methods: 41 patients (mean age 72.0 years, range 59–86 years; 39 women, two men) who had undergone PVP for vertebral compression fractures (37 thoracic vertebral bodies [Th6–Th12] and 50 lumbar vertebral bodies [L1–L5]) caused by osteoporosis visited our hospital for follow-up consultation between January and June 2005. At this follow-up consultation, respiratory function testing, including percent forced vital capacity (FVC%) and percent forced expiratory volume in 1 s (FEV1%), was performed. We retrospectively compared these values with those taken before PVP using a Wilcoxon signed-rank test. Results: FVC% was 85.2±30.3% before PVP and 91.5±16.8% at follow-up (mean 10 months after PVP), which represented a significant difference (P<0.003). No significant difference in FEV1% was detected. Regarding the number of treatment levels, that is, single vertebroplasty versus multiple vertebroplasty, no significant difference in improvement of FVC% was confirmed (P=0.1). FVC% was abnormally low (≤79%) before PVP in 16 patients and improved to within normal range postoperatively in six of these patients (38%). Conclusion: PVP improves preoperatively decreased lung function, but this improvement takes time.
