Abstract
One-third of patients with symptomatic venous thromboembolism (VTE) manifest pulmonary embolism, whereas two-thirds manifest deep vein thrombosis (DVT). Overall, 25%-50% of patients with first-time VTE have an idiopathic condition, without a readily identifiable risk factor, and its association with tuberculosis (TB) is a rare occurrence. Deep venous thrombosis has been associated with 1.5%-3.4% cases of TB. Early initiation of anti-TB treatment along with anticoagulant therapy decreases the overall morbidity and mortality associated with the disease. We report three cases of DVT associated with pulmonary TB who were diagnosed due to high index of suspicion as the risk factors for the development of DVT were present in these cases.
