Deep vein thrombosis (DVT) is a serious condition that is caused when a blood clot forms in a deep vein found in the legs and occasionally in the arms. If left untreated, the blood clot can travel through the bloodstream into the lungs, causing circulation to be interrupted. Our interventional radiologists can use ultrasound to measure the blood flow through the veins to find any clots, determine if a blood clot is growing, or make sure a new one has not developed. Most patients can resume their normal activity the day of discharge from the hospital. Procedures include diagnostic venography, mechanical/aspiration thrombectomy, intravascular ultrasound, and venous stenting. Surgical thrombectomy is used in cases of VTE involving limb or life threatening emergencies such as massive pulmonary embolism, and is not routinely used for lower extremity DVT treatment.
