Successful surgical treatment for a thrombus straddling a patent foramen ovale: a case report

Abstract

Paradoxical embolism (PDE) occurs after embolic material passes from the venous to the arterial circulation through a right-to-left shunt, which is frequently a patent foramen ovale (PFO). We describe the case of a patient with deep venous thrombosis and an intracardiac thrombus straddling a PFO and who was successfully treated with an emergency surgery.

Concomitant Pulmonary and Cerebral Tumor Embolism and Intracardiac Metastasis from Bladder Cancer

“…Some strokes of unknown origin may be caused by paradoxical embolism due to PFO (1). Although observing a thrombus straddling the PFO is difficult, some cases are detected by echocardiography (6)(7)(8)(9)(10)(11). In the present case, we considered there to be a high possibility of tumor embolism rather than thromboembolism, including Trousseau syndrome.…”

Thrombus straddling a patent foramen ovale, pulmonary embolism and paradoxical embolism: a rare trifecta

“…Passage of an embolus through a PFO is far more common than a TSPFO. TSPFO may be associated with a pulmonary embolism (94%) or, less commonly, a PDE (44%) 2. In the presence of massive PE, the risk of PDE increases due to the transient increase in right atrial pressure 3.…”
