Deep vein thrombosis, or deep venous thrombosis, (DVT) is the formation of a blood clot (thrombus) within a deep vein, predominantly in the legs. Non-specific signs may include pain, swelling, redness, warmness, and engorged superficial veins. DVT often develops in the calf veins and "grows" in the direction of venous flow, towards the heart. When DVT does not grow; it can be cleared naturally and dissolved into the blood (fibrinolysis).
We studied 100 Israeli patients with BD, 66 Jews and 34 Arabs. There were no statistically significant differences between Jewish and Arab patients with respect to male: female ratio, prevalence of HLA-B5, age of disease onset, or disease duration. Disease expression and severity score were also similar in the 2 groups, but Arab patients had a higher rate of posterior uveitis (20.6 vs 4.6%; p < 0.03). Among the 3 largest Jewish ethnic groups, patients of North African origin had a significantly higher rate of ocular disease (p < 0.01), mainly in the form of anterior uveitis (p < 0.01).
The basic treatments for the disease are Anticoagulation, which prevents further coagulation, home treatment, stockings, walking, and repeat imaging and IVC filters, thrombolysis, and thrombectomy. The aims of the physicians are to prevent clot becoming larger, clot becoming lose and traveling to lungs, new clot formation and Post thrombotic syndrome.
Major Research on Disease
The current major research on the diseases are efficacy of low doses of heparin for the prevention of the DVT after a major surgery, accuracy of the clinical assessment for DVT, Decreased plasma levels of activated factor VII in patients with deep vein thrombosis etc.
