Deep vein thrombosis

Other names: DVT


Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. DVT can cause leg pain or swelling, but may occur without any symptoms. It can be a serious condition as blood clots can break loose and travel to your lungs, causing a blockage known as Pulmonary embolism.



DVT occurs when a blood clot forms in deep veins, often due to conditions affecting blood clotting or prolonged immobility.


Various factors increase DVT risk, including genetics, prolonged bed rest, surgery, pregnancy, certain medications, obesity, smoking, cancer, heart failure, inflammatory bowel disease, age, and prolonged sitting.


The main complication of DVT is Pulmonary embolism. Postphlebitic syndrome can also occur post-DVT.


Gather information on symptoms and family history. Prepare questions for your doctor to maximize your appointment efficiency.


Diagnosis involves a physical exam and tests like ultrasound, blood tests, venography, and CT/MRI scans.


Treatment aims to prevent clot growth and Pulmonary embolism risk through blood thinners, clotbusters if severe, filters for some cases, and compression stockings.


Preventive measures include taking prescribed medications as directed, avoiding prolonged immobility, making lifestyle changes like weight loss and quitting smoking, and regular exercise.
