Brain surgery


Neurosurgery is the medical specialty that is responsible for the management of diseases of the nervous system that require surgical treatment.

Much of this surgical activity is represented by cerebral neurosurgery, which addresses complex pathologies such as brain tumors, neurovascular problems such as cerebral aneurysms or arteriovenous malformations, cerebral hemorrhages, Chiari malformation, hydrocephalus, or pathology of pain such as trigeminal neuralgia.

Brain tumors

Brain tumors originate when a group of brain cells or other intracranial structures begins to grow independently and disorderly, forming a tumor or mass that induces a clinical symptomatology by compression of neighboring structures or by an increase of normal intracranial pressure. In many cases tumors are detected by performing imaging studies prescribed for other reasons.

Brain aneurysms are acquired dilations of the cerebral vessels in the form of a small balloon, which at a certain moment can be broken, causing severe cerebral hemorrhage. Neurosurgical treatment consists of excluding the aneurysm from the circulation by placing a small clip that closes the blood flow to it. If a good clip is achieved, this treatment is definitive.

Chiari malformation

The Chiari type I malformation, also known as Arnold-Chiari, is due to a compromise of space in the posterior cranial fossa, where vital structures such as the cerebellum and the brainstem are housed. In its natural evolution can cause neurological sequelae by involvement of structures of the spinal cord.

Trigeminal neuralgia

Trigeminal neuralgia manifests as an intense pain in the form of discharges that is usually distributed on one side of the face, most often in the areas of the cheek and jaw. The most favorable cases can be treated medically, but in cases with poor response to medication, the neurosurgeon should be consulted in order to evaluate the neurosurgical treatment of choice in these patients and obtain very satisfactory results.

When circulation of cerebrospinal fluid in the nervous system is hampered, there is a picture of hydrocephalus, which translates clinically with a decrease in the patient's level of consciousness, which can even reach coma. Hydrocephalus may manifest more severely in older adults as a form of cognitive impairment, which usually reverses after neurosurgical treatment.

How is brain surgery?

The neurosurgical treatment of the cerebral lesions is carried out by means of a craniotomy, technique by which the area where the tumor is reached through a window that we realize in the cranial bone.

The types of craniotomies are very varied depending on the type of injury we want to address, and contrary to what may seem, are generally interventions well tolerated by the patient and with a fairly comfortable postoperative, since it is usually only required in this period a conventional analgesia type acetaminophen, dexketoprofen or metamizole.

A very frequent question of the patients is: are they going to shave my head?

At Neurovist we perform the surgical wounds hidden in the hair and without shaving the head in any case, with this we get an excellent cosmetic result in all cases.

At the end of the intervention the patient is awakened in the operating room, and later, by protocol, he / she is transferred to the ICU where he / she stays for about 24 hours.

An early postoperative control test (cranial CT or brain magnetic resonance imaging) is performed and after its evaluation the patient is transferred to the plant, where he initiates the mobilization, and we advise him to wander around the room.

The hospital stay is variable depending on each patient and the type of intervention, the average is usually 3-4 days.

The first postoperative check in outpatient clinics is scheduled 15 days after surgery.
