What is a Supratentorial hemorrhage?
What is a Supratentorial hemorrhage?
Background. Remote postoperative hemorrhage is a known complication of spinal surgeries and occurs typically in the subdural space and the tentorial surface of the cerebellum.
What are the two types of hemorrhagic stroke?
Hemorrhagic strokes are divided into 2 main categories, including the following:
- Intracerebral hemorrhage. Bleeding is from the blood vessels within the brain.
- Subarachnoid hemorrhage. Bleeding is in the subarachnoid space (the space between the brain and the membranes that cover the brain).
What is the difference between intracerebral and subarachnoid hemorrhages?
Intraparenchymal hemorrhage (IPH; Figure 1) refers to nontraumatic bleeding into the brain parenchyma. (Intracerebral hemorrhage, often abbreviated ICH, is used more often in the clinical literature.) Subarachnoid hemorrhage (SAH) refers to bleeding into the space between the pia and the arachnoid membranes.
What is Supratentorial and Infratentorial?
In anatomy, the supratentorial region of the brain is the area located above the tentorium cerebelli. The area of the brain below the tentorium cerebelli is the infratentorial region. The supratentorial region contains the cerebrum, while the infratentorial region contains the cerebellum.
What is the position of choice for supratentorial craniotomy?
HOB , positioning, activity, bathing: The HOB after supratentorial craniotomy should be at least at 30 degrees. Avoidance of prolonged pressure directly on the incision will prevent breakdown or added discomfort.
What are the 3 different types of strokes?
What are the types of stroke?
- Ischemic stroke. Most strokes are ischemic strokes.
- Hemorrhagic stroke. A hemorrhagic stroke happens when an artery in the brain leaks blood or ruptures (breaks open).
- Transient ischemic attack (TIA or “mini-stroke”)

What are three types of intracranial hemorrhage?
There are three categories of hematoma — subdural hematoma, epidural hematoma and intracerebral (intraparenchymal) hematoma.
What is considered infratentorial?
The posterior fossa/infratentorial area (the lower back part of the brain) contains the cerebellum, tectum, fourth ventricle, and brain stem (midbrain, pons, and medulla).
What is infratentorial?
Medical Definition of infratentorial : occurring or made below the tentorium cerebelli an infratentorial tumor.
What is Supratentorial and infratentorial?
What is infratentorial craniotomy?
A surgical procedure to remove a brain tumor located in either the infratentorial or posterior fossa regions of the brain.
What causes eye hemorrhage?
Risk factors for a subconjunctival hemorrhage include: Diabetes. High blood pressure (hypertension) Certain blood-thinning medications, such as warfarin (Coumadin, Jantoven) and aspirin.
What is the difference between arterial and venous bleeding?
Arterial bleeding is when you bleed from an artery. Your arteries bring oxygen-rich blood away from your heart and to your body’s organs. Venous bleeding. In venous bleeding, blood flow comes from a vein.
How do you distinguish between ischemic and hemorrhagic stroke?
Hemorrhagic strokes occur when the brain loses access to its vital blood supply because of bleeding from a blood vessel. On the other hand, ischemic strokes happen when there is a blockage in one of the blood vessels feeding the brain.
What’s the difference between a hemorrhagic stroke and an ischemic stroke?
An ischemic stroke occurs when a blood vessel supplying the brain becomes blocked, as by a clot. A hemorrhagic stroke occurs when a blood vessel bursts, leaking blood into the brain.
What is the most common location of intracranial bleeding?
The commonest site of bleeding was basal ganglia followed by thalamus and cerebral hemispheres.
What is the difference between the supratentorial and infratentorial space?
In this conceptual coronal drawing the distinction between the supratentorial and infratentorial space is made apparent by the bright pink tentorium that acts as a roof of the posterior fossa. The forebrain and the upper part of the midbrain lie above the tentorium, and the lower midbrain and hindbrain lie below.
Is cerebellar intracerebral hemorrhage a type of infratentorial stroke?
Spontaneous intracerebral hemorrhage (ICH) is the most serious and least treatable type of stroke, 1 with prognosis strongly associated with location in the infratentorial compartment. 2 However, studies generally group cerebellar and brain stem ICH against supratentorial ICH in analyses, rather than subtyping infratentorial ICH.
What is supratentorial white matter disease?
Supratentorial white matter disease is a serious concern. Its effects can lead to permanent disability, and doctors are still learning about the disease. What they know is that it is preventable for those who take necessary precautions. It is more common among the elderly, whose bodies have been subjected…
What is the supratentorial region of the human brain?
The supratentorial region of the human brain is located above the tentorium cerebelli. The cerebrum is the largest part of the brain. About 40 percent of the brain consists of white matter, which contains nerve fibers called neurons that transmit pulses in the brain 2.
