Deep Vein Thrombosis Causes and Risks

Deep vein thrombosis (DVT) occurs when a blood clot forms in a vein deep inside a muscle in your body. It usually happens in legs, but can also develop in your arms, chest, or other areas of your body. And though DVT is not common, it can be dangerous. The blood clot can block your circulation or lodge in a blood vessel in your lungs, heart, or other area. The clot can cause severe organ damage and even death -- within hours.
