Continuous variables are expressed by median ± standard deviation.

Hb, hemoglobin; TBil, total bilirubin; ALT, alanine aminotransferase; AST, aspartate transaminase; BUN, blood urea nitrogen.

PT, prothrombin time; APTT, activated partial thromboplastin time.

For the patients with multiple hepatic hemangiomas, the hepatic hemangiomas not managed were not included statistical range.
