Deep Vein Thrombosis (DVT) is a dangerous condition referring to blood clots in the deep veins, usually in the legs. There is a risk of the clot migrating to the lungs (known as Pulmonary Embolism) and also of severe leg swelling. Treatment requires blood-thinning tablets or injections for several months. Importantly, the cause of the DVT should be investigated also.
Sometimes when the clot is large and affecting leg function, a clot-dissolving procedure called Thrombolysis can be performed to re-open the veins and lower the chance of leg swelling and ulcers in the future. This decision needs to be made carefully on a patient by patient basis, and can be discussed during vascular surgery consultation. Occasionally a filter may need to be placed in the main vein of the abdomen, to prevent the clot from ascending to the lungs.
