Chemotherapy for ALHs
Bleomycin (1.5 million units/bottle) (Tianjin Tai-He Pharmaceutical) was dissolved in 5 mL of normal saline solution. A 23-gauge needle was used to inject the bleomycin into the ALHs until the surface of the ALHs became slightly pale. Multipoint injections were advised. Finally, epinephrine-soaked cotton balls were used to apply pressure to the ALHs for 5 min. The maximum dose per patient was 24 mg.
