Intracranial hemorrhage (ICH), also known as intracranial bleed, is bleeding within the skull. [1] Subtypes are intracerebral bleeds (intraventricular bleeds and intraparenchymal bleeds), subarachnoid bleeds, epidural bleeds, and subdural bleeds. [2] Intracerebral bleeding affects 2.5 per 10,000 people each year. [1]
Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e. the parenchyma), into its ventricles, or into both. [ 3 ] [ 4 ] [ 1 ] An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other).
The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or major disability than ischemic stroke or subarachnoid hemorrhage, and therefore constitutes an immediate medical emergency.
The broad term, "stroke" can be divided into three categories: brain ischemia, subarachnoid hemorrhage and intracerebral hemorrhage. Brain ischemia can be further subdivided, by cause, into thrombotic, embolic, and hypoperfusion. [3] Thrombotic and embolic are generally focal or multifocal in nature while hypoperfusion affects the brain globally.
In contrast, intracranial hemorrhage involves bleeding that is not mixed with tissue. [37] Hematomas, also focal lesions, are collections of blood in or around the brain that can result from hemorrhage. [11] Intracerebral hemorrhage, with bleeding in the brain tissue itself, is an intra
A ruptured microaneurysm may cause an intracerebral hemorrhage, presenting as a focal neurological deficit. [ 12 ] Rebleeding, hydrocephalus (the excessive accumulation of cerebrospinal fluid ), vasospasm (spasm, or narrowing, of the blood vessels), or multiple aneurysms may also occur.
Epidural hemorrhage is bleeding between the dura mater and the skull. [4] It is commonly associated with damage to the middle meningeal artery, often resulting from a skull fracture. Subdural hemorrhage is bleeding between the dura mater and the arachnoid. [4] Intracerebral hemorrhage is bleeding within the brain tissue itself. [4]
**Mechanism of Intraventricular Hemorrhage (IVH)** **Definition** Intraventricular hemorrhage (IVH) refers to bleeding into the brain's ventricular system, where cerebrospinal fluid (CSF) is produced and circulates. IVH can occur in both neonates and adults, but the mechanisms differ based on age and underlying causes. --- **1.
