Application of Cine PC-MRI Technology in Evaluating the Efficacy of Arnold Chiari Malformation Surgery
Objective To explore the application of Cine PC MRI technology in the evaluation of surgical efficacy for cerebellar tonsil hernia(Arnold Chiari)malformation.Methods 65 patients with Arnold Chiari malformation undergoing surgical treatment collected from multiple centers from August 2018 to September 2022.were selected as the research subjects.All patients were followed up for 6 months after surgery.The prognosis,quality of life,atlantodontoid distance(ADI)value,diameter of spinal cord cavity,posterior fossa slope length,transverse diameter of foramen magnum,length of posterior fossa height,and cerebrospinal fluid flow of patients before and 6 months after surgery,and investigate the complications during the follow-up period were compared.Results 6 months after surgery,the scores of chicago chiari outcome scale(CCOS)and health related quality of life(HRQoL)of the patient were higher than before surgery(P＜0.05);During the follow-up period,there were 3 patients who underwent reconstruction of the occipital cistern who experienced cerebrospinal fluid leakage from their wounds and were treated with lumbar cistern drainage.After 7 d,the wounds healed well.6 months after surgery,the value of atlantoodontoid distance(ADI)and spinal cord cavity diameter of patient were lower than before surgery;The length of the posterior fossa slope and the height diameter of the posterior fossa were longer than before surgery;The stroke output(SV)and mean flow rate(MF)at the level of pontomedullary cistern,the level of midbrain aqueduct,and the level of cervical disc were all higher than before surgery;The peak head flow velocity(Vumax)and foot peak flow velocity(Vdmax)were lower than before surgery(P＜0.05).Conclusion Surgical treatment for Arnold Chiari malformation patients could effectively improve prognosis and improve quality of life.However,attention should be paid to preventing cerebrospinal fluid leakage during occipital cistern reconstruction surgery,and Cine PC-MRI technology could provide an effective basis for evaluating the surgical treatment efficacy of Arnold Chiari malformation patients.
