Cerebral hydrodynamics complications in shunted patients are due to the malfunction of the system. The objective of this retrospective, single-center, single-arm cohort study is to confirm the safety and performance of Sphera® Duo when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cysts.
Data were generated by reviewing 112 adult patient's charts, who were submitted to a ventriculoperitoneal shunt surgery and followed for one year after surgery.
The results show us that 76% of patients had their neurological symptoms improved and that the reoperation rate was 15% in the first year following surgery.
Sphera Duo® shunt system is an applicable shunt option in routine neurosurgical management of hydrocephalus by several causes. It has presented good results while mitigating effects of overdrainage. Overdrainage is especially important in adults with non-hypertensive hydrocephalus and can cause functional shunt failure, which causes subnormal ICP (particularly in the upright position) and is associated with characteristic neurological symptoms, such as postural headache and nausea.
Sphera Duo® shunt system is safe when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cyst.
分流患者的脑流体动力学并发症是由于系统故障所致。这项回顾性、单中心、单臂队列研究的目的是确认Sphera® Duo在患有脑积水、假性脑瘤或蛛网膜囊肿的成年患者中使用时的安全性和性能。
通过查阅112例接受脑室腹腔分流手术并在术后随访一年的成年患者的病历生成数据。
结果显示，76%的患者神经症状得到改善，术后第一年的再次手术率为15%。
Sphera Duo®分流系统是几种原因导致的脑积水常规神经外科治疗中一种适用的分流选择。它在减轻过度引流影响的同时取得了良好效果。过度引流在非高血压性脑积水的成年人中尤为重要，可导致功能性分流失败，进而导致颅内压低于正常水平（尤其是在直立位时），并伴有典型的神经症状，如体位性头痛和恶心。
Sphera Duo®分流系统在患有脑积水、假性脑瘤或蛛网膜囊肿的成年患者中使用时是安全的。
