[Arterial embolism, venous thrombosis, pulmonary embolism: a suggestive triad].

The aim of this study is to present a relatively rare case of paradoxical arterial embolism, found in a patient who was sent to us for serious pulmonary embolism. Taking into account that the foramen ovale, despite being functionally competent, remains anatomically patent in 30% of the adult population, we cannot neglect the possibility of a paradoxical embolism, in the presence of a sudden embolic limb ischemia unless heart pathology or aortic lesions can be held responsible. Furthermore it must not be forgotten that deep venous thrombosis in the lower limbs or in the pelvic plexus may go unobserved on a purely clinical evaluation.
