What is subarachnoid bleeding?

subarachnoid bleeding is a type of stroke characterized by bleeding in the area between the Arachnoid membrane and the PIA mater, two membranes that obscure the brain. Arachnoid membrane and PIA Mater are the two innermost mening, membranes covering the structures of the central nervous system. The PIA mater is delicate and adheres to the brain surface, while the arachnoid layer is made of connective tissue similar to spiders and helps to pour the central nervous system. Subarachnoidal bleeding may be caused by a trauma of the head or a cracked aneurysm in the brain.

The most common symptom of subarachnoid bleeding is suddenly, intense headache known as headache. Many patients do not experience any other symptoms. Vomiting, delirium, neck stiffness, seizures, coma and weakness on one side of the body may also be accompanied by subarachnoid bleeding.

In severe cases, the herniation can occur, resulting in the expansion of one pupil and the pupil's failure to respond to the light. IntraoculeArary or subhyaloid bleeding, eye bleeding or its surrounding membrane also rarely occurs. Subarachnoidal bleeding also triggers the release of adrenaline and other hormones, resulting in an increase in blood pressure and an increased rhythm of the heart. Cardiac arrhythmias, accumulated fluid in the lungs and even cardiac arrest can follow.

Subarachnoidal bleeding is most often caused by a cracked brain aneurysm, a weakened area in the brain artery that increases. Other possible causes include other blood vessel disorders, head damage, cocaine abuse, sickle -like anemia and blood clotting disorders or anticoagulant drugs. Subarachnoid bleeding is always emergency and should be treated as soon as possible. Half of all cases are fatal and many people who survive suffer from cognitive or neurological damage.

Subarachnoid Hempacients ORHAGE are stabilized as quickly as possible.Depending on the severity of the condition, the blood is required to remove the blood and the closure of the bleeding site. Other patients are stabilized for a longer period of time and are subject to femoral angiogram to discover the source of bleeding. Aneurysm can be treated by trimming or sting. Cropping requires the opening of the skull and the location of the artery clips around the aneurysm, while the winding is carried out by a catheter through the arteries and platinum coils by aneurysm, causing a blood clot that destroys aneurysm.
