Delayed sagittal sinus tear: a complication of spring cranioplasty for sagittal craniosynostosis.

Spring cranioplasty is now a well-established surgical technique in the treatment of sagittal craniosynostosis. It is widely regarded as a less invasive modality compared with operations such as cranial vault remodeling. Indeed, very few complications have been described in the literature in association with spring cranioplasty. We present a case of delayed sagittal sinus tear with hemorrhage following spring cranioplasty in a 4-month-old patient with sagittal craniosynostosis. Likely causes of the injury are discussed highlighting sagittal sinus injury as a potential risk of spring cranioplasty.
