Deep venous thrombosis; DVT; Venous thromboembolism; VTE
Venous thrombosis occurs when a blood clot forms in a vein.
Venous stasis, vessel wall injury, and hypercoagulable state, collectively known as Virchow’s Triad, contribute to the development of venous thrombosis. Deep vein thrombosis (DVT) typically begins in the deep veins of the calf, and about 20% will propagate proximally. A small proportion of proximal DVTs may embolize to the pulmonary circulation or elsewhere, which, in some cases, can cause death from massive pulmonary embolism (PE). DVT is common in hospitalized patients, and incidence estimates are 30–90% among people with recent stroke. DVT is associated with many other conditions that limit mobility or increase hypercoaguability, including spinal cord injury, traumatic brain injury, cancer, and prolonged bedrest for other illnesses. Recent research has demonstrated the effectiveness of prophylactic anticoagulation and mobilization...
