BackgroundThe incidence of deep vein thrombosis (DVT) in CoViD-19 patients in intensive care units (ICU) has so far been investigated in only a few studies. Prospective comparative studies with non-CoViD-19 ICU patients are completely lacking.ObjectiveEvaluation of the incidence of DVT in ICU patients with CoViD-19 compared to non-CoViD-19 ICU patients who were treated in the University Hospital Augsburg during the same period. In addition, the aim was to investigate what type of anticoagulation was present in CoViD-19 patients at the time the DVT occurred and to what extent DVT is associated with increased mortality in this patient population.Material And MethodsIn this prospective single center study, which was conducted between 18 April 2020 and 30 April 2020, 20 SARS-CoV2 positive patients were compared with 20 non-CoVid-19 patients in the ICU with respect to the occurrence of DVT. For this purpose, demographic data, laboratory parameters, and clinical outcomes were recorded and evaluated.ResultsThe rate of DVT in the investigated patient collective was markedly higher in patients with SARS-CoV2 (CoViD-19 patients 20% vs. non-CoViD-19 patients 5%). Both DVT and elevated D‑dimer levels were associated with increased mortality in the present study.ConclusionWe recommend the determination of D‑dimer levels and, in the case of elevated levels, the broad indication for compression sonography of the deep leg veins on admission of patients with suspected or confirmed SARS-CoV2. In this way DVT in the setting of CoViD-19 can be recognized early and therapeutic anticoagulation can be started. All inpatient CoViD-19 patients should receive thrombosis prophylaxis with low molecular weight heparin. Further studies on point of care methods (TEG®, ROTEM®) for the detection of hypercoagulability in SARS-CoV2 are necessary.
