A surgical procedure done to treat a ruptured brain aneurysm is known as brain aneurysm surgery.
A brain aneurysm is a ballooning or bulging in a blood vessel in the brain.
Most types of brain aneurysms do not cause any health problems and are often detected during testing for other conditions.
However, if a brain aneurysm leaks or ruptures it can lead to life-threatening bleeding into the brain, known as a hemorrhagic stroke. Therefore, a ruptured aneurysm requires prompt medical treatment.
Symptoms: The symptoms of an unruptured aneurysm may include:
The symptoms of a ruptured aneurysm, which may require a brain aneurysm surgery include:
Physical examination: The doctor will check the symptoms of the patient to diagnose a brain aneurysm.
CT scan and MRI scan: These are imaging tests done to obtain clear images of the brain and check if you have bleeding in the brain.
MRI angiography: It is a type of MRI that is used to assess the arteries in detail to detect the presence of a brain aneurysm.
Cerebrospinal fluid test: In case the patient has symptoms of a ruptured aneurysm which is not visible on the CT scan, the surgeon draws cerebrospinal fluid (the fluid surrounding the brain and spine) from the back using a needle to check for the presence of red blood cells, which may indicate a hemorrhage. This procedure of drawing cerebrospinal fluid is known as a spinal tap or lumbar puncture.
Cerebral angiogram or cerebral arteriogram: The doctor will insert a catheter (a thin, flexible tube) into an artery usually in the groin area, and guide it past the heart into the brain arteries. A dye is then injected into the catheter, which travels to the arteries in the brain. A series of x-rays are then taken to detect an aneurysm.
A brain aneurysm can be corrected using the following surgical procedures:
The surgeon makes an incision into the scalp.
A hole is created in the skull.
A small metal clip is then placed at the base of the aneurysm to prevent the rupture of the aneurysm.
The skull is then closed and the scalp is stitched (sutures).
2. Endovascular repair:
The surgeon makes a small incision in the groin area.
A catheter is then guided through the incision leading to the brain aneurysm.
The surgeon inserts a thin metal (platinum) wire into the aneurysm through the catheter tube, using a guide wire.
The platinum wire coils into a ball and initiates the formation of a blood clot.
This blood clot prevents the rupture of the brain aneurysm and also seals off the brain aneurysm from the artery.
The potential complications of brain aneurysm surgery are:
Blood clot formation
Allergic reaction to the anesthetic used
Lack of co-ordination
Stroke (a condition in which the blood supply to the brain is stopped)
