A series of 7 cases of aneurysmal bone cysts (ABC), all but 1 located in the pelvic bones, which were treated by transcatheter embolization is presented. Five embolizations were performed for primary treatment, while in 2 patients they were performed preoperatively. In all patients a definite histological diagnosis was established by open biopsy, and plain radiographs as well as computerized tomography (CT) were applied for evaluation of the results. The embolizing materials were tissue adhesive for permanent, and Gelfoam for preoperative vessel occlusions. Of 5 lesions treated for the purpose of definitive embolization, 3 (all located in the superior pubic ramus) showed complete ossification; in one, partial remineralization and progression occurred. In a further patient with a secondary ABC, partial reconstitution was recorded. Both preoperative embolizations resulted in successful en bloc resection with minimal blood loss. Transcatheter embolization is the treatment of choice for the highly vascular ABC in unfavorable anatomical locations.
本文报告了7例动脉瘤样骨囊肿（ABC），除1例位于骨盆外，其余均位于骨盆骨，均采用经导管栓塞治疗。5例栓塞用于初始治疗，2例患者在术前进行栓塞。所有患者均通过开放活检确立明确的组织学诊断，并应用X线平片及计算机断层扫描（CT）评估结果。栓塞材料中，永久性栓塞用组织粘合剂，术前血管闭塞用明胶海绵。在5例接受确定性栓塞治疗的病变中，3例（均位于耻骨上支）显示完全骨化；1例出现部分再矿化及进展。另1例继发性ABC患者记录到部分修复。2例术前栓塞均成功实现整块切除，失血极少。对于解剖位置不佳的高血运ABC，经导管栓塞是首选治疗方法。
