What are blood clots? When a blood vessel is injured, the cells of your blood bond together to form a blood clot. The blood clot helps you stop bleeding. Blood clots are good when they help seal a cut to stop bleeding. But sometimes, a blood clot can form when it is not needed. This type of blood clot can cause health problems or even death. Deep vein thrombosis (throm-BO-sis), or DVT, is a blood clot that forms in a vein deep in the body. DVT is the most common kind of blood clot people have after surgery for a hip or knee replacement. Most people who have one of these major surgeries are less active for several days or weeks after the surgery. This can cause blood flow to slow down, which increases the risk for a blood clot. People with a DVT may not have any symptoms and may not know they have one. As many as 4 people out of 10 who do not receive medicine to prevent blood clots develop a DVT within one or two weeks of having major hip or knee surgery. Taking medicine or using a device to prevent blood clots may lower the risk of developing a DVT after hip or knee surgery to 1 or 2 people out of 10. loose clot (embolus) blood clot 5
