Brief Summary:
The purpose of the study is to assess the frequency of the occurrence of a venous thrombosis in patients with the new Coronavirus disease, who are admitted to the Intensive Care Unit for impending respiratory failure requiring intubation and mechanical ventilation. Furthermore, the investigators aim at identifying potential risk factors for thrombosis and death.

Condition or disease Intervention/treatment
SARS Virus Other: Ultrasonography

Detailed Description:
Symptomatic infection with the severe acute respiratory syndrome coronavirus 2 ranges from mild to critical spectrum. About 80% of laboratory confirmed infections presented with mild symptoms, usually not requiring hospitalization. Critical disease requiring respiratory and/or circulatory support was reported in 5% of the subjects. Acute respiratory distress syndrome represents the most common complication in patients with severe disease. Several cases of venous thromboembolism in patients with laboratory confirmed infection have been reported, but it is unclear if this occurrence is higher in this specific patients' population. The purpose of the present study is to assess the prevalence of deep venous thrombosis in patients infected with SARS-CoV-2 admitted to the Intensive care Unit requiring invasive mechanical ventilation using vein ultrasonography.
