摘　　要：目的:探究相位对比电影-磁共振成像(PC-MRI)技术分析小脑扁桃体下疝(Chiari)畸形Ⅰ型患者手术前后脑脊液流体力学的变化及术后颅内感染的影响因素。方法:本研究选取本院2019年1月-2022年1月接诊的80例Chiari畸形I型患者展开研究;对所有患者头颈行MRI和PC-MRI检查,使用Q-flow软件进行脑脊液流体力学分析。对比Chiari畸形I型患者手术前后脑脊液流体力学指标;分析Chiari畸形Ⅰ型患者中术后颅内感染者和未发生颅内感染者的临床特征差异;多因素Logistic回归分析影响Chiari畸形Ⅰ型患者术后发生颅内感染的影响因素。结果:术后3个月,Chiari畸形I型患者中脑导水管平均流量(MF)、每搏输出量(SV)和反流分数(RF)均明显高于术前24 h,足向最大峰值流速(Vdmax)和头向最大峰值流速(Vumax)明显低于术前24 h(P<0.05);术后3个月,Chiari畸形I型患者脑桥腹侧MF和SV均明显高于术前24 h,RF、Vdmax和Vumax均明显低于术前24 h(P<0.05);术后3个月,Chiari畸形I型患者C3腹侧MF和SV均明显高于术前24 h,RF、Vdmax和Vumax均明显低于术前24 h(P<0.05);Chiari畸形Ⅰ型患者中术后发生颅内感染者有19例,未发生感染者有61例;多因素Logistic回归分析结果显示年龄较大、手术时间较长、抗生素未使用和术后脑脊漏液是Chiari畸形Ⅰ型患者术后发生颅内感染的危险因素(P<0.05)。结论:对于Chiari畸形Ⅰ型患者而言,对其行PC-MRI分析,可将其手术前后脑脊液流体力学进行检测,检测效果较优;Chiari畸形Ⅰ型患者术后发生颅内感染的危险因素包括年龄较大、手术时间较长、抗生素未使用和术后脑脊漏液。Objective:To explore the phase-contrast magnetic resonance image(PC-MRI)technology analysis the changes of cerebrospinal fluid hydrodynamics before and after surgery in patients with subtonsillar hernia(Chiari)malformation type I and the influencing factors of postoperative intracranial infection.Methods:In this study,80 patients with Chiari malformation type I who were admitted to our hospital from January 2019 to January 2022 were selected for study.MRI and PC-MRI examinations were performed on the head and neck of all patients,and cerebrospinal fluid hydrodynamics were analyzed using Q-flow software.The cerebrospinal fluid hydrodynamics indexes of patients with Chiari malformation type I were compared before and after surgery.The difference of clinical features between postoperative intracranial infection and non-intracranial infection in patients with Chiari malformation typeⅠwere analyzed.Multivariate Logistic regression analysis of the influencing factors of postoperative intracranial infection in patients with Chiari malformation type I.Results:3 months after surgery,the mean flux(MF),stroke volume(SV)and regurgitant fraction(RF)in the patients with Chiari malformation type I were significantly higher than those at 24 h before surgery,and the maximum peak velocity of foot(Vdmax)and maximum peak velocity of head(Vumax)were significantly lower than those at 24 h before surgery(P<0.05).3 months after surgery,the ventral ponsMF and SV in the patients with Chiari malformation type I were significantly higher than those at 24 h before surgery,and RF,Vdmax and Vumax were significantly lower than those at 24 h before surgery(P<0.05).3 months after surgery,ventral MF and SV of C3 and RF,Vdmax and Vumax in the patients with Chiari malformation type I were significantly higher than those at 24 h before surgery(P<0.05).Among the patients with Chiari malformation type I,there were 19 cases with intracranial infection after surgery,and 61 cases without infection.Multivariate Logistic regression analysis showed that ol
