The veins of the human vertebral canal have a complex internal structure that is stipulated with presence of a large amount of variable in form, size and position formations--plates, trabecules, complex and combined forms, parietal reticularity, cristae and valves. The data on peculiarities of macro-microconstruction of these structures, amount and their localization in various veins and parts of the vertebral canal are presented. Having analysed the data obtained, it is possible to divide the vertebral canal veins into three morphofunctional segments--superior (for the space of C1-C6), middle (C7-Th5) and inferior (Th6 and lower), possessing various hemodynamic characteristics Department of Human Anatomy, Medical Institute, Blagoveshchensk.

Neurofibromatosis is a genetic disorder arising de novo or with an autosomal dominant transmission that typically presents either at birth or in early childhood, manifesting through distinctive clinical features such as multiple café-au-lait spots, benign tumors in the skin, bone enlargement, and deformities. This literature review aims to resume the spectrum of maternal and fetal complications encountered in pregnant women with neurofibromatosis type 1 (NF1). Thorough research was conducted on databases such as Web of Science, PubMed, Science Direct, Google Scholar, and Wiley Online Library.

Anteriorly, the tumor widely invaded the mediastinum and displaced the aorta; on the left side, it expanded in the subpleuric region; posteriorly, it was uncommonly distant 13 mm from the posterior wall.

Background/objectives: Lumbar spinal stenosis (LSS) is a degenerative condition characterized by the narrowing of the spinal canal, resulting in chronic pain and impaired mobility. However, the molecular mechanisms underlying LSS remain unclear. In this study, we performed RNA sequencing (RNA-seq) to investigate differential gene expression in a rat LSS model and identify the key genes and pathways involved in its pathogenesis.

Objective: An MRI protocol for germinoma surveillance after complete remission has not been established. Moreover, the standard treatment for recurrent or refractory germinoma has not been determined. In this study, the authors explored the imaging characteristics of recurrent germinoma and discuss their institution's experience with multidisciplinary treatment of this malignancy.
