Paradoxical peripheral embolism coincident with acute pulmonary thromboembolism

Paradoxical embolism may occur in patients with acute pulmonary thromboembolism, when patent foramen ovale (PFO) coexists with pulmonary hypertension (right-left shunt). There have been few case reports of paradoxical embolism in peripheral arteries coincident with acute pulmonary thromboembolism. Here, we describe a case of paradoxical peripheral embolism associated with PFO complicated by acute pulmonary thromboembolism. The patient had severe peripheral ischemia due to a massive thrombus and was treated successfully by peripheral thrombectomy, thrombolysis, implantation of a permanent inferior vena cava filter and anticoagulation.
