Treatment of the new coronavirus infection (NCVI) is associated with high risks of hemorrhagic complications. This is due to the use of anticoagulants to prevent coagulopathy and thrombotic complications, which are the most frequent and severe complications of NCVI.

The article presents the results of a retrospective analysis of 80 cases of spontaneous hematomas in patients with NCVI who were treated in a temporary infectious diseases hospital of the Republic of Clinical Hospital. Verification of the diagnosis was carried out using clinical data, ultrasound diagnostics, and computed tomography.

The mean age of the patients was 62.4 ± 14.47 years. The most common localizations of spontaneous hematoma were: abdominal wall — 31.3%, retroperitoneal hematoma — 26.3%, chest hematoma — 16.3%, lower or upper limb — 8.8%, neck — 3.8%, combined hematomas — 5%. The number of small hematomas was 87.5%, large – 12.5%. The highest incidence of spontaneous hematomas (74%) and mortality (22%) was recorded in the group of patients receiving therapeutic doses of anticoagulants.

X-ray endovascular diagnosis of the source of bleeding and its embolization was performed in 15 patients.

The use of therapeutic doses in patients with NCVI is accompanied by a high risk of developing spontaneous hematomas and, as a result, increases the risk of death. X-ray endovascular embolization of spontaneous hematomas is an effective and safe method of treatment in patients with NCVI.

Key words: COVID-19, NCVI, bleeding, anticoagulants, spontaneous hematoma.
