What is the term for a blood clot that forms in a vein?

The term for a blood clot that forms in a vein is venous thrombosis. This condition occurs when blood flow in the veins is obstructed due to the formation of a clot, which can lead to various complications, including pain, swelling, and potential life-threatening conditions such as pulmonary embolism if the clot dislodges and travels to the lungs.

Understanding venous thrombosis is crucial, particularly in the context of vascular access, as patients with limited mobility or those who have had surgical procedures are at higher risk for developing this condition. It is important for healthcare practitioners to recognize the signs and symptoms of venous thrombosis and implement appropriate preventive measures, including the use of compression devices, mobilization protocols, and anticoagulant therapy when necessary.
