Abstract: Objective To investigate the impact of blood supply on efficacy of hepatic artery embolization in treatment of patients with hepatic hemangioma. Methods 100 patients with hepatic hemangioma were recruited in our hospital between January 2013 and August 2017,and the patients were divided into group A（n=37） with rich blood supply,group B （n=34） with moderate blood supply and group C （n=29） with poor blood supply. All the patients with hepatic hemangioma received transcatheter hepatic arterial embolization with pingyangmycin and iodized oil. All the patients were followed-up for 12 months. Results At the end of six and twelve months,the efficient rate in group A were 64.9% and 81.1%,significantly higher than 61.8% and 67.7% in group B or 3.5% and 10.3% in group C （P<0.05）;the volumes of pingyangmycin and iodized oil in group A,group B and group C were （11.4±2.6） ml,（9.7±1.9） ml and （4.3±1.0） ml,significantly different among the three groups （P<0.05）;at the end of twelve month,the diameter of focus in group C was （6.6±0.7） mm,much larger than （2.8±0.2） mm in group A or （3.2±0.3） mm in group B（P<0.05）;the short-term post-operational complications such as liver injury in group A was 18.9%,significantly higher than 8.8% in group B or 3.4% in group C（P<0.05）. Conclusion The therapeutic effect of hepatic artery embolization for different blood supply types of hepatic aneurysms should be obviously different. In clinical practice,it should pay attention to choosing reasonable therapeutic methods according to the blood supply tipu to improve the therapeutic effect and safety.
