Risk Factors for Deep Venous Thrombosis among Patients Admitted to Vascular Unit

Abstract

eep venous thrombosis (DVT) is one of a major public health concerns and important leading cause of increasing morbidity and mortality worldwide; with an estimated annual incidence in developed countries 1 to 2 per 1,000 people each year and rates increase sharply after around age 45 years (Heit et al., 2018). Deep vein thrombosis DVT; refers to an obstruction of a deep vein by thrombus associated with inflammation of the vein, usually in the legs or pelvis but occasionally in the arms. DVT more likely to develop in the lower limbs in an estimated 60 per cent of cases; there is a higher incidence in the left leg than in the right (Kesieme, et al., 2018). DVT possible complications were divided into acute short term complication such as pulmonary embolism PE; which is the potentially life-threatening consequences of DVT and the major cause of mortality, which occurs when the thrombus formed in lower extremity travel to the lungs and obstructs a pulmonary artery, this known as venous thromboembolism (VTE). Morbidity of DVT due to long term complications that includes post-thrombotic syndrome (PTS); a disabling complication that reduces quality of life and is costly, causing chronic limb swelling pain, hyperpigmentation, heaviness and skin sores (Faustino et al., 2020).
