Clot Through the Heart: Paradoxical Embolism With Thrombus-in-Transit at Multidetector Computed Tomography

We present the case of a 67-year-old man with concomitant stroke and pulmonary embolism 1 day after radiofrequency catheter ablation for refractory atrial tachycardia. A chest computed tomographic angiogram revealed “thrombus-in-transit” across a patent foramen ovale, confirming the diagnosis of paradoxical embolism. Paradoxical embolism is a rare definitive diagnosis. Our case is a key demonstration of the even rarer instance where such a diagnosis is confirmed at multidetector computed tomography.

We report a case of a 50 ‐year‐old male taxi driver who was diagnosed with a massive saddle pulmonary embolism, leg deep venous thromboembolism, and pending paradoxical embolus through a PFO with systemic embolization. The patient had an inferior vena cava (IVC) filter inserted immediately followed by surgical thromboem bolectomy and closure of PFO. He was discharged home 1 month after surgery. Surgery is the treatment of choice for preventing systemic embolization particularly cryptogenic stroke and its sequelae from pending paradoxical embolus. Preoperative IVC filter is a useful adjunct to prevent ongoing thromb oem...

Conclusion: Frequency of recent ischemic stroke in patients with symptomatic PE was higher in patients with PFO than in those without PFO. This finding supports the hypothesis that paradoxical embolism is an important mechanism of ischemic stroke in patients with PFO. Primary Funding Source: French Ministry of Health.

Conclusion An occult preexisting atrial fibrillation may lead to unnecessary percutaneous foramen ovale closure in a significant proportion of patients. A 6-month loop-recorder monitoring may improve the patient oriented decision-making.

We report the case of a 42-year-old female who was hospitalized for stroke. Detailed investigations revealed the existence of a PFO, pulmonary embolism, and ovarian vein thrombosis extending to inferior vena cava. She had a uterine myoma to be operated on but no other thrombophilic disorders. Anticoagulation therapy with direct oral anticoagulant successfully reduced the thrombus and prevented the recurrence of paradoxical embolism.

A 51-year-old man was diagnosed with eosinophilic granulomatosis with polyangiitis 6 years ago due to asthma, sinusitis, hypereosinophilia, and peripheral neuropathy based on the diagnostic criteria of American College of Rheumatology, and corticosteroid therapy achieved a remission. One year ago, he was hospitalized due to deep venous thrombosis (DVT) and pulmonary embolism, and rivaroxaban was administrated. He was admitted to our hospital for acute onset of diplopia and right hemiparesis. Peripheral blood examinations disclosed leukocytosis with hypereosinophilia.

Abstract Paradoxical embolism should be suspected in front of a clinical phenomenon of thromboembolism associated with an anatomical right-to-left shunt. Others potential cardiac sources of thromboembolism must be ruled out. Strokes constitute the most frequent clinical manifestations of paradoxical embolism. Right-to-left left shunts are in connection with intracardiac defects (atrial septal defect and patent foramen ovale) or pulmonary arteriovenous malformations. The probability that a discovered PFO is stroke-related can be evaluated by a score. Therapeutic approaches for secondary prevention of recurrent stro...

CONCLUSION: This systematic review showed that surgery was associated with a lower overall incidence of post-treatment embolic events and a lower 60-day mortality in patients with trapped thrombus in a PFO. In patients without initial shock or arrest, thrombolysis was related with a higher 60-day mortality compared with surgery. PMID: 28955396 [PubMed]

Cerebral embolism is typically caused by a cardiogenic thrombus. The patent foramen ovale is a well-known cause of paradoxical embolism. However, some idiopathic cases of stroke have been reported. Such strokes are designated as embolic stroke of undetermined sources. Among them, lung lobectomy may be a new embolic risk factor for cerebral embolism. The risk of thrombus formation is high at the pulmonary vein stump after lung lobectomy, especially in the left upper lobe. Interestingly, the risk remains several years after surgery.

We present a case of a 37-year-old male who had deep venous thrombosis with acute massive pulmonary embolism and stroke. Transesophageal echocardiography revealed large straddling thrombus in patent foramen ovale along with branch pulmonary artery embolus. Patent foramen ovale was closed and pulmonary artery embolus was removed surgically. We conclude that surgery is the best mode of management in the presence of patent foramen ovale.
