The treatment of cavernous hemangioma of liver by transcatheter hepatic arterial embolization

Objective To investigate the therapeutic effects of hepatic arterial embolization for cavernous hemangiomas of 1iver(CHL). Methods 28 patients with cavernous hemangiomas of 1iver were treated with pingyangmycin-lipiodol emulsion combined with gelatin spongy particles by transcatheter hepatic arteria1 embolization. All cases were followed up for12～24 months after therapy. Results During the period of follow-up,the cavernous hemangiomas were shrunk to varying degrees and symptoms subsided in al1 cases after 1 to 3 procedures of embolization. The size of tumors partially responsed (by more than 50% )in 19 (67.9%,19/28) and minimal responsed (by more than 25% but less than 50%) in 7 (25%,7/28) of the total. No significant complications occurred in this series. Conclusion Combined embolization of pingyangmycin-lipiodol emulsion with gelatin spongy particles is an optimal, safe and effective treatment for CHL.
