Study Notes
Types of Intracranial Bleeding
- Intraparenchymal hemorrhage: Bleeding within the brain tissue itself
- Intraventricular hemorrhage: Bleeding within the ventricles, the fluid-filled spaces within the brain
- Subarachnoid hemorrhage: Bleeding between the arachnoid membrane and the pia mater, the two innermost layers of the meninges
- Epidural hemorrhage: Bleeding between the dura mater and the skull
- Subdural hemorrhage: Bleeding between the dura mater and the arachnoid membrane
Causes of Intracranial Bleeding
- Trauma: Head injury, falls, motor vehicle accidents
- Hypertension: High blood pressure, leading to rupture of blood vessels
- Aneurysms: Weakened areas in blood vessels that can rupture
- Arteriovenous malformations (AVMs): Abnormal connections between arteries and veins
- Cerebral amyloid angiopathy: Buildup of abnormal proteins in blood vessels
- Blood clotting disorders: Conditions such as hemophilia
- Infections: Meningitis, encephalitis, and other infections that can cause bleeding
Symptoms of Intracranial Bleeding
- Headache: Sudden, severe, and worsening headache
- Nausea and vomiting: Especially in cases of increased intracranial pressure
- Confusion and disorientation: Altered mental status, difficulty speaking or understanding speech
- Seizures: Especially in cases of bleeding near the cerebral cortex
- Weakness or numbness: In the face, arms, or legs, depending on the location of the bleeding
- Vision changes: Blurred vision, double vision, or loss of vision
Diagnosis of Intracranial Bleeding
- Computed Tomography (CT) scan: Quick and effective way to diagnose bleeding
- Magnetic Resonance Imaging (MRI): More detailed imaging, but may not be as readily available
- Lumbar puncture: Collecting cerebrospinal fluid to check for blood
- Angiography: Imaging of blood vessels to diagnose aneurysms or AVMs
Treatment of Intracranial Bleeding
- Surgical evacuation: Removing the blood clot and repairing damaged blood vessels
- Endovascular coiling: Using a catheter to insert a coil to block the bleeding blood vessel
- Craniotomy: Temporarily removing part of the skull to relieve pressure
- Supportive care: Managing blood pressure, preventing complications, and providing rehabilitation
Test your knowledge on intracranial bleeding, including its types, causes, symptoms, and diagnosis methods. Learn about the different types of bleeding, such as intraparenchymal and subarachnoid hemorrhage, and how to diagnose them using CT scans, MRI, and other methods.
