Trans-Magendie Foraminal Minimally Invasive Microsurgical Approach to the Fourth Ventricle and Brainstem: A Consecutive Series of 112 Cases

D I Pitskhelauri, A. N. Konovalov, Gleb Danilov, Andrey Bykanov et autres

Introduction: Among the currently described approaches to the fourth ventricle, the telovelar approach is the most frequently used. However, the telovelar approach has its drawbacks, which are associated mainly with excessive traction of the cerebellum and the frequent need to dissect the …

Transcranial motor evoked potentials in resection of supratentorial brain tumors adjacent to corticospinal tract in children

R A Kakhkharov, A A Ogurtsova, Sh U Kadyrov, Kristina Lapteva et autres

BACKGROUND: Transcranial motor evoked potentials (TMEPs) are one of the methods allowing functional preservation of motor pathways in resection of tumors adjacent to corticospinal tract. Studies of this method in pediatric neurosurgery note some difficulties in data interpretation, but most demonstrate high …

Continuous monitoring of somatosensory evoked potentials following spinothalamic tract stimulation in brainstem and spinal cord surgery: case report and literature review

Kristina Lapteva, Andrey Gavrjushin

BACKGROUND: The primary objective of neurosurgical intervention for central nervous system tumors is a balance between optimal tumor resection and minimal postoperative neurological impairment. Intraoperative neurophysiological monitoring is essential in safeguarding somatosensory tracts during surgery. Virtually the only tool for continuous monitoring …

Recovery of consciousness under therapy with benzodiazepines. A case report and literature review

Olga B. Belousova, Alexander Nikolaevich Konovalov, И. А. Савин, Т. M. Birg et autres

BACKGROUND: Treatment of patients with prolonged and permanent disturbance of consciousness is still an extremely difficult problem. Nowadays, management is based on pathophysiological and molecular mechanisms of impaired consciousness. Several electrophysiological and pharmacological methods were proposed to restore consciousness in appropriate patients. …

Status epilepticus after brain tumor surgery

Kristina Lapteva, И. А. Савин, Vadim N. Shimansky, M A Maslennikova et autres

BACKGROUND: Status epilepticus (SE) is characterized by continuous course of clinical and/or electrographic epileptic seizures. There are little data on the course and outcomes of SE after resection of brain tumors. OBJECTIVE: To analyze clinical and electrographic manifestations of SE, its course …

Corticobulbar motor evoked potentials in surgical treatment of tumors of the IV ventricle and brainstem

Kristina Lapteva, A A Ogurtsova, Yu. V. Strunina

BACKGROUND: Intraoperative neurophysiological monitoring is an obligatory tool during fossa posterior surgery. Corticobulbar motor evoked potentials is the modality of intraoperative neurophysiological monitoring, which can be used during such neurosurgery interventions. It is used to determine the functional state of the caudal …
