What is pontine bleed?
Pontine hemorrhage, a form of intracranial hemorrhage, is most commonly due to long standing poorly-controlled chronic hypertension. It carries a very poor prognosis.
What are the symptoms of pontine hemorrhage?
The symptoms at onset were headache and vomiting in 10 patients, vertigo in seven, hemiparesis in six, loss of consciousness in five and unilateral sensory disturbance in two.
What causes pons bleed?
Causes of pontine haemorrhages which have an incidence of 2 to 4/100 000/year include hypertension, vascular malformations (a.v.-haemangioma, cavernous haemangioma, capillary teleangiectasies), anticoagulative treatment and inflammatory vascular disease.
Is pontine hemorrhage a stroke?
A stroke occurs when the supply of blood to the brain is compromised by either a clogged artery (called an ischemic stroke) or burst artery (called a hemorrhagic stroke). When stroke happens in the pons, which is the upper section of the brain stem, it’s called a pontine stroke.
What does the Pontine do?
The pons is part of a highway-like structure between the brain and the body known as the brainstem. The brainstem is made up of three sections, and carries vital information to the body. The pons relays information about motor function, sensation, eye movement, hearing, taste, and more.
Where is a pontine hemorrhage?
Features typical of an acute intraparenchymal hemorrhage are noted, usually located centrally within the pons (on account of the larger paramedian perforators usually being the site of bleeding).
What is the meaning of Pontine?
Listen to pronunciation. (PON-teen) Having to do with the pons (part of the central nervous system, located at the base of the brain, between the medulla oblongata and the midbrain). Enlarge.
Why is there hyperthermia in pontine hemorrhage?
Prolonged central hyperthermia following pontine hemorrhage is a very rare disease, caused by failures of thermoregulatory pathways at the brainstem. Although central hyperthermia has been known for a long time, our knowledge remains limited.
What will happen if pons is damaged?
Pons also relays sensory information and signals governing sleep patterns. If pons is damaged, it may cause loss of all muscle function except for eye movement.
How serious is a pontine stroke?
A pontine stroke can be particularly devastating and may lead to paralysis and the rare condition known as Locked-in Syndrome (LiS). Fortunately, it has been estimated that up to 80 percent of strokes are preventable.
What happens if there is damage to the medulla?
It plays an essential role in passing messages between your spinal cord and brain. It’s also essential for regulating your cardiovascular and respiratory systems. If your medulla oblongata becomes damaged, it can lead to respiratory failure, paralysis, or loss of sensation.
What will happen if the pons is damaged?
If pons is damaged, it may cause loss of all muscle function except for eye movement.
What is a pontine cerebrovascular accident?
A pontine cerebrovascular accident (also known as a pontine CVA or pontine stroke) is a type of ischemic stroke that affects the pons region of the brain stem. A pontine stroke can be particularly devastating and may lead to paralysis and the rare condition known as Locked-in Syndrome (LiS).
What is the prognosis of primary pontine hemorrhage?
Pontine hemorrhage, a form of intracranial hemorrhage , is most commonly due to long standing poorly-controlled chronic hypertension. It carries a very poor prognosis. Primary pontine hemorrhage accounts for ~7.5% (range 5-10%) of hemorrhagic strokes and has an incidence of ~3 per 100,000 people 6.
What is pontine stroke and what are the symptoms?
Pontine stroke, also known as pons stroke, is a type of brain stem stroke that often creates chronic side effects. Understanding the symptoms and treatment for pontine stroke is crucial, because timely treatment can help save a person’s life.
What is mid-pontine base infarction?
Mid-pontine base infarction is also due to decreased blood flow in the paramedian arteries or the short circumferential arteries arising from the basilar artery. Presenting symptoms depend on the extent of involvement of various structures within the pons.
