First robotic neurosurgery in Latin America is performed in Porto Alegre

On August 10, Hospital Moinhos de Vento, in Porto Alegre, performed the first robotic neurosurgery in Latin America.

The procedure was performed in a patient who had pain in the lumbar spine with expansion to the lower extremities and without success with previous clinical treatments.


The patient, a 65-year-old man, was operated on by the team of neurosurgeons Arthur Pereira Filha and Nelson Pereira Filha.

Hospital Moinhos de Vento was created in 1927 and is the only Brazilian hospital affiliated with Johns Hopkins Medicine International. It is also one of the six of excellence in Brazil, according to the Ministry of Health. In addition, the hospital was also considered one of the best in Brazil by Newsweek and América Economia magazines.

The procedure performed was lumbar spine arthrodesis, which consists of the implantation of pedicle screws to stabilize two or more unstable vertebrae of the spine. In doing so, the team used innovative technology: Brainlab’s Cirq robotic arm.

Brainlab is a German company focused on computer-assisted surgery. It is the only device approved for use by the National Health Surveillance Agency (Anvisa) and works together with Curve surgical navigation systems, from the same supplier.

The system ensures that the surgeon plans the procedure preoperatively, including the necessary incisions and implant trajectories to enhance the surgical outcome. During surgery, the robotic arm improves the flow accuracy of the surgery. This ensures that the millimeters of the previously planned trajectory are executed.

“Before the surgery begins, it is possible to precisely define the dimensions and positioning of the screws that will be implanted in the patient”, explains physician Arthur Pereira Filho.

Arthrodesis of the lumbar spine is a procedure that aims to repair fractures created by injuries or diseases (osteoporosis or oncological diseases), in addition to anomalies caused by tumors, degenerative diseases of the spine (joint wear, herniated disc), congenital diseases (such as scoliosis). ) and others. Implants can be performed in three types of surgery: conventional, navigated and robotic.

Computer-assisted navigation and robotic guidance systems are increasingly being used in spinal surgery around the world. Research proves that robotic screw placement achieves greater precision, less radiation exposure, and fewer complications.

“For about 15 years, Hospital Moinhos de Vento has been using the neuronavigator in surgeries. However, this is the first time that a surgical team has also used a robotic arm,” says Dr. Arthur. Cirq was approved by the Food and Drug Administration (FDA), the regulatory agency of the United States, in 2019. In that country, 3.6 million spine surgeries were registered between 2001 and 2010, with increasing prevalence each year.

Several researches verify the effectiveness of Brainlab’s robotic systems. In 2021, doctors at the University of Marburg, Germany, prepared an analysis published in the Journal of Clinical Medicine, showing the results of 13 surgeries to implant 70 screws with the Cirq robotic arm in 12 patients, aged 67 years, who had several diseases – spondylodiscitis, metastases, osteoporotic fracture and spinal canal stenosis.

The average time of implantation of each screw was between 6 and 8 minutes. The authors consider that there was no perioperative deficit, that is, the period between the decision to operate and the patient’s hospital discharge.

The CEO of Hospital Moinhos de Vento, Mohamed Parrini, highlighted that the recent visit to Germany was precisely to try out new technologies used in hospital institutions and this device was known during the trip.

“Medicine increasingly relies on these advances that directly reflect on better treatments and patient outcomes. The institution is aligned with this new reality and has invested in state-of-the-art equipment with the purpose of taking care of people”, he declared.

Vinicius Dessoy Maciel, President of Brainlab for Latin America, highlights that in addition to being the only hospital that has used this technology in the country to date, Moinhos de Vento is a health organization that brings together extremely favorable technological and human conditions for its adoption in the surgical routine.

“Hospital Moinhos de Vento is already a pioneer in robotic surgery, and this is another milestone for the institution in terms of innovation and technology for the benefit of patients. This will be a new step towards putting into practice a dream of the management and the medical team, which is to build a robotic center that encompasses procedures in several specialties”, comments Arthur Pereira Filho.

The Cirq robotic arm expands the technology park of Hospital Moinhos de Vento. The institution’s Robotic Surgery Center already has robotic solutions such as Rosa Knee and Da Vinci, which demonstrate excellence in performing procedures, in addition to safety and precision for the medical team and the patient.

Investments for Neurology

Hospital Moinhos de Vento invested R$7.6 million to acquire ZEISS KINEVO 900 equipment and the Brainlab Curve navigation service. The new instruments allow more effective results, as they facilitate the surgeon’s control, with a micro-inspection of the area and visualization by augmented reality.

This visualization service uses more than 100 new features and the devices will be used mainly in surgeries of tumors of the nervous system, but also in cases of brain aneurysms, arteriovenous malformations, brain biopsies, spinal arthrodesis and any other procedures that require microsurgical manipulations. or precise location of anatomical structures.

According to the head of the Neurology and Neurosurgery Service at Hospital Moinhos de Vento, Sheila Martins, the new technology is very important to offer the best experience to patients and also to guarantee cutting-edge tools to specialists.

“We are working to make the best in terms of innovation and resources available to physicians. We leave nothing to be desired in comparison with the best health centers in the world. The institution has excellent professionals and they have the opportunity to offer their patients the best outcomes, safety and quality in the performance of procedures”, informs the neurologist.

Investment in new technologies at Hospital Moinhos de Vento is a constant process. Recently, another R$ 10 million was invested in new endoscopy systems and devices, of the Elxeo model, which has CAD EYE Artificial Intelligence technology. In the last year, more than R$ 14 million were also invested in state-of-the-art magnetic resonance equipment.
