Deep vein thrombosis (DVT) (also known as deep venous thrombosis or economy class syndrome) is the formation of a blood clot ("thrombus") in a deep vein. It is a form of thrombophlebitis (inflammation of a vein with clot formation).
Deep vein thrombosis commonly affects the leg veins (such as the femoral vein or the popliteal vein) or the deep veins of the pelvis. Occasionally the veins of the arm are affected (if spontaneous, this is known as Paget-Schrötter disease). A DVT can occur without symptoms, but in many cases the affected extremity will be painful, swollen, red, and warm, and the superficial veins may be engorged. The most serious complication of a DVT is that the clot could dislodge and travel to the lungs, which is called a pulmonary embolism (PE). DVT is a medical emergency, so, all limb swellings, however trivial, should be regarded as a DVT until proven otherwise. Untreated lower extremity DVT has a 3% PE-related mortality rate. Deaths associated with upper extremity DVT are extremely rare.[1] A late complication of DVT is the post-thrombotic syndrome, which can manifest itself as edema, pain or discomfort and skin problems.
