概括

腰部输液试验 (LIT) 有助于诊断异常性正常压力头症 (iNPH),当其他测试没有确定性时. 这种安全,有价值的工具有助于改善移位后的患者结果.

科学领域:

神经学神经学
神经外科神经外科
诊断成像诊断成像诊断成像

背景情况:

异常性正常压力脑症 (iNPH) 存在诊断挑战,原因是缺乏单一的确定的测试.
准确的诊断对于及时干预和管理至关重要.

研究的目的:

评估腰部输液试验 (LIT) 在指导疑似iNPH患者的分流决策方面的有效性.
评估LIT的性能与临床和放射学评估一起进行.

主要方法:

201名疑似iNPH患者的队列接受了全面的临床,放射和水力动力学评估,包括LIT.
在LIT之前和之后,患者被分为诊断组 (不太可能,可能,可能的iNPH).
分析了耐药系数 (Rout) 值的灵敏度和特异性,并评估了移动后的临床结果.

主要成果:

诊断组的LIT显示了诊断组的平均路线值的显著变化 (P < .0001).
12 mm Hg/mL/min的最佳路特值显示了78.1%的灵敏度和74.3%的特异性 (AUC = 0.8441).
在根据LIT发现进行了变流的患者中,75.6%至87.1%的患者表现出临床改善.

结论:

腰部输液试验 (LIT) 是诊断iNPH的安全和有价值的辅助方法,特别是在诊断不确定的情况下.
LIT有助于早期决策,并有可能改善手术后的结果.
它的可复制性,易用性和低发病率使得LIT在与临床和放射学数据相结合时成为一种有用的工具.

Increased Intracranial Pressure l: Introduction

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Increased Intracranial Pressure ll: Pathophysiology

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
