Multiple sclerosis (MS) is a common neurological disease, especially among people of young working age, and the number of MS cases registered in the world and in the Russian Federation tends to increase. The pathogenesis of MS is based on the theory of damage to its own myelin sheath as a result of activation of autoreactive T cells, which also leads to damage to both oligodendrocytes and axons. In addition, the role of vascular factor in the pathogenesis of MS is discussed in the literature periodically and several areas of research of vascular dysfunction in patients are identified. This article provides a retrospective analysis of the available literature dating from the 19th century to the present time in order to find the relationship between MS and changes in venous circulation.

Nutcracker syndrome (NCS) is an uncommon vascular condition caused by the compression of the left renal vein (LRN), which may result in venous hypertension and clinical symptoms, including hematuria, flank pain, and pelvic congestion. This report describes the case of a 30-year-old woman with recurrent painless macroscopic hematuria, ultimately diagnosed with NCS based on clinical and radiological findings. Computed tomography (CT) angiography revealed a reduced aortomesenteric angle and LRN compression without signs of severe venous hypertension or collateral circulation.

Severe accidental hypothermia can lead to cardiac arrest. The most efficient method of resuscitating and warming is by ECMO (Extracorporeal Membrane Oxygenation). While the convention is to use VA ECMO (Veno Arterial ECMO), using VV ECMO (Veno Venous ECMO) in which the blood is returned directly into the right ventricle could be an alternative and lead to conversion to life sustaining cardiac rhythm.

Background And Purpose: Prolonged venous transit (PVT), derived from computed tomography perfusion (CTP) time-to-maximum (T) maps, reflects compromised venous outflow (VO) in acute ischemic stroke due to large vessel occlusion (AIS-LVO). Poor VO is associated with worse clinical outcomes, but pre-treatment markers predictive of PVT are not well described.
Methods: We conducted a retrospective analysis of 189 patients with anterior circulation AIS-LVO who underwent baseline CT evaluation, including non-contrast CT, CT angiography, and CTP.

Background And Aims: The adipocyte-derived adiponectin (APN) has potent insulin-sensitizing and anti-inflammatory properties. The adipose tissue is known to be the main source for APN in the circulation, but sites and mechanisms which remove APN from blood are still unknown in humans.
Methods And Results: We reviewed APN data obtained in previous studies in which the inter-organ exchange of amino acids and cytokines was measured in our laboratory.

Background: V617F-mutated myeloproliferative neoplasms (MPN) exhibit abnormal proliferation of bone marrow progenitors and increased risk of thrombosis, specifically in splanchnic veins (SVT). The contribution of the endothelium to the development of the prothrombotic phenotype was explored.
Material And Methods: Plasma and serum samples from V617F MPN patients with (n=26) or without (n=7) thrombotic debut and different treatments, were obtained (n=33).
