- 神経外科は神経外科です.
- ストローク医学は,脳卒中医学である.
背景:
- 早期の神経学的悪化 (END) は,脳内出血 (ICH) 患者におけるアウトカムを著しく悪化させる.
- ENDを予測することは, supratentorial ICH.のタイムリーな介入に不可欠です.
- 現在の予測モデルでは,場所固有のリスクが完全に捉えられていない可能性があります.
研究 の 目的:

- これらの値に基づいて,ENDを予測するための新しいスコア (LIVED) を開発し,検証する.
主な方法:
- 2つの潜在的なコホートから1199人の supratentorial ICH患者の遡及的分析.
- ENDの定義: 24時間以内にNIHSSの上昇≥4ポイントまたはGCSの減少≥2ポイント.
- 訓練,内部,および外部コホートを使用してLIVEDスコアの開発と検証.
主要な成果:
- ENDの特定された血腫容量の値: 21mL (ベースガンリア),12mL (タラムス),32mL (ロバー).
- LIVEDスコアは,場所特有の体積と他の要因を組み込み,END (AUC > 0.70) を予測する上で既存のICHスコアを上回った.
- また,LIVEDスコアは,3ヶ月のアウトカム (機能的独立性,悪いアウトカム,死亡率) に対して強い差別を示した.
結論:
- 場所固有の血腫容量は, supratentorial ICH.におけるENDの独立した予測因子である.
- LIVEDスコアは,これらの患者におけるENDおよび3ヶ月のアウトカムに対する信頼性の高いリスク分層化を可能にします.

01:17Hemorrhagic Stroke l: Introduction
34
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

01:29Hemorrhagic Stroke ll: Pathophysiology
52
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

30
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...

01:29Increased Intracranial Pressure ll: Pathophysiology
39
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...

01:22Cerebral Edema ll: Pathophysiology
31
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...
