The lower-extremity venous system includes the superficial, deep, and perforating veins. Veins are composed of intimal, medial, and adventitial layers. The intimal layer rests on the basement membrane and produces many thrombogenic substances, including tissue plasminogen activator (tPA). The medial ...
Deep venous thrombosis (DVT) is the presence of coagulated blood, a thrombus, in one of the deep venous conduits that return blood to the heart. The clinical conundrum is that symptoms (pain and swelling) are often nonspecific or absent.

This placement can lead to thrombosis of the right iliac venous system. Endovascular treatment may be preferable when patients presenting with acute complications due to May-Thurner's syndrome are also pregnant.87,88 No randomized trials have been performed to compare endovenous stenting to open ...
tuberosity, collateral superficial veins present, diffuse leg swelling, localized tenderness along with the deep venous system, pitting edema which is greater in the symptomatic leg, paralysis or immobilization of lower extremity, and previous DVT. It gives minus 2 points if an alternate diagnosis is...
The Risk Factors for Pulmonary Embolism in Patients with Lower Extremity Deep Vein Thrombosis PURPOSE: Pulmonary embolism (PE) represents the most important and fatal complication of deep vein thrombosis (DVT), of which a dislodged thrombus is most commonly derived from the deep venous system of th...
The aim of this paper is to compare the accuracy of color Doppler to compression sonography in the diagnosis of lower extremity deep vein thrombosis. Longitudinal color flow imaging was performed in 60 lower extremities in patients with clinically suspected deep venous thrombosis (DVT). The study ...
