Idiopathic normal pressure hydrocephalus (iNPH) affects approximately 1.5% of the population, with a higher prevalence in men than women. Ventriculoperitoneal shunting (VPS) is the standard treatment for iNPH, but it poses a notable risk of infection, occurring in 8-10% of cases. Recent advancements in non-invasive diagnostic techniques, such as superb microvascular ultrasound (SMI), have demonstrated potential in evaluating cerebrospinal fluid (CSF) flow within VPS systems. A single-center feasibility study involving 19 asymptomatic patients with VPS systems showed that SMI reliably detected CSF flow in the proximal catheter in all patients and in the distal catheter in 89.5%, while reductions in optic nerve sheath diameter (ONSD) indicated lowered intracranial pressure after shunt activation. These findings suggest that SMI could serve as a safer alternative to invasive methods for assessing shunt function. Additionally, artificial intelligence (AI)-based approaches are being explored to reduce infection risk and enhance shunt efficacy. An artificial neural network (ANN) model achieved an 83.1% accuracy in predicting infection risk, surpassing traditional logistic regression models. However, the study's limitations, including its retrospective design, small sample size, and single-center nature, underscore the need for larger multi-center studies to confirm the generalizability of these findings. Further research is essential to validate the effectiveness of these innovations and their potential to improve patient outcomes in hydrocephalus management.
特发性正常压力脑积水(iNPH)影响约 1.5%的人口,男性患病率高于女性。脑室腹腔分流术(VPS)是 iNPH 的标准治疗方法,但它存在显著的感染风险,约 8-10%的病例会发生感染。最近,无创诊断技术如超级微血管超声(SMI)的进展表明,其在评估 VPS 系统中的脑脊液(CSF)流动方面具有潜力。一项涉及 19 例无症状 VPS 系统患者的单中心可行性研究表明,SMI 可靠地检测到所有患者近端导管中的 CSF 流动,并在 89.5%的患者中检测到远端导管中的 CSF 流动,同时视神经鞘直径(ONSD)减小表明分流激活后颅内压降低。这些发现表明,SMI 可以作为评估分流功能的更安全替代方法,替代有创方法。此外,还在探索基于人工智能(AI)的方法来降低感染风险并提高分流效果。人工神经网络(ANN)模型在预测感染风险方面的准确率达到 83.1%,超过了传统的逻辑回归模型。然而,该研究的局限性,包括回顾性设计、样本量小和单中心性质,突出了需要进行更大规模的多中心研究来确认这些发现的普遍性。进一步的研究对于验证这些创新的有效性及其在脑积水管理中改善患者预后的潜力至关重要。
