Abstract:
Objective To investigate the value of real-time virtual navigation system (RVS) combined with CEUS in guiding radiofrequency ablation (RFA) therapy of neonatal or recurrent lesions of hepatocellular carcinoma (HCC).Methods Totally 111 patients with neonatal or recurrent lesions of HCC after RFA therapy were enrolled.Seventy-eight patients with 86 lesions (77 neonatal lesions and 9 recurrent lesions) underwent RFA guided by RVS combined with CEUS (RVS combined with CEUS group),and 33 patients with 38 lesions (26 neonatal lesions and 12 recurrent lesions) underwent RFA guided by CEUS alone (control group).The precise localization,inactivation rate and local recurrence rate between the two groups were compared.Results Eighty-four lesions (84/86,97.67％) in RVS combined with CEUS group and 25 lesions (25/38,65.79％) in control group were clearly showed and localized (P＜0.001).One month after RFA therapy,the tumor inactivation rate in RVS combined with CEUS group and control group was 95.35 ％ (82/86) and 76.31％ (29/38),respectively (P=0.003).The local recurrence rate in RVS combined with CEUS group was 8.14％ (7/86),while was 36.84％ (14/38) in control group (x2 =15.434,P＜0.001).Conclusion RVS combined with CEUS guidance can improve the accurate position rate and early inactivation rate of RFA therapy for neonatal or recurrent lesions of HCC.
