  • Investigation of Three-Step Radiofrequency Ablation in Treatment for Giant Hepatic Hemangioma

    ObjectiveTo investigate efficacy and safety of three-step radiofrequency ablation (RFA) in treatment for giant hepatic hemangioma (GHH,diameter ≥5 cm) with symptoms. MethodsThe patients with GHH met the inclusion criteria were collected.The main steps were as follows:The first step was to destroy the main arteries of the tumor to block the blood.The second step was to withdraw the blood of the tumor to shrink the tumor.The third step was to damage the shrunk tumor by RFA. ResultsThere were 13 patients with GHH met the inclusion criteria.The median preoperative diameter was 8.0 cm.The median volume of withdrawing blood was 78 mL.The median diameter after withdrawing blood was 5.3 cm.The diameters between after and before withdrawing blood had a significant difference (P<0.01).The time for damaging tumor blood supply was (4.4±1.0) min.The median frequency of tumor RFA was 4 times.The median time of tumor RFA was 16 min.The median time of total operation was 20 min.There were 3 cases of tumor residual after RFA,10 cases were met full damage,and the damage rate was 85.9%-100% with an average of 97.0%.The hospital stay after RFA was (3.9±1.2) d.One case was remission after conservative treatment because of complication. ConclusionThe preliminary results of limited cases in this study show that three-step RFA for GHH is effective and safe,but it needs to be researched for large samples data.
