Abstract: Objective The aim of this study was to investigate contrast-enhanced ultrasound (CEUS) in the diagnosis of hepatic hemangioma (HH and in evaluation of efficacy after transcatheter arterial embolization (TAE). Methods 86 patients with HH were encountered in our hospital between January 2021 and January 2024, and all underwent routine ultrasonography (US) and CEUS. TAE was performed in all patients with HH, and efficacy was evaluated three months after. Results Diameter of HH in our series was 5-10cm, with average of (7.4±1.1)cm; routine US found HH lesion regular in 65 cases (75.6%), clean margins in75 cases (87.2%),homogeneous echo in 67 cases (77.9%),high echo in 9 cases (10.5%) and rich blood supply in 19 cases (22.1%);CEUS demonstrated lesions with arterial phase high enhancement in 38 cases (44.2%), with overall enhancement in 33 cases (38.4%) and with centripetal enhancement in 15 cases (17.4%), with portal phase centrifugal enhancement in 4 cases (4.7%), with continuous high enhancement in 46 cases (53.5%) and with equal enhancement in 36 cases (41.9%), and with delayed phase high enhancement in 3 cases (3.5%), equal enhancement in 37 cases (43.0%) and with low enhancement in 46 cases (53.5%); three months after TAE, complete and partial remission rate was found in 73.7%% in 38 patients with HH lesion of overall enhancement, much higher than 45.8%(P<0.05) in 48 patients with lesions of centripetal /centrifugal enhancement. Conclusion TAE is efficacious in treatment of patients with HH, and those with CEUS overall enhancement might be even more satisfactory.
