Application of 3D reconstruction technology using 3D Slicer software in pre-operative assessment of patients with primary hemifacial spasm undergoing microvascular decompression
Objective To investigate the application value of 3D reconstruction technology using 3D Slicer software in the preoperative evaluation of patients with hemifacial spasm(HFS)undergoing microvascular decompression(MVD).Methods The clinical data of 200 patients with HFS who underwent MVD from June 2022 to December 2023 were retrospectively analyzed.All patients underwent 3D-FIESTA and 3D-TOF MRA preoperatively,and the 3D Slicer software was used for 3D reconstruction to guide MVD.The intraoperative finding was served as the gold standard.Results Except for one negative patient,responsible vessels were found intraoperatively in 199 patients,including anterior inferior cerebellar artery(AICA)in 111 patients,posterior inferior cerebellar artery in 52 patients,vertebral artery in 29 patients,and AICA combined with VA in 7 patients.The consistency between 3D-FIESTA and 3D-TOF MRA examination and intraoperative findings was generally(κ value=0.326),the sensitivity,specificity,and accuracy were 83.90%,100.00%,and 91.00%,respectively.The consistency between 3D reconstruction technology and intraoperative findings was good(κ value=0.651),the sensitivity,specificity,and accuracy were 99.00%,100.00%,and 100.00%,respectively.The prediction efficacy of 3D reconstruction technology on the responsible vessels was significantly better than that of 3D-FIESTA and 3D-TOF MRA examination(P<0.001).After follow-up for 6～24 months,with a median time of 12 months,complete symptom relief was achieved in 142 patients(71.00%),partial relief in 51(25.50%),and no change in 7(3.50%).Conclusion For patients with HFS,MVD guided by 3D reconstruction technology using 3D Slicer software based on the data of 3D-FIESTA and 3D-TOF MRA examination can reduce the risk of missing the responsible vessels,and improve the success rate of surgery.
