BACKGROUND Shunting to the cranial venous sinus represents a novel treatment strategy for hydrocephalus. To our knowledge, overdrainage as a complication after shunting to the cranial venous sinus has not previously been reported in the clinical literature. Here we report the case of a 50-year-old man who suffered from overdrainage after a ventriculosinus shunt insertion. CASE DESCRIPTION A 50-year-old man was admitted to our hospital with recurring fever and gait difficulty 4 months after a ventriculoperitoneal shunt (VPS) insertion for primary communicating hydrocephalus. Cerebrospinal fluid cultures were positive. The previous VPS was removed, and after successful antibiotic treatment evidenced by repeated negative cerebrospinal fluid (CSF) cultures, we performed a ventriculosinus shunt operation. A postoperative computed tomography scan of the head showed an excessively contracted ventricular system, subdural hemorrhage, and effusion, indicating the occurrence of overdrainage. CONCLUSIONS Ventriculosinus shunt surgery is a feasible and reliable option for the treatment of hydrocephalus, especially for cases of failed VPS. However, there remains a risk of overdrainage occurring postsurgery, and this should be taken into consideration in clinical practice.

脑室分流继发的过度引流。

背景技术对颅静脉窦的分流代表了脑积水的一种新型治疗策略。据我们所知，在临床文献中尚未报道过分流至颅静脉窦后的并发症。在这里，我们报道了一个50岁的男子，他在插入心室分流术后过度引流。病例描述一名50岁的男子因插入室腹腔分流（VPS）进行原发性沟通性脑积水，在4个月后因反复出现的发烧和步态困难而入院。脑脊液培养阳性。去除了先前的VPS，在通过反复的阴性脑脊液（CSF）培养证明成功的抗生素治疗后，我们进行了脑室分流手术。头部的术后计算机断层扫描显示脑室系统过度收缩，硬膜下出血和积液，表明发生了过度引流。结论脑室静脉分流术是治疗脑积水的可行且可靠的选择，尤其是对于VPS失败的病例。但是，术后仍有引流过度的风险，在临床实践中应考虑到这一点。
