Delayed intracranial hemorrhage is an unusual complication associated with the use of silastic dural substitute.
We present three patients with this complication. Two adult patients developed subdural and epidural hemorrhages 9 months and 10 years after posterior fossa surgery for Chiari malformations. The remaining patient, a 13-month-old child, is the youngest reported patient to develop an epidural hematoma 8 months after a craniosynostosis repair.
The hematomas were removed with the silastic dural substitute from all three patients, and the dural defect was repaired with autologous paracervical fascia.
Silastic dural grafts have an increased incidence of hemorrhage associated with their use. A slight increase in the prevalence of hemorrhagic complications with silastic dural substitute was observed in women. We report our radiographic and surgical findings, including an extensive review of the literature.
迟发性颅内出血是使用硅橡胶硬脑膜替代物相关的一种罕见并发症。
我们报告了3例出现该并发症的患者。2例成年患者在因Chiari畸形行后颅窝手术后9个月和10年分别发生硬膜下和硬膜外出血。其余1例患者为13个月大的儿童,是报道中最年幼的在颅骨缝早闭修复术后8个月发生硬膜外血肿的患者。
3例患者均将血肿与硅橡胶硬脑膜替代物一并清除,硬脑膜缺损用自体宫颈旁筋膜修复。
使用硅橡胶硬脑膜移植物时出血发生率增加。观察到女性使用硅橡胶硬脑膜替代物时出血并发症的发生率略有升高。我们报告了影像学及手术结果,包括对文献的广泛回顾。
