[Pulmonary embolism following smoke inhalation].

Carbon monoxide poisoning is one of the most common types of intoxication and is linked to a high mortality rate when not managed appropriately. We are discussing the case of a patient found unconscious after a house fire, presenting a smoke inhalation injury and particularly carbon monoxide poisoning. The clinical course was marked by the development of a massive bilateral pulmonary embolism despite thromboprophylaxis. This case highlights the increased thromboembolic risk, which can persist up to 90 days after carbon monoxide poisoning. We analyse the cardiovascular manifestations while focusing on the thromboembolic risks. Finally, we provide a brief overview of the pathophysiology and management of this condition.
