1/88. Patent foramen ovale as a potential cause of paradoxical embolism in the postpartum period.

    We report a case of previously healthy woman who suffered cerebral embolism after delivery. echocardiography with contrast medium confirmed the patent foramen ovale (PFO). PFO may be a mechanism of paradoxical embolism causing a transient ischemic attack or stroke.

2/88. Cerebral embolism after mechanical thrombolysis of a clotted hemodialysis access.

    Clinically significant embolic complications after thrombolysis of clotted hemodialysis grafts are uncommon. Most of the concern has focused on the risks associated with pulmonary emboli. We report a case of a hemodialysis patient who developed a cerebral embolism after percutaneous graft thrombolysis who was found to have a patent foramen ovale and intermittent right-to-left shunt.

3/88. Bilateral renal infarction secondary to paradoxical embolism.

    Paradoxical embolism is an uncommon but increasingly reported cause of arterial embolic events. Involvement of the kidney is rarely reported. autopsy studies suggest, however, that embolic renal infarction is underdiagnosed antemortem. We report a case of bilateral, main renal artery occlusion and acute renal failure secondary to paradoxical embolism. Clinical and laboratory data at presentation were not suggestive of renal infarction. Support for the diagnosis of paradoxical embolism, which most commonly occurs across a patent foramen ovale, was made by contrast echocardiography, which provides a sensitive method for detecting right-to-left intracardiac shunts. The often subtle presentation of renal infarction suggests patients with peripheral or central arterial embolic events should be carefully observed for occult renal involvement. Contrast echocardiography should be performed when renal infarction occurs without a clear embolic source to evaluate for paradoxical embolism.

4/88. Paradoxical embolism in a boy with cystic fibrosis and a stroke.

    An 11 year old boy with cystic fibrosis suffered a stroke, producing right sided weakness. Four years previously a totally implantable venous access device (Port-a-Cath) had been inserted. magnetic resonance angiography revealed a filling defect in the left middle cerebral artery. Transoesophageal echocardiography demonstrated a thrombus attached to the tip of the Port-a-Cath and also the presence of a patent foramen ovale. After an initial period of anticoagulation the defect was closed using a septal occlusion device introduced via a cardiac catheter. The boy's neurological signs completely resolved and he remains free from further thromboembolic episodes. Whilst pulmonary embolism has been described before in relation to a totally implantable venous access device, this is believed to be the first description of a paradoxical embolism in relation to such a device.

5/88. Paradoxical emboli: demonstration using helical computed tomography of the pulmonary artery associated with abdominal computed tomography.

    We report the case of a 60-year-old woman with a recent history of a cerebrovascular accident. Because of clinical suspicion of pulmonary embolism and negative Doppler ultrasound findings of the lower limbs, spiral computed tomography of the pulmonary artery was performed and demonstrated pulmonary emboli. We emphasize the role of computed tomography of the abdomen, performed 3 min after the thoracic acquisition, which showed an unsuspected thrombus within the abdominal aorta and the left renal artery with infarction of the left kidney. Paradoxical embolism was highly suspected on computed tomography data and confirmed by echocardiography which demonstrated a patent foramen ovale.

6/88. Septic paradoxical embolus through a patent foramen ovale after pacemaker implantation.

    A case of a septic paradoxic embolus due to an infected pacemaker lead associated with a patent foramen ovale (PFO) is described. Treatment consisted of immediate intracardiac embolectomy, pericardial patch closure of the PFO, total removal of the infected pacemaker lead and generator, and placement of a new permanent epicardial lead pacemaker system.

7/88. A case of acute pulmonary embolism and acute myocardial infarction with suspected paradoxical embolism after laparoscopic surgery.

    We describe the case of a 59-year-old Japanese man who had an acute pulmonary embolism in addition to acute myocardial infarction after a laparoscopic cholecystectomy. The posterior descending coronary artery was totally occluded. and direct percutaneous transluminal balloon angioplasty was performed. The pulmonary embolism was diagnosed by lung perfusion scanning and was treated with anticoagulant therapy. A patent foramen ovale and right-to-left atrial shunting of blood were detected by contrast transesophageal echocardiography. Paradoxical embolism is a rare complication of pulmonary embolism and may have been responsible for the acute myocardial infarction in our patient.

8/88. pulmonary embolism complicated by patent foramen ovale and paradoxical embolization.

    We present the case of a 74-year-old male with chest pain, dyspnea, and syncope secondary to an acute pulmonary embolism complicated by a patent foramen ovale with straddling thrombus and paradoxical embolization. We review the literature with specific focus on the pathogenesis and acute treatment of this life-threatening occurrence.

9/88. Paradoxical embolism-report of a case involving four organ systems.

    Paradoxical embolism through a patent foramen ovale (PFO) can involve multiple organs simultaneously. The most commonly involved sites are the cerebrum and the extremities. Paradoxical embolism to coronary arteries or upper extremities is relatively uncommon. We report a case of acute pulmonary embolism and paradoxical embolism through a patent foramen ovale involving the left upper extremity, brain, and coronary artery. early diagnosis in the emergency department was made by a trans-esophageal echocardiogram, and the patient was successfully treated with intravenous t-PA and heparin. patients with acute pulmonary embolism or deep venous thrombosis who also develop signs of systemic embolism should be evaluated for a patent foramen ovale.

10/88. Primary right atrial synovial sarcoma manifesting as transient ischemic attacks.

    Primary tumors of the heart are rare and most of them benign. The majority of benign cardiac tumors are myxomas while almost all malignant cardiac tumors are sarcomas. We present a case of primary right atrial synovial sarcoma, a form of sarcoma particularly rare in the heart. The tumor manifested clinically as transient ischemic attacks probably related to a patent foramen ovale allowing paradoxical tumor embolization.
