Most patients who undergo cavernoma surgery are free of the neurological symptoms that beset them when they had the cavernoma and go on to lead a normal life, according to the American Association of Neurological Surgeons. Symptoms of a cavernoma may include seizures, weakness in the patient's arms and legs, problems with balance and vision, problems with attention and memory, and headaches.
The minority of patients who still suffer neurological problems after surgery are no worse off than they were before the surgery and in some cases improve after therapy, though this may take a long time, says the American Association of Neurological Surgeons. Rebleeding is a problem in some patients.
Surgery is recommended when the symptoms caused by a cavernoma cannot be controlled by medications and the cavernoma is located in a relatively accessible place in the brain, according to the American Association of Neurological Surgeons. The physician also needs to confirm that the cavernoma is causing the patient's symptoms.
Microsurgery is used to remove cavernomas, as stated by Neurosurgeons at Macquarie University Hospital. During this surgery, a bit of the patient's skull that lies over the cavernoma is removed, and the lesion is removed with the aid of a computer.
