Abstract

Purpose This study aims to review the results of sclerotherapy using Surgiflo in addition to alcohol in primary aneurysmal bone cysts (ABC). Methods A total of 16 consecutive patients with histologically confirmed diagnosis of primary ABC were treated by percutaneous Surgiflo and alcohol injection at our institution. Clinical follow-up included the assessment of pain, swelling, limping and functional impairment. Radiological parameters included tumour volume, physis-cyst distance, thickness of cyst cortex, and presence of intracystic septations. Mean follow-up was 35,6 months (24–71 months). Treatment was considered successful when the cyst volume decreased by a minimum of 10%, the bone cortex became thicker, and the distance to physis increased. Results Mean age at presentation was 9.5 years (5.16–13.84 years). All ABC’s were primary and all patients underwent a single Surgiflo and alcohol session except for two (12.5%) who required a second session. All patients had a good clinical result at final follow-up. Satisfactory cyst healing was achieved in 11 cases according to radiological parameters. Tumour volume decreased from a mean of 122 cm3 (111 to 133) before injection to 86 cm3 (76 to 96) at last follow-up (p < 0.01). Physis-cyst distance increased from a mean of 1 cm (0.1 to 2) to 2.1 cm (0.5 to 4) at last follow-up (p < 0.01). Cortical thickness improved from 1 mm (0.5 to 1.5) to 2 mm (1 to 3.5) at last follow-up (p < 0.01). There were no treatment related complications. Surgery was performed in one patient having a C3 vertebra ABC after developing quadriparesis due to tumour progression. Conclusion Sclerotherapy using Surgiflo and alcohol may be used as an efficient, safe and minimally invasive alternative for the treatment of primary ABCs.
