Venous thromboembolism

Abstract

VTE is a significant cause of morbidity and mortality. It is the third most common cardiovascular condition worldwide following myocardial infarction and stroke. The 30-day mortality rates for patients with DVT and PE are 3% and 31 % respectively. VTE may be isolated (no identifiable cause) or may be secondary to a considerable number of conditions that lead to a hypercoagulable state. The clinical history and an understanding of the risk factors for VTE may point to an underlying cause. Conversely, knowledge of the predisposing factors may help detect subtle VTE and its complications on ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) studies. Multi modality imaging (US, CT and MRI) allows early detection of VTE and helps to identify its cause and any associated complications. It is also valuable to monitor the effects of treatment.
