[Russian study on brain aneurysm surgery: a continuation (RIHA II)].

Objective: To assess the main performance indicators of neurosurgical departments in surgical treatment of cerebral aneurysms in the Russian Federation.

Material And Methods: We analyzed 22 neurosurgical departments (19 regional and 3 federal hospitals) in 2017 and 2021. The study enrolled 6.

[COVID-19-associated mucormycosis in ophthalmological practice in the Volgograd region].

The problem of fungal infections in the era of COVID-19 has acquired special significance. This infection, directly or indirectly, through the use of glucocorticoids and antibiotics in its treatment, as well as poorer self-management of chronic diseases, has led to a wide spread of risk factors for fungal diseases among people who have had a novel coronavirus infection. The article presents two cases of COVID-19-associated mycosis, more related to mucormycosis, which were diagnosed by ophthalmologists in the Volgograd region.

[Surgical treatment of cerebral aneurysms in the Russian Federation].

Objective: The objective of this study was to evaluate the results of surgical treatment of cerebral aneurysms in the Russian Federation.

Material And Methods: We analyzed performance indicators in neurosurgical departments of regional and federal health institutions of the Russian Federation for 2017. The results of surgical treatment of cerebral aneurysms (CAs) were analyzed in 19 regional vascular centers (RVCs) in several federal districts and in 3 federal centers (FCs) with the most dynamically developing vascular neurosurgery and smoothly running system of statistical data processing.

[Clinical-epidemiological analysis of a group of patients with surgically verified lumbar herniated discs].

Results of surgical treatment of 1085 patients with lumbar disc herniation operated from 1999 to 2009 were analyzed. It was shown, that frequency of LIII-IV and LIV-V herniated discs increases and that of LV-SI, decreases with ageing.

[Morphological rationale for medial facetectomy during microsurgical removal of herniated lumbar disks].

The study was undertaken to provide an anatomic and morphological rationale for the use of medial facetectomy in the microsurgical treatment of herniated lumbar disks and to assess the results of performed operations. Morphological studies were conducted on corpses, by comparing coronal and transverse sections of the lumbar spine. The concept "nervous root canal" was used during the study.
