Chronic Complications of DVT

Deep Vein Thrombosis (DVT) is a known complication of varicose veins. Blood clots may form in varicose veins due to the sluggish blood flow in the abnormal vein.  Situations that increase the chance of developing a clot in a varicose vein include prolonged sitting during long distance travel, surgery or illness, dehydration or injury. Blood clot in a superficial vein or phlebitis can extend into the deep veins causing DVT. Once in the deep vein, the blood clot can cause significant pain and can damage the inside of the vein promoting more blood clot to form. Also, damage to the vein valves in the deep system can lead to Venous Hypertension, which is associated with leg swelling, leg pain and by definition, increased pressure in the leg veins overall. Prolonged effects of such increases in venous pressure affect the skin causing pigmentation, thickening of the tissues, and venous stasis ulceration. Subsequent failure of other leg vein valves extends the process more widely in the leg.  Treatment of DVT includes blood thinners, compression therapy, and leg elevation. Correction of varicose vein problems with VNUS Closure, phlebectomy or sclerotherapy may be appropriate after the DVT is stable.
