Resumen
La enfermedad de descompresión tipo II (DCS) afecta al sistema nervioso central, no sólo a la médula espinal. Este estudio encontró déficits de perfusión cerebral en todos los casos graves de DCS, lo que sugiere una participación cerebral generalizada.
Área de la Ciencia:
- Neurología Neurología.
- Medicina de buceo para el buceo.
- Radiología Radiología.
Sus antecedentes:
- La enfermedad de descompresión (DCS) se clasifica típicamente en tipo I (leve, no neurológica) y tipo II (grave, neurológica).
- El DCS de tipo II se ha considerado principalmente una afección de la médula espinal con una rara implicación cerebral.
Objetivo del estudio:
- Para investigar la perfusión cerebral en buzos que experimentan enfermedad de descompresión (DCS) y embolia gaseosa arterial cerebral (CAGE).
- Reevaluar la clasificación y la comprensión del tipo II DCS.
Principales métodos:
- Utilizado 99Tcm-hexamethylpropyleneamine oxime inyección y tomografía por emisión de un solo fotón (SPECT).
- Perfusión cerebral evaluada en 28 buzos con incidentes confirmados de DCS y CAGE.
Principales resultados:
- Se observaron déficits de perfusión cerebral en los 23 casos de CCD de tipo II.
- Los 4 casos de embolia de gas arterial cerebral (CAGE) presentaron déficits de perfusión.
- No se encontraron déficits de perfusión cerebral en el único caso de DCS Tipo I.
Conclusiones:
- El tipo II DCS debe ser reconocido como una enfermedad difusa, multifocal del sistema nervioso central.
- La participación cerebral es común en el tipo II DCS, desafiando las suposiciones anteriores.

01:21Peripheral 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...
01:15Ischemic 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...
01:29Increased 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...
01:19Cerebral 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...
01:22Cerebral 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...
01:21Cytotoxic 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...
