Pulmonary embolism is an entity of venous thromboembolic disease. It is due to the obstruction of the pulmonary artery or one of its branches by a blood clot that has most often migrated from a vein of the lower limbs. It is a therapeutic emergency because it involves the prognosis of patients because of respiratory and hemodynamic complications. Its management is essentially a diagnostic challenge for the clinician because the clinical symptoms of pulmonary embolism are not specific. Similarly, the required additional tests cannot provide diagnostic certainty and must be integrated into a strategy based on the initial clinical probability. Our study includes 40 patients admitted for management of pulmonary embolism confirmed , during the period between January 2010 and December 2014. We tried through this work to answer the following questions:- What is the plot of occurrence of pulmonary embolism?- What is the clinical symptomatology of admission?- What is the diagnostic strategy adopted using the modified Geneva score?- What is the therapeutic strategy?- What is the hospital evolution?The diagnostic strategy of pulmonary embolism should be based on a codified decision algorithm taking admission of the patient. The treatment, antithrombotic essentially, depends on the patient’s hemodynamic status. The evaluation of the management of this cardiovascular emergency in a Moroccan population is essential for the development of local protocols adapted to our daily practice
