Common complications following cranioplasty (CP) include infections, seizures, bone flap resorption, and intra-cranial hemorrhages. Epidural fluid collections (EFCs), often seen in the immediate post-operative scan as hypo-dense accumulations below the bone flap, have been very infrequently discussed in the literature as in the majority of the cases, they are small, get resorbed spontaneously, and usually do not cause neurological deficits.
To document our experience with EFCs that needed re-operation and analyze their clinical and radiological findings.
We describe a series of six cases of symptomatic EFCs following CP that necessitated re-operation in a series of 89 cases over 7 years.
EFCs following CP have a different pathogenetic mechanism compared to post-operative epidural hemorrhages. Meticulous surgical techniques can reduce their incidence. Symptomatic EFCs can be evacuated by either re-opening the flap or placing burr holes in the replaced bone. EFCs may become symptomatic even a few days after CP.
颅骨修补术后常见的并发症包括感染、癫痫发作、骨瓣吸收和颅内出血。硬膜外积液（EFC）在术后即刻的扫描中常表现为骨瓣下方的低密积聚，在文献中很少被讨论，因为在大多数情况下，它们较小，会自发吸收，通常不会导致神经功能缺损。
记录我们在需要再次手术的 EFC 方面的经验，并分析其临床和影像学表现。
我们描述了 7 年内对 89 例颅骨修补术后发生的 6 例症状性 EFC 再次手术的病例系列。
颅骨修补术后的 EFC 与术后硬膜外出血的发病机制不同。精细的手术技术可以降低其发生率。症状性 EFC 可以通过重新打开骨瓣或在置换骨上钻骨孔来清除。EFC 甚至在颅骨修补术后数天也可能出现症状。
