Deep vein thrombosis is when a blood clot forms in one of the major veins deep inside the body. It most commonly occurs in the legs - lower leg, pelvis, or thigh. It can also occur in other parts of the body. Symptoms of deep vein thrombosis include leg or arm swelling, pain or soreness when standing or walking, enlarged veins, and skin that looks red or blue. To treat deep vein thrombosis, interventional radiologists perform thrombolysis, a thrombectomy or a filter or stent placement.
Varicose veins are twisted, swollen veins usually located in the legs. They are commonly caused by incompetent valves. When valves within veins are leaking, blood pools resulting in enlarged varicose or spider veins. Three interventional radiology procedures are performed to treat varicose veins including sclerotherapy, ambulatory phlebectomy and endovenous thermal ablation.
