OBJECTIVES: To report an unusual case of suicide attempt secondary complicated of pulmonary and systemic embolisms.
DATA SOURCE: A 49-year-old-woman, with a factor V Leiden mutation and a notion of chronic depression, admitted to our intensive care unit for a suicide attempt by ingestion ofmepronizine and lormetazepam.
DATA EXTRACTION: We report the rare evolution of this patient with a persistent alteration of consciousness associating a respiratory degradation. Despite the drug intoxication and possibility of aspiration, we performed a computed tomography (CT) angiography which confirmed the presence of a bilateral, proximal, pulmonary embolism suspected on transthoracic echocardiography. A cerebral CT showed left sylvian and cerebellar infarctions complicated of perilesional edema. Association of stroke and pulmonary embolism led us to suspect a patent foramen ovale (PFO). There was also a context of genetical perturbation of hemostasis. Transesophageal echocardiography confirmed the presence of a PFO undiagnosed by transthoracic echography. The PFO was complicated by an entrapped thrombus. The thrombotic complications were treated by unfractionated heparin.
DATA SYNTHESIS: Neurological and respiratory degradation following voluntary drug intoxication led to the discovery of both a pulmonary and cerebral embolism secondary to a PFO entrapped thrombus.
CONCLUSIONS: An entrapped thrombus in a PFO is a rare and dangerous situation, associated with many complications. Association of systemic and pulmonary embolisms should lead to PFO detection to guide therapeutic interventions.
