What is Venous Virchow’s

Thromboembolism (VTE)? Triad BLOOD FLOW

STASIS

Rudolf Virchow (1821-1902) is known
as the father of modern pathology.
Venous thromboembolism (VTE) is a condition in which a blood clot forms most often in the Virchow’s research and discoveries

Embolus bed rest and clotting was uncovered. Since a provoking 1944 JAMA article, the
Travels to Lungs evils of bed rest have been well documented, and early indications of VTE as an

the challenges of the 2020 global pandemic have once again brought coagulation
