Report of the third international Siberian neurosurgical conference (Sibneuro 22): Scientific and professional exchange in the heart of Siberia.

We present a summary of the recently held Third International Siberian Neurosurgical Conference (Sibneuro 22). Professional education, scientific exchange, and social interactions are essential in neurosurgical practice. In addition to the main program of the Congress, there were two practical pre-meeting courses: on aneurysm clipping and on intraoperative neuromonitoring. In addition, there was a 1-day seminar focusing on a role of laboratory diagnostics in neurosurgical practice. Within the framework of the Siberian Congress, there was a session devoted to inventions in neurosurgery, a rare subject of discussion at neurosurgical events. Our educational event is very important for the Siberian neurosurgery. Neurosurgeons of Siberia are a part of the world neurosurgical family. We not only try providing high-quality neurosurgical care to patients but also maintaining the academic level of education and scientific activity. The next - fourth - Siberian Neurosurgical Congress will take place in July 2024 in Irkutsk.

CLINICAL AND IMAGING FEATURES OF MEDIAL MEDULLARY INFARCTION: RESULTS OF A PROSPECTIVE HOSPITAL-BASED COHORT STUDY ILLUSTRATED WITH A CASE REPORT IN A WHITE EUROPEAN ADULT.

OBJECTIVE: The aim: This study aims in a prospective hospital-based cohort study to determine clinical and imaging features of medial medullary infarction and report a relevant clinical case in a white European adult. PATIENTS AND METHODS: Materials and methods: We have prospectively enrolled one hundred twenty adult patients with acute posterior circulation stroke. All patients were admitted and enrolled in the study within 6 to 24 hours from the onset of the stroke symptoms. Study subjects were recruited from the hospital's wards and emergency departments from 2011 to 2020. Comprehensive clinical, MRI, ultrasound, and laboratory examinations were performed on all patients. RESULTS: Results: 68 men and 52 women aged 28 to 89 years (average age 60.7 ± 12.1 years) with an acute ischemic posterior circulation stroke were enrolled in the study. Out of these 120 patients, 22 (18.3%) had acute medulla oblongata infarctions. Clinical and imaging features of medial medullary infarction are analyzed and illustrated with a clinical case presentation in a white European adult. CONCLUSION: Conclusions: Specific features of medial medullary infarction were determined, analyzed, described, and illustrated with a clinical case.

MULTIPLE ACUTE POSTERIOR CIRCULATION STROKE WITH LESIONS IN THE PONS AND BOTH HEMISPHERES OF THE CEREBELLUM ASSOCIATED WITH OVARIAN HYPERSTIMULATION SYNDROME: A CASE REPORT OF A WHITE EUROPEAN ADULT IN UKRAINE.

We have presented a brief literature overview of the disease, supported by a clinical case of multiple acute posterior circulation strokes with lesions in the pons and both hemispheres of the cerebellum associated with ovarian hyperstimulation syndrome in a white young European adult in Ukraine. Specific features of posterior circulation stroke associated with ovarian hyperstimulation syndrome were determined, analyzed, and described. Complex posterior circulation cerebral infarction in the pons and both hemispheres of the cerebellum associated with ovarian hyperstimulation syndrome has not been reported before but has devastating consequences for both mother and fetus. Strokes in patients with OHSS must be timely prevented, promptly diagnosed, and treated to avoid high morbidity and mortality associated with it.
