CHANGES IN THE FOREARM VESSELS OF PATIENTS WITH VIBRATION DISEASE AFTER CORONAVIRUS INFECTION

Abstract. A lot of scientific literature has already been written on the study of the consequences of a new coronavirus infection. The real long-term effects of this disease on population health are yet to be studied in the coming years. Vibration disease is a leading occupational pathology in the Russian Federation, characterized by vegetative-vascular disorders of the extremities and is manifested by cold extremities, cyanosis, paresthesias, and a violation of regional blood circulation. It is necessary to take into account the concomitant chronic diseases in patients who are particularly dangerous in the post-ovoid period. The aim of the study was to study the features of hemodynamics in patients with vibration disease after a new coronavirus infection. In the clinic of occupational pathology, 28 patients were examined with a previously established diagnosis of vibration disease after a coronavirus infection. Ultrasound examination of the arteries and veins of the upper extremities was performed. In patients with ultrasound of the vessels of the upper extremities, moderate expansion of the radial and ulnar veins, insufficiency of the valvular apparatus during functional tests, and increased venous outflow were revealed. There was also an increase in peripheral vascular resistance, which indicates violations of the tonic properties of the vessels of the upper extremities and violations of vasodilation. Inference. In patients with vibration disease in the post-ovoid period, ultrasound examination reveals violations of the tonic properties of blood vessels, venous dyscirculation in the veins of the forearm.
