The paper presents the results of our own studies of the cerebral (arterial and venous) hemodynamic state with duplex scanning of the neck vessels, transcranial dopplerography of the cerebral vessels in patients with vertebro-basilar insufficiency. The study of venous blood flow characteristic of patients with venous encephalopathy revealed increased diameter of the internal jugular vein, increased blood flow rate and decreased pulsatility index of the basal Rosenthal vein, increased LVBF (linear velocity of blood flow) and diameter of the vertebral vein
Chronic venous hypertension (CVH) triggers a whole cascade of pathological reactions, the ultimate result of which is gross changes in the trophism of soft tissues of the lower extremities. The main hemodynamic factor leading to hypertension in the superficial venous system and, subsequently, to trophic changes in the lower limb, is blood reflux from deep veins, and it is associated with valve insufficiency at the mouth of the great and small saphenous veins (vertical reflux), as well as incompetency of perforators (horizontal reflux). Moreover, 90% of the latter are localized in the calf region, of which 87% belong to the veins of the Cockett I-III zone.
Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease primarily affecting the axial skeleton. Recent research has shed light on a concerning association between AS and venous thromboembolic disease (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism (PE). This paper explores the emerging evidence elucidating the heightened risk of VTE in patients with AS, emphasizing the underlying mechanisms and clinical implications. Factors such as chronic inflammation, endothelial dysfunction, and immobility contribute to the prothrombotic state observed in AS patients. Understanding this association is crucial for timely recognition, risk stratification, and implementation of preventive measures in clinical practice.
На протяжении многих лет, при изучении патогенеза заболеваний центральной нервной системы, венозной системе не придавалось большого значения. Отсутствие достоверных знаний, трудность постановки диагноза, а так-же отсутствие объективных методов изучения нарушения венозного кровообращения, не давало в полной мере исследовать влияние венозных нарушений на церебральную патологию [43, 44].
The article presents a clinical case of congenital arteriovenous dysplasia – Parkes Weber syndrome of the lower extremities. The features of its clinical picture and the difficulties of diagnosis are described. It is emphasized that Parkes Weber syndrome is a rare congenital disease of the vascular system, in some cases with the absence of its typical clinical manifestations and combined with other pathologies of the veins.
Rhodotorula species, part of the Basidiomycota phylum, is a typical ecological yeast that is found in air, soil, lakes, sea water, and natural product juice. colonize plants, people, and different vertebrates. The class Rhodotorula incorporates eight species, of which Rhodotorula mucilaginosa, Rhodotorula glutinis, and Rhodotorula minuta are human pathogens. It produces pink to red colonies and possess unicellular blastoconidia that lacks pseudohyphae and hyphae. Rhodotorula spp. have been perceived as arising yeast pathogen in humans over the most recent twenty years. While no instances of Rhodotorula disease were accounted for in the clinical writing before 1985, the cases expanded after that time, no doubt in light of the more extensive utilization of serious medicines and focal venous catheters.
Cardiovascular pathology and acute cerebrovascular accident (ACV) are in first and second place, respectively, as the causes of mortality in the structure of general mortality of the population. In this regard, interest in the issues of cerebral blood flow disorders does not weaken all over the world, more and more new aspects of this problem are being considered. CVA is a widespread pathology in the world and according to the WHO “... about 17.5 million people die every year from cerebrovascular diseases in the world, which is 30% of mortality from all diseases ...”. The most severe form of vascular pathology of the brain is a stroke. In European countries, mortality from stroke varies from 63.5 to 273.4 people per 100,000 population per year. About 85-88% of cerebral strokes are ischemic in nature. Ischemic stroke in developed countries ranks first as a cause of permanent disability. Movement disorders of varying severity are the most common and severe consequences of strokes.
Currently, the most effective method of treating chronic purulent middle otitis is tympanoplasty surgery. In our clinic, the introduction of laser radiation into the vein is used to improve the effectiveness of tympanoplasty. With the help of the method of irradiation of blood in the vein to the reparative processes of blood in the postoperative area, the increase in microcirculation of the mucous membrane under the influence of laser irradiation of blood was studied.
