Minimally invasive neurosurgery

’First, do no harm’ is the principle that lead medicine towards minimally invasive approaches. The extraordinary technological advancement of the last decades fastened the development of all medical fields. Endoscopes, the high power surgical microscopes, neuronavigation, the extraordinary anaesthetic procedures allow safer and more precise surgical interventions. Minimally invasive neurosurgery or keyhole neurosurgery offers the patients the possibility to have surgery with minimal neurologic, medical, infectious and aesthetic risk.

Neuronavigation allows choosing the optimum approach with minimal tissue destruction from skin to the brain. The approach is tailored as the exposure of the brain is the minimal possible without altering the main goal of the surgery. The fast rehabilitation, the decrease of the perioperative stress and emotions, the avoidance of the need to shave the head are important advantages of the keyhole neurosurgery.

Our team is involved not only into the surgery of the patient, but also in all the other aspects of the necessary treatment like radiotherapy, chemotherapy, interventional radiology, rehabilitation etc. The optimal results are obtained when multidisciplinary meetings take place and the patient gets a plan of the treatment from the beginning. Every patient is unique, consequently the treatment needs to be optimised accordingly.

Minimally invasive techniques require the use of state-of-the-art technology. Operator endoscopes of various types, dedicated operator microscope, neuronavigation, neuroelectrophysiology, advanced anesthesia techniques, awake patient surgery represent an armamentarium without which neurosurgery by “keyhole” would not be possible. Using the techniques above, we treat a broad spectrum of cranio-cerebral pathologies.

It is the most common primary cerebral tumor (which develops from cerebral tissue) in adults. It is classified by the World Health Organization as IV grade (the most aggressive type of tumor). Glioblastomas grow rapidly and infiltrate the neighboring brain tissue. Treatment involves a multidisciplinary approach including surgery, chemotherapy and radiotherapy.


Meningioma is a tumor that develops from the cerebral meninges (the membrane that surrounds the brain and spinal cord). Most meningiomas are benign (noncancerous) tumors, although rarely they can be malignant (cancerous). Some meningiomas do not necessarily require immediate treatment, so, depending on size, symptoms etc a meningioma can be followed up only.

Vestibular schwannoma (acoustic neurinoma)

Vestibular schwannoma (acoustic neurinoma) is a rare, benign tumor that usually grows slowly and develops from the vestibular nerve (balance) near the acoustic and the facial nerves. Because of the pressure on these structures, signs and symptoms such as hearing loss often accompanied by constant and persistent sound in the affected ear, balance problems, and rarely facial paresis, are incipient signs of tumor progression.

Cerebral aneurysms

Cerebral aneurysms are abnormal dilations of cerebral arteries, usually saccular, but may also be fusiform. A cerebral aneurysm may rupture, leading to a bleeding in the brain and most often around it. A ruptured aneurysm is a surgical emergency. Frequently, aneurysms are discovered during investigations for other health problems. In these cases, treatment is usually needed to avoid a future rupture that is life-threatening.


Hydrocephalus is a disease characterized by excessive accumulation of CSF inside the cranial cavity. The CSF is a fluid normally produced in organs within the brain and is mostly absorbed at the level of the meninges (a membrane that protects the brain and spinal cord) through its specialized organs. When there is an imbalance between production and resorption, hydrocephalus results.


Cavernomas are vascular malformations that can form anywhere in the body. In the brain and spinal cord they can cause problems due to their hemorrhagic and epileptogenic potential. As their name says (cavernous malformations), these lesions are not tumors in the true sense of the word, but vascular abnormalities that usually develop in intrauterine life. Bleeding is usually unpredictable. There are never-bleeding lesions or lesions that bleed frequently, thus increasing the risk of major neurological deficits.

Cerebral metastases

Cerebral metastases – are malignant tumors originating from another neoplasia of the organism. Their treatment is often a combination of surgery, radiotherapy and chemotherapy. Treatment needs to be adapted to each patient, the multidisciplinary meetings held in our clinic being the ideal approach for such a pathology.
