Injection drug induced septic embolism—A growing concern

Septic pulmonary embolism is an obstruction of the pulmonary vasculature due to embolization of an infected thrombus. In many instances, the etiology is cardiac in origin, given the increased prevalence of intravenous drug users in the United States. This condition usually presents with fever, chest pain, dyspnea, and cough. In order to make the diagnosis, it is helpful to utilize tools like the modified Duke criteria when evaluating for infective endocarditis in the context of pulmonary emboli and septic shock. The gold standard method for establishing the diagnosis of this condition involves imaging modalities, including echocardiogram and computed tomography findings. This case report details a 36-year-old male with a history of drug abuse and hepatitis C, who was found to have an isolated vegetation on the pulmonic valve and septic pulmonary embolism. The patient experienced a rapidly deteriorating clinical course, however improved over the course of 2 weeks with supportive measures and appropriate antibiotic treatment. The purpose of this case report is to highlight the uncommon nature of pulmonary valve involvement in patients with infective endocarditis. Moreover, the goal of this report is to recognize the paralleled increase in septic pulmonary emboli with the rising incidence of patients using injectable opioids in the United States.
