[Computed tomography and endovascular occlusion in diagnosis and treatment of spontaneous bleeding into soft tissues of abdominal, chest wall and retroperitoneal space in patients with COVID-19].

Angiography confirmed MR signs of contrast agent extravasation in 34.3% of patients. In case of extravasation in all CT phases, ongoing bleeding was confirmed in 66.7% of patients. Endovascular embolization is effective for arterial bleeding into soft tissues. However, large-scale studies are needed to assess the effect of this technique on survival.
