Summary
Remote cerebellar hemorrhage (RCH) after brain surgery is linked to aspirin use and high blood pressure. While often benign, RCH can be serious, highlighting the need to manage these risk factors.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Remote cerebellar hemorrhage (RCH) is a rare complication of supratentorial neurosurgery.
- The exact causes and risk factors for RCH remain poorly understood.
Purpose of the Study:
- To identify risk factors associated with RCH following supratentorial neurosurgical procedures.
- To compare patients with RCH to a matched control group.
Main Methods:
- Retrospective review of 42 patients with RCH after supratentorial neurosurgery (1988-2000).
- Case-matched control group of 43 patients.
- Analysis of medical records, including imaging findings and intraoperative parameters.
Main Results:
- RCH most frequently occurred after frontotemporal craniotomies for unruptured aneurysm repair or temporal lobectomy.
- Preoperative aspirin use and elevated intraoperative systolic blood pressure were significant risk factors (P=0.026 and P=0.036).
- Two patients experienced fatal outcomes; most cases were incidental findings.
Conclusions:
- RCH commonly follows supratentorial procedures involving cerebrospinal fluid opening, particularly in the supine position.
- Aspirin use and elevated systolic blood pressure are modifiable risk factors.
- Cerebellar sag due to CSF hypovolemia is the likely cause of RCH, leading to hemorrhagic venous infarction.

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...
01:29Hemorrhagic 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...
