#128 Intracerebral Haemorrhage Surgery (English)

Intracerebral Haemorrhage Surgery

 Intracerebral haemorrhage occurs when a weakened or diseased blood vessels rupture, so the blood leaks inside the brain. The abrupt increase in pressure within the brain (hypertension) prompt the brain cells surrounding the blood to damage. When the amount of blood released increases rapidly, the sudden buildup in pressure can spur unconsciousness or death. Intracerebral haemorrhage usually occurs basal ganglia, cerebellum, brain stem, or cortex.

 Hypertension is one the most typical factors causing intracerebral haemorrhage. It often doesn't cause any symptoms. Consequently, majority of patients suffering from Intracerebral haemorrhage are not aware that they have high blood pressure. The other factors like head trauma, aneurysm, arteriovenous malformations, amyloid angiopathy, liver disease, and brain tumors lead to intracerebral haemorrhage.

Aneurysm is a weakening in a blood vessel wall that swells.
Arteriovenous malformations are the weaknesses in the blood vessels in and around the brain.
Amyloid angiopathy is an abnormality of the blood vessel walls.

 There are various surgeries regarding intracerebral haemorrhage: decompression surgery, craniotomy with open surgery, simple aspiration, endoscopic evacuation, and stereotactic aspiration. The surgery will proceed depending on the age, the other health issues that the patient might possess, the degree of brain damage, and the location of the haemorrhage and haematoma.

 Decompression surgery is alleviating the blood pressure by removing the pooled blood and repairing damaged blood vessels. Pooled blood is the blood that could not return to the heart due to the malfunctioning of the walls and valves of veins in the brain. Evacuating haematoma, a solid swelling of clotted blood within the tissues, relieves the blood pressure.

 Craniotomy with open surgery is the removal of a portion of the skull accompanied by the open surgery to evacuate the haematoma and repair the ruptured blood vessel. This is a surgical procedure that is used when the haematoma is very large, so the critical functions weaken.

 Simple aspiration is when the surgeon drills a small hole in the skull and evacuates the haematoma using a needle. Finding the exact location of haematoma is demanding. Also, the complete evacuation of haematoma is not possible.

 Endoscopic evacuation involves drilling a hole in the skull like simple aspiration but it is a more acute procedure as it involves using an endoscope to navigate the needle. Endoscope is a tiny camera-guided instrument.

 Stereotactic aspiration proceeds the surgery based on the computed tomography (CT) that indicates the location of the haematoma. Also, the evacuation of haematoma is done by a specially developed suction too. During this surgery, the patient’s head is fixed in a stereotactic head frame, so the procedure is done at a greater degree of precision and accuracy.
