In this review, the authors describe the new concept of MicroCLOTS (microvascular COVID-19 lung vessels obstructive thromboinflammatory syndrome) - proposed by Italian multidisciplinary team headed by Ciceri F, et al. as the cause of atypical acute respiratory distress syndrome. Ciceri F, et al. hypothesise that, in predisposed individuals, alveolar viral damage is followed by an inflammatory reaction and by microvascular pulmonary thrombosis. This progressive endothelial thromboinflammatory syndrome may also involve the microvascular bed of the brain and other vital organs, leading to multiple organ failure and death. In addition, patients with COVID-19 often develop macrovascular venous thrombosis as a result of the activation of the Virchow triad. Microvascular and macrovascular thrombosis development in patients with COVID-19 is confirmed by ultrasound examination of the veins of the lower extremities and complete autopsy study. The data obtained indicate the importance of the prevention of venous thrombosis with LMWH (nadroparin, enoxaparin) and Fondaparinux sodium in all hospitalized patients with COVID-19.
