Vascular neurosurgery

 

Spontaneous intracranial haemorrhage may result in clot formation within the brain itself or on the surface of the brain. Vascular diseases of the central nervous system can either be treated by open surgery or endovascular means depending on the pathology.

When the haemorrhage is due to a ruptured aneurysm, patients may need to be transferred to a unit where endovascular treatment is available. Under certain circumstances a craniotomy may need to be performed to evacuate a haematoma or place a clip over the neck of the aneurysm.

Diagnosis of vascular abnormalities is done with angiography using CT, MRI or Digital subtraction angiography.
