Deep Vein Thrombosis News and Research

RSS

Deep vein thrombosis, or DVT, is a blood clot that forms in a vein deep in the body. Most deep vein clots occur in the lower leg or thigh. If the vein swells, the condition is called thrombophlebitis. A deep vein thrombosis can break loose and cause a serious problem in the lung, called a pulmonary embolism, or a heart attack or stroke.

Incidence of venous thromboembolism following COVID-19 vaccination

Researchers investigated the association between genetic predisposition to venous thromboembolism and increased risk of thrombosis post-COVID-19 vaccination.

Cancer patients with non-O blood types face higher risk of developing blood clots

A new Blood Advances study suggests that people with cancer and non-O blood types, such as types A, B, and AB, face an increased risk of developing venous thromboembolism (VTE), or blood clots in the veins, three months after their initial diagnosis.

Study finds higher risk of thrombotic events after SARS-CoV-2 infection

A study from Sweden published by The BMJ today finds an increased risk of deep vein thrombosis (a blood clot in the leg) up to three months after covid-19 infection, pulmonary embolism (a blood clot in the lung) up to six months, and a bleeding event up to two months.

The effects of severe COVID-19 on the lungs after one year

While short-term lung damage has been reported in patients hospitalized with pneumonia caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is little data on the more chronic sequelae of this condition. A new research paper summarizes data from patients seen one year from discharge.

Compared to influenza, COVID-19 is more likely to cause venous thrombosis

New research published in the medRxiv* preprint server suggests that COVID-19 illness incurs a greater 90-day risk of venous thrombosis than the flu. However, arterial thrombosis remains a higher risk among people with the influenza virus.

New AI algorithm may quickly, effectively diagnose deep vein thrombosis

A team of researchers are developing the use of an artificial intelligence (AI) algorithm with the aim of diagnosing deep vein thrombosis (DVT) more quickly and as effectively as traditional radiologist-interpreted diagnostic scans, potentially cutting down long patient waiting lists and avoiding patients unnecessarily receiving drugs to treat DVT when they don't have it.

Large Israeli study offers detailed look at safety profile of mRNA vaccine against SARS-CoV-2

A deep look into a nationwide mass vaccination setting in Israel revealed that the BNT162b2 (Pfizer–BioNTech) vaccine is not linked with an elevated risk of a majority of the adverse events under study, with the exception of myocarditis. However, even that potentially severe adverse event is much more pervasive following the infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), found a new study published in the New England Journal of Medicine (NEJM).
