治疗动脉瘤样骨囊肿(ABC)的传统方法是手术,但切除伴或不伴骨移植术后的复发率达18％～59％。有报道用石炭酸,液氮,骨水泥,明胶海绵栓塞等方法来减少复发。作者对10例ABC病人进行CT引导下经皮囊腔内注射Ethibloc。男性7例,女性3例,年龄4～16岁(平均11.8岁)。其中肱骨5例,胫骨2例,股骨2例,骨盆1例。4例是行刮除和植骨术后复发,1例曾应用自体骨髓抽吸物注射治疗无效,5 The traditional method for the treatment of aneurysmal bone cysts (ABC) is surgery, but the recurrence rate after resection with or without bone grafts ranges from 18% to 59%. It has been reported to reduce recurrence with methods such as carbolic acid, liquid nitrogen, bone cement, and gelatin sponge embolization. The authors performed CT-guided percutaneous injection of Ethibloc into 10 patients with ABC. There were 7 males and 3 females, aged 4-16 years (average 11.8 years). Among them, there were 5 cases of tibia, 2 cases of tibia, 2 cases of femur, and 1 case of pelvis. 4 patients had recurrence after curettage and bone grafting, and 1 patient had ineffective treatment with autologous bone marrow aspirate injection. 5
