intracranialaneurysm

What is intracranial aneurysm?


A brain aneurysm is an abnormal bulge or "ballooning" in the wall of an artery in the brain. They are sometimes called berry aneurysms because they are often the size of a small berry. Most brain aneurysms produce no symptoms until they become large, begin to leak blood, or rupture. If a brain aneurysm presses on nerves in your brain, it can cause signs and symptoms. These can include:

Actiq

ACTIQ (oral transmucosal fentanyl citrate) is a solid formulation of fentanyl citrate, a potent opioid analgesic, intended for oral transmucosal administration. ACTIQ is formulated as a white to off-white solid drug matrix on a handle that is fracture resistant (ABS plastic) under normal conditions when used as directed. ACTIQ is an opioid analgesic indicated only for management of breakthrough cancer pain in patients 16 and older with malignancies who are already receiving and who are tolerant to opioid therapy for their underlying persistent cancer pain.

Aneurysm, Brain
An aneurysm is an abnormal widening or ballooning of a portion of a blood vessel. A cerebral aneurysm refers to a blood vessel within your brain that weakens over time and undergoes such widening. This usually occurs at the junctions of the large arteries at the base of your brain, in an area called the Circle of Willis. As the blood vessel weakens, it begins to bulge out like a balloon. Often, as an aneurysm develops, it forms a neck with an associated dome, or balloonlike structure. The larger the balloon becomes, the greater the risk it may burst. You would then bleed into your brain.

Brain aneurysm
A brain aneurysm (AN-u-rizm) is a bulge or ballooning in a blood vessel in the brain. It often looks like a berry hanging on a stem.

Aneurysm
In most cases, an unruptured aneurysm will cause no symptoms unless it grows particularly large or, in the case of a intracranial aneurysm, begins to press against tissues or nerves inside the brain.

Intracranial hematoma
An intracranial hematoma occurs when a blood vessel ruptures within your brain or between your skull and your brain. The collection of blood (hematoma) compresses your brain tissue.

Brain haemorrhage
A subarachnoid haemorrhage is a serious and potentially life-threatening condition where blood leaks out of blood vessels over the surface of the brain. It is known as a subarachnoid haemorrhage because the bleeding occurs in the arteries that run underneath a membrane or layer in our brain called the arachnoid, which is just below the surface of the skull.

Hemorrhagic stroke
A hemorrhagic stroke is a condition that happens when a blood vessel in the brain bursts. Blood leaks out and can irritate or injure the brain tissue, or cause damage by pushing into nearby areas. Other blood vessels may get pinched and stop blood flow to areas of the brain. Blood carries oxygen and other nutrients to the brain. When blood does not reach all parts of the brain, brain cells may be damaged or die. A hemorrhagic stroke may begin suddenly, develop quickly, and cause death of brain tissue within minutes or hours. Death of an area of the brain may cause the body functions controlled by that area to be lost. Body functions, such as walking or talking, are controlled by certain areas of your brain. Having a hemorrhagic stroke may cause you to die or lose some body functions forever.

Pseudotumor cerebri
Pseudotumor cerebri (SOO-doh-too-mur SER-uh-bry) occurs when the pressure inside your skull (intracranial pressure) increases for no obvious reason. Symptoms mimic those of a brain tumor, but no tumor is present. Pseudotumor cerebri can occur in children and adults, but it's most common in obese women of childbearing age.

Pentazocine and Acetaminophen
Head Injury and Increased Intracranial Pressure. As in the case of other potent analgesics, the potential of pentazocine for elevating cerebrospinal fluid pressure may be attributed to CO2 retention due to the respiratory depressant effects of the drug. These effects may be markedly exaggerated in the presence of head injury, other intracranial lesions, or a pre-existing increase in intracranial pressure. Furthermore, pentazocine can produce effects which may obscure the clinical course of patients...
