目的：探究选择性脊神经后根切断术（ＳＰＲ）治疗脑瘫术后并发症的原因与防治办法。方法：对１０３例ＳＰＲ术后进行近期疗效观察与远期随访。结果：在术后近期并发症中主要有肠绞痛、排尿功能障碍、局限性感觉异常或缺失及脑脊液漏。远期并发症为髋关节脱位、脊柱畸形、肌无力。结论：ＳＰＲ术后近期并发症中多为暂时性的，多在术后３周内自愈。而远期并发症则影响治疗效果，正确的处理与预防术后并发症可提高手术疗效 Objective: To explore the causes and prevention and treatment of postoperative complications of selective posterior rhizotomy (SPR). Methods: Short-term efficacy and long-term follow-up were observed in 103 patients after SPR. Results: There were colic, micturition dysfunction, limited sensory abnormalities or absences and cerebrospinal fluid leakage in the near postoperative complications. Long-term complications of dislocation of the hip, spinal deformity, muscle weakness. Conclusions: Most of the recent complications after SPR are mostly temporary, and are mostly self-healing within 3 weeks after operation. The long-term complications affect the treatment effect, the correct treatment and prevention of postoperative complications can improve the surgical efficacy
