Parkinson's Surgery

"The ideal candidate for a subthalamotomy is the patient with symptoms and signs of Parkinson's that are eminently unilateral and have been present for several years, as well as those who, for some specific reason, cannot have a stimulator implanted".

DR. JORGE GURIDI
DIRECTOR. NEUROSURGERY DEPARTMENT

Surgery for Parkinson's disease is indicated when drug treatment fails to control the patient's symptoms throughout the day.

It is performed with deep brain stimulation. To achieve this, high frequency stimulation is performed in a small part of the brain called the subthalamic nucleus by placing electrodes. Through electrical impulses, it is possible to inhibit the part of the brain that is hyperactive and causes the disease.

Parkinson's is a disease without cure at present, but the benefits obtained through surgery are clear: it achieves a regression of the disease equivalent to years of evolution. In particular, there are improvements in movement, as well as a decrease in the rigidity and tremors of patients.

It also makes it possible to reduce medication, which avoids the psychiatric side effects of the drugs.

When is Parkinson's surgery indicated?

Surgery is performed on those patients who do not tolerate drug treatment well or do not find it effective, as well as on those who are particularly incapacitated by the disease.

The surgical success is related to the selection of the candidate, the good placement of the electrode in the brain and the achievement of a good stimulation and medication. 

Most frequent indications for this treatment:

  • Parkinson's disease.

HIFU, treatment of tremor and other Parkinson's symptoms without surgery

The Clinica Universidad de Navarra incorporates the most advanced model of high intensity ultrasound for the treatment of patients with tremor of Parkinson's disease.

How is Parkinson's surgery performed?

The first step consists of performing a cerebral magnetic resonance, whose images are later used by a neuronavigation program. The MRI is used to calculate the coordinates of the area where the stimulating electrodes will be inserted.

A small incision is made in the scalp and then a hole of approximately 1 cm is opened in the skull (stereotaxy). Thanks to the orientation offered by an electrophysiological record of neuronal activity, the exact point in which to place the electrical stimulator is located.

The intervention is carried out under local anesthesia and the patient is conscious during its development, so you can work with the surgical team to know the effect of the stimulation before the final implantation of the electrode.

The second part of the treatment is carried out a few days later under general anesthesia and consists of placing the connection wires and the pacemaker or battery that supplies the electrical stimulation under the skin. Usually, the pacemaker is inserted under the collarbone.

Deep brain stimulation is a reversible intervention in case of side effects or if the result is not as expected.

After the surgery, the patient must go to periodic controls with his neurologist. Sometimes, if the symptoms change, it may be necessary to reprogram the stimulator.

Existe otra alternativa terapéutica indicada en aquellos pacientes que presentan síntomas y signos eminentemente unilaterales de Parkinson de varios años de evolución, así como a aquellos en quienes por alguna razón específica no sea posible implantar un estimulador.

Esta técnica se denomina subtalamotomía y consiste en practicar una termolesión controlada en la zona motora del núcleo subtalámico causante de la sintomatología que presenta el paciente.

Where do we do it?

IN NAVARRA AND MADRID

The Department of Neurosurgery
at the Clínica Universidad de Navarra

The Neurosurgery Department has specialists with a great deal of experience in care and research and the most advanced technology.

We are the only Spanish center that incorporates high field intraoperative magnetic resonance (3T). This allows the maximum precision and control in cranial surgery.

We are the Spanish medical center with the most experience in Parkinson's surgery by means of deep brain stimulation. We have the latest technology with localized ultrasound (HIFU) and extensive experience in treating essential tremor and Parkinson's disease without an incision.
