Combined Preoperative Embolization and Surgical Treatment of a Giant Aneurysmal Bone Cyst in the Lumbar Spine: A Case Study

Özet

An aneurysmal bone cyst (ABC) is a vascular locally proliferative, non-neoplastic, benign lesion observed in children and youngadults. 75% of ABCs occur before the age of twenty. The cyst frequently develops in the long bones and comprises 1.4% of primarybone tumors. Spinal ABC is rare and is typically observed in the thoracic and cervical regions. In the spinal region, the posteriorelements of a single vertebra are usually involved. The lamina, pedicle, facet joints are more commonly affected. The lesion may alsoexpand toward the corpus. We present a case involving successful total excision of a lumbar spinal giant ABC by combining surgerywith preoperative coil embolization. Preoperative arterial embolization contributes to decreased morbidity and mortality rates byreducing the duration of surgery and occurrence of intraoperative hemorrhage.
