Dural Tears and Cerebrospinal Fluid Leak in Osteotomy Surgery for Ankylosing Spondylitis: Incidence, Risk Factors
The total accidental dural tears rate in osteotomy surgery for AS is 33.6%. PSO presents a higher risk compared to SPO procedures. Factors such as the thickness of the posterior epidural space at the PSO segment, Anderson lesions, and dural ossification observed in CT scans serve as predictors for dural tears during PSO procedures. A comprehensive preoperative CT imaging assessment can provide valuable guidance regarding the potential occurrence of accidental dural tears and CSF leakage.
