[Efficiency and safety of minimally invasive approaches for microsurgical treatment of brain aneurysms].

Unlabelled: Background. Brain aneurysms are found in 1-2% of population and cause subarachnoid hemorrhage (SAH) in 80-85% of cases. In recent decades, the incidence of unruptured aneurysms has increased due to widespread availability of CT and MRI.

[Surgical approach to resection of vestibular schwannomas following stereotactic radiological treatment. Surgical outcomes and morphological changes in tumors after radiotherapy].

Introduction: Radiation therapy of small vestibular schwannomas is quite often used as an effective alternative to surgical treatment. At the same time, 2-10% of patients are detected with radioresistant tumors progressing to varying degrees, which is associated with continued tumor growth. In these cases, a decision on surgical resection or re-irradiation of the tumor is made depending on the neurological symptoms, patient's somatic status, and neuroimaging data.

Spontaneous Transformation of Vestibular Schwannoma into Malignant Peripheral Nerve Sheath Tumor.

Although radiosurgery-induced transformation of vestibular schwannoma (VS) into malignant peripheral nerve sheath tumor (MPNST) is being widely discussed, little attention is paid to the spontaneous transition of these tumors. Although the pathogenesis of this phenomenon remains uncertain, growing number of reported cases might call to notice them. We present a case of a 29-year-old woman who suffered right-sided hearing loss which remained untreated for 4.

[Intracranial neurenteric cysts: experience of the Burdenko Neurosurgical Institute in the XXIth century].

Unlabelled: We present a series of cases of a rare pathology, intracranial neuroenteric cysts, a review of the international literature, and the experience in treating this pathology.

Material And Methods: Seven patients with intracranial neuroenteric cysts underwent surgery at the Neurosurgical Institute in the period between 2000 and 2015.

Conclusion: The main and only technique for treatment of intracranial neurenteric cysts is their resection.

[A malignant peripheral nerve sheath tumor developed from the auditory nerve: a case report and a literature review].

We present a rare clinical case of a patient with a malignant peripheral nerve sheath tumor developed from the auditory nerve as well as a literature review, including 30 reported cases of this disease.

[Surgical treatment of acoustic neuromas (vestibular schwannomas)].

Clinical guidelines are topical systematically developed provisions designed to help the doctor make a decision about a treatment approach in certain clinical situations; they provide information on conducting diagnostic and screening tests, the amount of medical and surgical care, and other aspects of clinical practice. Vestibular schwannomas account for 8% of all intracranial lesions, up to 30% of posterior cranial fossa tumors, and 85% of cerebellopontine angle tumors. The incidence rate of acoustic neuromas is approximately 1 case per 100000 population per year.

Use of surgical approaches to the posterior cranial fossa in patients in a lying position.

Background: Various suboccipital approaches are extensively used in modern neurosurgery for treatment of posterior cranial fossa disease. The main patient's positions on the operating table during surgery are half-sitting and lying ones.

Material And Methods: The article provides a detailed description and methodology of retrosigmoid suboccipital and median suboccipital approaches in a lying position.

[A technique of TachoComb application in dura mater reconstruction in surgery for posterior cranial fossa tumors].

Introduction: Liquorrhea is a condition characterized by cerebrospinal fluid (CSF) leakage from the cranial cavity due to injury to the integrity of the dura mater (DM) and bone structures of the skull base. Surgery for posterior cranial fossa (PCF) lesions distinguishes wound CSF leakage when CSF leaks from a surgical wound as well as basal CSF leakage (nasal liquorrhea and, less often, otoliquorrhea). The main cause of basal CSF leakage is injury (including surgical injury) resulting in a defect in the DM and bone structures (cells of the mastoid process in the case of a suboccipital retrosigmoid approach).

Cardiac arrest after induction of anesthesia in neurosurgical patients.

The paper reports two clinical cases observed with a time lag of four years. In both cases, there were severe clinical symptoms of intracranial hypertension before the surgery. Prompt full-scale resuscitation was required in both cases due to asystole that developed immediately after induction of anesthesia and tracheal intubation.

[Surgical treatment of trigeminal neuralgia in patients with multiple sclerosis].

Objective: Trigeminal neuralgia occurs in 1-7% patients with multiple sclerosis (MS). We assessed the efficacy of microvascular decompression of the trigeminal nerve in MS patients.

Material And Methods: We studied MS patients with trigeminal neuralgia who underwent microvascular decompression of the trigeminal nerve.
