Endoscope

With the endoscope we can use a special fiber optic microcamera to see inside the tissues and direct special tools for biopsies and to investigate anatomical abnormalities, opening new drainage channels of the cerebrospinal fluid (eg 3rd ventriculostomy), opening of brain cysts , removal of pituitary tumours, removal of cerebral hematomas, and even the surgical treatment of aneurysms. Special training of neurosurgeons is required as far as the techniques of the endoscope are concerned. The more the progress and development of the equipment, the more neurosurgical diseases are treated with endoscopic methods, in combination with other techniques, such as neuronavigation.

Neuronavigation

Imagine a coordinate system similar to that of Earth, where every point on the patient’s skull and brain or spine is mapped.

Using modern computers, we direct with special precision the special tools in the affected area and perform operations such as biopsies or removal of tumors or placement of spinal fusion materials, without causing significant tissue injury. Neuronavigation has made it possible to remove brain tumors that were previously considered “unoperative”. Almost no damage or tumor is “impossible to remove”, thanks to the help of Neuronavigation. These surgeries are short and have almost zero risk of complications.

Thus, patients recover faster. With this technique we can also make targeted therapeutic interventions, administration of local pharmaceutical agents (chemotherapy, etc.) to ensure the maximum possible therapeutic effect.

Radiosurgery

 

 

This method can be used to treat many brain tumors (pituitary, acoustic neuromas, some metastases, as well as some vascular malformations, trigeminal neuralgia and other diseases. New techniques are being developed daily, relieving patients who can thus avoid open surgery, such as craniotomies, in selected cases.

Microsurgery

 

 

 

Just like other specialties, modern Neurosurgery often requires the use of a microscope to properly treat conditions such as slipped disk in the waist and neck, surgery for vascular lesions of the brain (aneurysms, vascular malformations, tumors), and spinal cord surgery. The use of a surgical microscope is now necessary in every neurosurgical unit and is combined with other infrastructures such as the endoscope, the neuronavigation and others. The use of the microscope in combination with percutaneous surgery, endoscopy and neuromonitoring, improves the effectiveness and safety of surgery. At the same time, blood loss, the risk of neurological damage, hospitalization time and recovery time after surgery are drastically reduced.

Spinal cord injuries

Spondylolisthesis, Spine Fractures

Percutaneous spinal fusion, immediate mobilization, without substantial post-operative pain

With the new technique of Minimally Invasive Spinal Surgery, fractures that need surgical stabilization become simpler and less painful. With very small incisions, similar to a laparoscopic operation, the necessary stabilization materials are placed, without substantial blood loss, and the patient is discharged in 2 days. Our experience shows that patients return to their activities pretty quickly, without any pain. Even the possibility of neurological damage caused by the injury is reduced, because these surgeries last less and the muscles, bones, and ligaments are not injured, so the recovery is faster.

Patients who have suffered a fracture or traumatic spondylolisthesis, either from a car accident, falling from a height, from osteoporosis or from a tumor of the spine , are suitable to undergo these surgeries. These surgeries are performed on the cervical, thoracic, and lumbar spine.

Our results are excellent, even in the most complex and “difficult” sort of speak cases, as shown in the following images from our cases:
