Insights

Anticoagulants and antiplatelet agents are increasingly significant risk factors for chronic subdural hematoma (CSDH). Careful prescription of these medications is advised due to their growing importance in CSDH development.

Area of Science:

  • Neurosurgery
  • Geriatrics
  • Pharmacology

Background:

  • Chronic subdural hematoma (CSDH) is a common neurosurgical condition.
  • Medications causing coagulopathies, like anticoagulants (ACs) and antiplatelet agents (APs), are known CSDH risk factors.
  • Increasing use of ACs/APs, particularly in the elderly, necessitates re-evaluation of CSDH risk factors.

Purpose of the Study:

  • To investigate the changing trends of risk factors for chronic subdural hematoma (CSDH).
  • To analyze the specific impact of anticoagulants (ACs) and antiplatelet agents (APs) on CSDH development over time.

Main Methods:

  • Retrospective review of 290 CSDH patients undergoing surgery between 1996 and 2010.
  • Classification of patients into three groups based on presentation period: 1996-2000, 2001-2005, and 2006-2010.
  • Comparative analysis of independent risk factors, including ACs/APs use, across the three time periods.

Main Results:

  • The proportion of CSDH patients using ACs/APs significantly increased over time (4.2% to 15.7%).
  • In the recent period (2006-2010), ACs/APs-related CSDH cases showed a lower association with trauma or alcohol compared to non-medication groups.
  • The number of CSDH patients increased across the study periods, with the recent group having the highest proportion (41.7%).

Conclusions:

  • Anticoagulants and antiplatelet agents have emerged as increasingly important risk factors for chronic subdural hematoma.
  • The association between ACs/APs and CSDH is becoming more prominent, with a reduced role for traditional risk factors like trauma and alcohol in medication-associated cases.
  • Healthcare providers should carefully consider the risk-benefit profile when prescribing ACs/APs due to their growing contribution to CSDH.

Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic 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...

Hemorrhagic 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...
Increased Intracranial Pressure l: Introduction01:14

Increased 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...
Increased Intracranial Pressure ll: Pathophysiology01:29

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 ll: Pathophysiology01:22

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...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
