Abstract
BACKGROUND: There is a lack of research to determine the efficacy of cervical perivascular sympathectomy (CPVS) in children with cerebral palsy (CP). OBJECTIVE: This study aimed to evaluate the efficacy of CPVS in children with CP and analyze the associated influential factors. METHODS: Using the method of retrospective cohort studies, children who underwent CPVS were included in the CPVS group, whereas those who underwent selective posterior rhizotomy (SPR) were included in the SPR group. The Communication Function Classification System (CFCS) and Teacher Drooling Scale (TDS) were used to evaluate the communication function and salivation in the two groups before and 12 months after surgery and compare the surgical efficiency between the two groups, and the factors affecting the efficacy were screened by binary logistic regression. RESULTS: The study included 406 patients, 202 in the CPVS group and 204 in the SPR group. No significant differences were observed in the baseline characteristics (p > 0.05). The surgical efficacy of the CPVS group (47.01%) was significantly higher than that in the SPR group (9.81%) (χ(2) = 71.08, p < 0.001). Binary logic regression analysis showed that preterm birth and Gross Motor Function Classification System (GMFCS) grade were influencing factors of surgical efficacy. Eighteen patients developed postoperative complications. CONCLUSION: CPVS is a safe and effective surgery for cerebral palsy. Preterm birth and GMFCS grade are independent factors affecting the efficacy of surgery.
