Abstract:

objective To investigate the clinical effect and experience of radiofrequency ablation (RFA) on the treatment of hepatic hemangioma. Methods Clinical data of 100 patients with a total of 101 hepatic hemangiomas treated by RFA from Mar. 2013 to Oct. 2017 in General Hospital of Xinjiang Military Area Command were retrospectively analyzed. Pre-and-post-RFA maximum diameter of tumor and postoperative complications of hemorrhage, hematuria, renal dysfunction and others were statistically analyzed. Results Among 101 hepatic hemangiomas, 88 were completely ablated, with a complete ablation rate of 87.1%; hemangiomas with diameter ≤4 cm had a complete ablation rate of 92.1% (35/38) and with diameter >4 cm had a complete ablation rate of 84.1% (53/63). One month after RFA, average diameter of all hemangiomas was decreased from (4.2±1.8) (2~11) cm to (2.1±1.8) (0~6) cm, with statistically significant difference (P=0.03). Maximum diameter of a hemangioma with diameter of 11 cm was reduced by 54.4% after RFA. And 52% patients (52/100) had fever, with the highest body temperature of 37.5~38.5 ℃, which became normal after physical cooling without antibiotic treatment. Three to five days later, no fever occurred; no serious complications occurred. All patients had no serious postoperative complication. Conclusion RFA is a safe and effective way for treating hepatic hemangiomas, especially with more obvious effectiveness for small-size hepatic hemangiomas. But the individualized RFA should be adopted according to hepatic hemangiomas’ size, local relationship and distribution characteristics.
