What is Subarachnoid Brain Hemorrhage?
A Subarachnoid Brain Hemorrhage is a condition where there is bleeding into the subarachnoid space which is the area between the arachnoid membrane and pia mater around the brain. The most common cause for this is a head injury. It may also occur spontaneously due to a ruptured cerebral aneurysm.
Causes of Subarachnoid Brain Hemorrhage
Subarachnoid Brain Hemorrhage can occur due to direct impact to the head resulting in a head injury such as getting hit on the head by a hard object, car accidents or falling and landing on the head. It can occur spontaneously due to a ruptured cerebral aneurysm. This occurs in individuals who have high blood pressure and are smokers between the ages of 20-60. Women are slightly more affected than men.
Symptoms of Subarachnoid Brain Hemorrhage
- Severe headache usually present at the back of the head.
- Nausea and vomiting.
- Change in consciousness.
- Sensitivity to bright lights.
- Alteration in breathing and pulse rates.
- Loss of consciousness.
Treatment of Subarachnoid Brain Hemorrhage
- Immediate medical attention should be sought.
- CT Scan, MRI scan or angiography helps in confirming a hematoma.
- Usually, surgery is required.
- The aim of surgery is to remove the blood/hematoma and decrease the pressure on the brain.
- If the cause of bleeding is ruptured aneurysm, then surgery is done to repair the aneurysm and drain the blood.
- After the surgery, the patient is closely monitored for any change in his/her condition which may indicate additional bleeding or brain injury.
