まとめ
II型減圧性疾患 (DCS) は,脊髄だけでなく,中枢神経系にも影響を及ぼします. この研究では,すべての重度のDCS症例で脳 perfusion deficitが認められ,広範な脳関わりを示唆しています.
科学分野:
- 神経学 神経学とは
- ダイビング医学はダイビング医学です.
- 放射線学 放射線学
背景:
- 減圧性疾患 (DCS) は通常,タイプI (軽度,神経学的でない) とタイプII (重度,神経学的) に分類される.
- II型DCSは,まれに脳に関わる脊髄疾患と考えられてきました.
研究 の 目的:
- 解圧性疾患 (DCS) と脳動脈ガス栓塞 (CAGE) を経験しているダイバーの脳 perfusion を調査する.
- タイプII DCSの分類と理解を再評価する.
主な方法:
- 99Tcm-ヘクサメチルプロピレンアミンオキシム注射と単光子放射トモグラフィ (SPECT) を利用しました.
- 確認されたDCSおよびCAGEのインシデントを持つ28人のダイバーで脳 perfusion を評価しました.
主要な成果:
- 脳の perfusion deficits は,タイプII DCS の23例すべてで観察されました.
- 4人の脳動脈ガス栓塞 (CAGE) 症例はすべて, perfusion deficits を表した.
- 単一のタイプI DCS症例では,脳 perfusion deficit は見つかりませんでした.
結論:
- II型DCSは,分散型,多焦点の中枢神経系疾患として認識されるべきである.
- II型DCSでは脳の関与が一般的であり,以前の仮定に異議を唱える.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
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...
Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Cerebral Edema ll: Pathophysiology
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 barrier loses...
Cytotoxic Edema: Pathophysiology
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
