Abstract: Objective This study was conducted to evaluate blood supply and hepatic arterial embolization (HAE) efficacy by enhanced computed tomography (CT) in patients with hepatic hemangioma (HH). Methods 127 consecutive patients with HH were encountered in our hospital between December 2017 and January 2021, and all patients underwent CT plain and enhanced scan to measure arterial phase enhancement ratio and evaluate blood supply of HH. All patients were treated with HAE, followed-up for 3 years, and reduction rate of tumor size and arterial phase enhancement rate of HH were compared. Results Of 127 patients with HH, enhanced CT scan found rich blood supply lesions in 54 cases and poor blood supply lesions in 73 cases; of 54 lesions with rich blood supply, uniform enhancement at arterial stage in 18 cases, uneven enhancement in 25 cases, continuously enhanced at venous and delayed stage, and not enhanced at three-stages in 11 cases; enhancement rate at arterial stage in HH lesions with rich blood supply was(43.1±13.6)%, much higher than [(16.5±3.7)%, P＜0.05] in lesions with poor blood supply, and percentage of greater than 10 cm lesions was 9.3%, much lower than 64.4%(P＜0.05) in lesions with poor blood supply; by two and three years of follow-up, reduction rates of tumors with rich blood supply were(32.6±7.1)% and (53.9±10.2)%, and reduction rates of arterial stage enhancement were (21.8±2.4)% and (27.5±3.1)%, all significantly higher than [(21.5±4.9)% and (34.7±6.9)%, and (14.2±2.5)% and (19.6±2.7)%, P＜0.05] in lesions with poor blood supply. Conclusion Efficacy of HAE in dealing with HH with rich blood supply is better than those with poor blood supply, and evaluation of blood supply of HH by CT enhanced scan before operation might help make choice of measures and warrants further investigation.
