Welcome to Nevron, the neurosurgical team of internationally recognized specialists. Our vision is to provide coordinated therapeutic approaches tailored to the unique needs of each patient, across the full spectrum of brain, spinal, and peripheral nerve disorders, as well as chronic pain.
The two main contributors to this initiative are Prof. Stavrinou and Prof. Chaliasos, with a combined experience of over 30 years in leading academic institutions and hospitals abroad (University Clinic of Cologne and Queen Mary University of London).
The right patient, the right treatment, with maximum safety
The team is further supported by attending physicians providing 24/7, year-round coverage, along with a dedicated nurse, while continuous support is available from a physiotherapist, speech therapist, neuropsychologist, and intensive care unit.
As an innovation in the Greek healthcare landscape, the advanced nurse practitioner plays a pivotal role in assisting patients from the moment they arrive at the center through the months following their treatment, ensuring continuous guidance and support for any concerns—both preoperatively and postoperatively.
Goals
The goals set by the two neurosurgeons for the next five years are:
- Selection of treatments from the full range of international protocols, with the collaboration of all team members.
- Weekly scientific meetings where demanding clinical cases are discussed between the two expert neurosurgeons.
- Minimally invasive and non-invasive treatment methods, enabling patients to return to their daily lives as quickly as possible.
- Maximizing safety and reducing complications—the two directors review and complement each other’s work daily to prevent errors.
- Utilization of the most advanced medical technologies, such as AI-assisted robotic systems and minimally invasive techniques.
- Monthly measurable success outcomes and quality control of every medical procedure.
- Fully digitized patient records.
The center’s standards are aligned with leading institutions in the United States and Europe. A significant investment has been made in cutting-edge technologies.
Cutting-Edge Technologies
Robotic Exoscope 4K 3D
Unparalleled imaging and detail during surgery, enabling the surgeon to safely access all regions of the brain and spine.
The exoscope is a revolutionary new tool in neurosurgery, offering significant advantages in visualization and execution of procedures within the central nervous system. Below are some of its key features:
- Three-Dimensional Imaging: Provides high-quality 3D images, allowing surgeons to observe the brain’s anatomical structures in exceptional detail.
- Adjustable Viewing Angle: The exoscope can modify the viewing angle, enabling surgeons to examine surgical areas more quickly and with greater ease.
- Ergonomics: Compared to the traditional microscope, the exoscope allows surgeons to operate in more comfortable positions, reducing fatigue during lengthy procedures.
- Time Efficiency: Its rapid and simple adjustments shorten surgical duration, as surgeons spend less time on repositioning and technical settings.
- Technology Integration: Offers imaging support and features such as video integration, enhancing both surgical team communication and medical training.
Intraoperative CT O-ARM and Intraoperative Ultrasound iUSS
By combining both systems, the two surgeons gain real-time imaging of the surgical field during the procedure. The advantages include:
- Smaller incisions, since the exact area of interest can be targeted directly
- Avoidance of blood vessels and other high-risk structures
- Complete tumor removal with real-time verification during surgery
- Precise electrode placement during DBS (Deep Brain Stimulation) and pain management interventions

Intraoperative CT O-ARM
Robotic Arm for Brain Biopsies
Advantages:
- High Accuracy: Provides precise guidance during biopsies, minimizing the risk of injury to surrounding tissues and structures.
- Reduced Surgical Time: Use of the robotic system can shorten procedures, allowing for faster completion.
- Less Pain and Faster Recovery: Minimally invasive techniques mean patients may experience less discomfort and quicker recovery.
- Enhanced Imaging and Planning: Advanced imaging technologies offer improved visualization of targets, enabling better surgical planning.
- Stability and Reliability: The robotic arm ensures steady performance, reducing the chances of errors due to human factors.
- Ease of Use: Surgeons can operate the robotic arm with greater control and accuracy, improving procedural efficiency.
- Capability for Multiple Biopsies: Facilitates repeat biopsies at different locations without requiring large incisions.

Robotic Arm for Stereotactic Procedures

Neuronavigation & Intraoperative Ultrasound
iMRI
Expertise in the use of intraoperative MRI during functional neurosurgery and tumor resections ensures that the desired outcome is achieved before the surgery is completed. Key advantages include:
- Enhanced Accuracy and Real-Time Effectiveness: Provides surgeons with immediate brain imaging during surgery, ensuring precise assessment of anatomical structures and the extent of tumor removal. Imaging can be performed after each surgical step, allowing instant evaluation and adjustment of the surgical strategy.
- Increased Safety: Reduces the risk of complications, as surgeons can verify whether tumors have been completely removed or if remnants remain in critical areas.
- Minimization of Repeat Surgeries: With real-time evaluation, the likelihood of needing a second procedure is significantly reduced.
- Personalized Surgical Strategy: Continuous adjustments can be made intraoperatively, based on the imaging data obtained from iMRI.

Intraoperative MRI Capability for Brain Tumor Surgery
Laser visualase
Designed for minimally invasive tumor removal and epilepsy treatment with an incision of less than 12 mm. Visualase is an advanced interventional system that combines computer-assisted imaging and laser technology to precisely target and ablate cancerous tumors and other pathological tissues.

Laser Tumor Ablation with Real-Time MRI Monitoring
Key Features and Advantages:
- Minimally Invasive Approach: Visualase enables tumor removal with minimal invasiveness, reducing damage to surrounding tissues.
- Computer-Assisted Imaging: Utilizes 3D representations and advanced computational techniques for accurate tumor localization, providing surgeons with a clearer anatomical view.
- Real-Time Procedure Monitoring: Offers continuous monitoring during the procedure, allowing immediate adjustments to the surgical approach.
- Reduced Bleeding and Pain: Minimizes intraoperative bleeding and postoperative pain, leading to faster patient recovery.
- Improved Outcomes: Patients often experience better results and fewer complications compared to traditional surgical methods.
Deep Brain Stimulation (DBS) and Spinal Cord Stimulation
Treatment of movement disorders (Parkinson’s disease, tremor, dystonia) and chronic pain. Through the Metropolitan Hospital, the Nevron team now constitutes the largest DBS center in Greece, performing 70% of all national cases. The procedure involves implanting electrodes in specific brain regions, which are connected to a small pulse generator placed under the skin in the chest. DBS is also applied to several neurological and psychiatric disorders, such as depression and obsessive-compulsive disorder, showing promise for further research.

Minimally Invasive Treatment of Spinal Disorders
The most common spinal conditions—such as disc herniation, stenosis, and spondylolisthesis—are treated through very small incisions or endoscopically, often with the aid of neuronavigation. This results in less postoperative pain, minimal blood loss, quicker return to daily activities, and a lower complication rate.
Cryotherapy, Laser, Radiofrequency, and Spinal Cord Neuromodulation Techniques
These methods are applied for the treatment of chronic, treatment-resistant neck and back pain. The therapeutic approach is decided by a multidisciplinary scientific board (interventional pain management team) that includes a radiologist, a pain specialist anesthesiologist, and our neurosurgical team.

Spinal Cord Stimulator for Chronic Pain Patients
Intraoperative Neurophysiological Monitoring
The use of electrophysiological techniques to monitor the functional integrity of nerves during surgery. The purpose of neuromonitoring is to reduce the risk of neurological injury and to provide real-time functional guidance to both the surgeon and the anesthesiologist.
