World Thrombosis Day

From Head to Toe, Take Control. World Thrombosis Day is a global campaign of the ISTH that raises awareness of thrombosis on Oct. 13.
(1)

Celebrated year round, World Thrombosis Day (WTD) is recognized on 13 October. WTD focuses attention on the often overlooked and misunderstood disease of thrombosis. With thousands of educational events in countries around the world, WTD and its partners place a global spotlight on thrombosis as an urgent and growing health problem. Bringing together communities around the world to , the quiet, underlying disorder that is the common mechanism of the world’s three top cardiovascular killers – heart attack, stroke and venous thromboembolism (VTE) – the International Society on Thrombosis and Haemostasis (ISTH) launched WTD in 2014. Partnering with thrombosis societies from every continent of the world, the ISTH teams up with continental cardiovascular, neurology and hematology organizations in the effort to educate the public, health care professionals and policy makers about thrombosis risks, prevention and treatment. More than 5,000 partners from every continent of the world have pledged their support to WTD, with more joining every day. For a list of those organizations and for those interested in making the pledge and joining the effort, visit www.worldthrombosisday.org. We invite you to participate!

🩺 Clot Classroom: Renal Vein Thrombosis (RVT). When a blood clot forms in the vein that drains blood from your kidney, it’s called renal vein thrombosis.

Think of it like a clogged pipe: when blood can’t flow out properly, your kidney can’t do its job of filtering and cleaning your blood.

💡 Did you know? In adults, RVT is often linked to nephrotic syndrome, where certain conditions can make the kidneys too “leaky.” Learning the signs helps you protect your health. Learn more here: bit.ly/4pUT7js
