Summary
Organized hematoma with thick membranes (OHTMF) is a cause of chronic subdural hematoma (CSH) recurrence. Radical treatment like craniotomy with membranectomy is recommended to prevent CSH reoccurrence.
Area of Science:
- Neurosurgery
- Neurology
- Medical Research
Background:
- Chronic subdural hematoma (CSH) can involve organized hematoma with thick membranes (OHTMF), leading to surgical complications and recurrence.
- Limited data exists on OHTMF prevalence and outcomes in Nepal.
- Understanding OHTMF is crucial for improving CSH surgical management.
Purpose of the Study:
- To determine the prevalence of OHTMF in chronic subdural hematoma (CSH) cases in Nepal.
- To investigate the complications associated with OHTMF.
- To evaluate the effectiveness of surgical interventions for OHTMF.
Main Methods:
- A multicentric retrospective analytical study was conducted.
- One hundred cases of CSH were analyzed between early 2006 and August 2010.
- Focus was placed on identifying and analyzing cases with OHTMF.
Main Results:
- OHTMF was identified in 3% (3 out of 100) of CSH cases.
- These 3 cases required craniotomy with radical membranectomy.
- One case of CSH recurrence after single burr hole evacuation was successfully treated with craniotomy and membranectomy, with no further recurrence.
Conclusions:
- OHTMF is a significant factor contributing to CSH recurrence.
- Radical surgical treatment, including membranectomy, is essential for managing OHTMF.
- Further research into the hypotheses behind OHTMF formation is warranted.

01:19Cranial and Spinal Meninges
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

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...
01:29Hemorrhagic 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...
01:17Hemorrhagic 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...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
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...
