Summary
This study quantified chronic subdural hematoma (CSDH) pressure, finding a mean of 15.2 cm H2O. Larger CSDHs with significant midline shifts had higher pressures and more repeat surgeries.
Area of Science:
- Neurosurgery
- Neurology
- Medical Physics
Background:
- Chronic subdural hematoma (CSDH) surgery aims to reduce brain displacement and intracranial pressure (ICP).
- Intraoperative CSDH pressure often appears low despite severe symptoms, creating a diagnostic challenge.
Purpose of the Study:
- To quantify CSDH pressure using a manometric technique.
- To correlate CSDH pressure with radiological and clinical characteristics.
- To investigate factors influencing CSDH pressure and surgical outcomes.
Main Methods:
- Prospective, population-based study of unilateral CSDHs over 3 years.
- Exclusion of secondary CSDHs, re-operations, and complex procedures.
- Standardized protocol for subdural pressure registration via manometry in 60 patients.
Main Results:
- Mean CSDH pressure was 15.2 cm H2O (range 0-40 cm H2O), with no gender difference.
- Men had larger hematoma volumes and midline shifts than women.
- Larger hematomas with greater midline shifts showed higher pressures and increased need for repeat surgery. Older patients had larger volumes/shifts but lower pressures.
Conclusions:
- CSDH pressure measurements provide objective data, contrasting with subjective clinical assessments.
- Mean CSDH pressure is comparable to normal ICP, suggesting complex pathophysiology.
- Hematoma size, midline shift, and age influence CSDH pressure, impacting surgical outcomes and management strategies.

01:14Increased 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...
01:17Hemorrhagic Stroke l: Introduction
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...
01:29Increased 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...
01:29Hemorrhagic Stroke ll: Pathophysiology
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...
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...
01:19Cerebral 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...
