Dr. Federico Peralta

Dr. Federico Peralta is a consultant neurosurgeon at the British Hospital Buenos Aires — one of Argentina's oldest and most respected private hospitals, established in 1844 to serve the substantial British and English-speaking expatriate community in the Río de la Plata region. Today the hospital operates as a leading private tertiary care centre serving both Argentine patients and international visitors, with high standards aligned to the Joint Commission International (JCI) accreditation benchmarks.

With 15 years of neurosurgical experience, Dr. Peralta has developed a broad clinical practice encompassing brain tumour surgery, spinal neurosurgery, and the management of cerebrovascular conditions. He approaches every case with a commitment to maximising neurological function while achieving the safest possible surgical outcome — a philosophy that has led him to embrace minimally invasive techniques whenever they offer an advantage in terms of reduced tissue disruption, shorter hospitalisation, and faster recovery.

In brain tumour surgery, Dr. Peralta works closely with the hospital's neuroradiology and neuro-oncology teams to plan complex craniotomies using advanced preoperative imaging, including functional MRI and fibre-tracking tractography, to identify eloquent cortex and critical white matter pathways before surgery. Intraoperative neuromonitoring and awake craniotomy techniques are used when tumours involve speech, motor, or sensory areas.

In spine surgery, his practice covers degenerative conditions (herniated discs, spinal stenosis, spondylolisthesis), spinal tumours, and trauma. He uses minimally invasive percutaneous and tubular retractor systems to reduce surgical morbidity and accelerate recovery, particularly in older patients or those with significant medical comorbidities.

Dr. Peralta completed his medical degree at the Universidad Nacional de Córdoba — one of Argentina's oldest and most prestigious universities, with a strong medical school tradition. He undertook his Neurosurgery residency in Buenos Aires at a high-volume public neurosurgical centre, where he gained extensive experience across the full range of emergency and elective neurosurgical procedures during a demanding five-year training programme.

Following his residency, he pursued a clinical fellowship in Minimally Invasive Spine Surgery and Neuro-Oncology Surgery at a leading North American neurosurgical centre, where he was exposed to robotic spine surgery platforms, neuro-endoscopy, and advanced awake craniotomy techniques. He holds specialist certification in Neurosurgery from the Argentine Society of Neurosurgery (SAN) and is a member of the World Federation of Neurosurgical Societies (WFNS) and the Congress of Neurological Surgeons (CNS). He maintains his certification through ongoing professional development and regular attendance at national and international neurosurgical congresses.

Dr. Peralta's neurosurgical expertise spans intracranial and spinal domains. His intracranial practice is centred on brain tumour surgery — including resection of high-grade gliomas, low-grade gliomas, meningiomas, and brain metastases — using awake craniotomy, intraoperative ultrasound, and fluorescence-guided resection with 5-aminolevulinic acid (5-ALA) to maximise the extent of tumour removal while preserving neurological function. He also performs endoscopic endonasal surgery for pituitary adenomas and select skull base tumours, and has experience in stereotactic brain biopsy for lesions not amenable to open resection.

In the spine, Dr. Peralta performs minimally invasive microdiscectomy and laminectomy for radiculopathy and myelopathy, percutaneous pedicle screw fixation and transforaminal lumbar interbody fusion (TLIF) for spinal instability, and surgical treatment of spinal tumours. He also has experience in deep brain stimulation (DBS) for Parkinson's disease and essential tremor, working alongside neurologists in a multidisciplinary movement disorders programme.

For urgent neurosurgical conditions — including traumatic brain injury, acute subdural haematoma, and ruptured cerebral aneurysm — Dr. Peralta participates in the British Hospital's emergency neurosurgical on-call service.

Dr. Peralta's research interests are centred on improving outcomes in brain tumour surgery and minimally invasive spine procedures. He has contributed to clinical studies evaluating the impact of extent of resection on survival in high-grade glioma patients treated at Argentine neurosurgical centres, with findings presented at the Argentine Society of Neurosurgery's annual meeting.

He has also been involved in retrospective outcome analyses of minimally invasive lumbar spine surgery, documenting complication rates, hospital length of stay, and patient-reported outcomes in Argentine cohorts. His ongoing academic work focuses on the adoption and adaptation of advanced neuro-oncology surgical techniques — including fluorescence-guided resection and awake craniotomy — in the context of Argentine healthcare infrastructure.

Dr. Peralta conducts consultations in Spanish, English, and Italian, and is well-positioned to manage international neurosurgery patients at the British Hospital Buenos Aires, which has deep experience in serving non-Spanish-speaking patients given its historical mission. The hospital's international patient office provides coordination services for overseas patients seeking neurosurgical consultations.

For international patients seeking neurosurgical second opinions or treatment planning, Dr. Peralta offers video consultations to review MRI brain or spine studies, surgical reports, and oncology records. This allows him to provide a preliminary neurosurgical assessment and surgical plan before the patient travels to Buenos Aires. Post-operative follow-up, wound review, and neurological assessments can be partially managed remotely in collaboration with the patient's local neurologist or primary care physician.

Dr. Peralta holds specialist certification in Neurosurgery from the Argentine Society of Neurosurgery (SAN) and is a member of the World Federation of Neurosurgical Societies (WFNS) and the Congress of Neurological Surgeons (CNS). He has been recognised within the British Hospital Buenos Aires for his contributions to building the hospital's neurosurgical programme and for his dedication to adopting minimally invasive and technology-assisted surgical techniques that improve patient safety and recovery outcomes. He participates regularly in neurosurgical skills workshops and surgical simulation training, reflecting his belief that technical excellence requires continuous practice and learning.
