Abstract Pulmonary embolism results from an emboli in any part of the pulmonary circulation, it is usually caused by avenous thrombosis in the deep veins, Risk factors for pulmonary embolism include three basic forms called Virchow triad: Vascular trauma, Increased coagulability, Reduced blood flow, The clinical manifestations of pulmonary embolism are nonspecific, but their presence with one of the risk factors leads to pulmonary embolism, and then we carry out appropriate investigations and measures, Plain chest X-ray is often non directional and is used to ruleout symptoms clinically similar to pulmonary embolus, Pulmonary angiography is currently considered the gold standard for diagnosis, It is often performed using the multishider technique, wich has asensitivity and specificity equal to contrast angiography, but it is a non – invasive procedure and is therefore more widely used
