Video Overview

Can deep vein thrombosis be life threatening? In order to answer this question, we must first understand what deep vein thrombosis is. The venous system in the legs is divided up into two systems: superficial veins and the deep veins. The superficial veins are what we see with varicose veins and spider veins. The deep veins are underneath the muscle. Deep vein thrombosis is a blood clot in the deep venous system. You cannot feel these or see theses but they can be very dangerous. Once blood clots form in the system, if they were to break off they would travel in the system up through your heart and to your lungs. They would get lodged in your lungs and this is called a pulmonary embolism. This prevents blood from getting into your lungs and can be a life threatening condition.
