Neuroimaging Findings in Cryptogenic Stroke Patients With and Without Patent Foramen Ovale Clinical Sciences
Conclusions— This is the largest study to report the radiological characteristics of patients with cryptogenic stroke and known PFO status. Strokes that were large, radiologically apparent, superficially located, or unassociated with prior radiological infarcts were more likely to be PFO-associated than were unapparent, smaller, or deep strokes, and those accompanied by chronic infarcts. There was no association between PFO and multiple acute strokes nor between specific echocardiographic PFO features with neuroimaging findings.

Patent Foramen Ovale and Cryptogenic Stroke: The Hole Story Emerging Therapy Critiques
Despite 3 recent randomized clinical trials, the management of patients with cryptogenic stroke and patent foramen ovale remains unsettled. The primary results of Evaluation of the STARFlex Septal Closure System in Patients with a Stroke and/or Transient Ischemic Attack due to Presumed Paradoxical Embolism Through a Patent Foramen Ovale (CLOSURE), Percutaneous Closure of Patent Foramen Ovale in Cryptogenic Stroke (PC), and Randomized Evaluation of Recurrent Stroke Comparing PFO Closure to Established Current Standard of Care Treatment (RESPECT) were the same; the intent to treat analysis for the primary end point in all 3 ...

Differential Lesion Patterns on T2-weighted Magnetic Resonance Imaging and Fluid-attenuated Inversion Recovery Sequences in Cryptogenic Stroke Patients with Patent Foramen Ovale
Background: The present study aimed to determine lesion patterns and the stroke mechanisms in cryptogenic ischemic stroke patients with patent foramen ovale (PFO) on T2-weighted magnetic resonance imaging (T2WI) and fluid-attenuated inversion recovery (FLAIR) sequences combined.Methods: In this retrospective study, 38 patients with cryptogenic stroke and an isolated PFO compared with 51 cryptogenic stroke patients without PFO were evaluated and their characteristics of lesion patterns on T2WI and FLAIR sequences combined were investigated. The number, distribution of small ischemic lesions, and the frequency of multiple sm...

Propensity Score-Matched Analysis of Lesion Patterns in Stroke Patients With Patent Foramen Ovale and Patients With Spontaneous Intracranial Artery Dissection
Conclusion: The present study suggests that lesion patterns observed from DWI of patients with PFO and SIAD might provide clues to the etiology of infarcts. Single lesions (cortical or subcortical) might be a typical feature of PFO associated strokes, while multiple lesions in one vascular territory might be a specific feature of SIAD associated strokes. Introduction Both patent foramen ovale (PFO) and spontaneous intracranial artery dissection (SIAD) are important stroke risk factors, especially in young and middle-aged adults (1–3). About 25% of patients with ischemic stroke are cryptogenic (4), and PFO is ...

Imaging Characteristics of Ischemic Strokes Related to Patent Foramen Ovale Clinical Sciences
Conclusions— A PFO-stroke usually appears as a single cortical or multiple small ischemic lesions in the vertebrobasilar circulation without any visible vessel occlusion on angiography. The recanalization rate is significantly lower than in AF-stroke. These imaging characteristics of PFO-stroke may help to diagnose the mechanism and determine the treatment strategy.

Prevalence of Patent Foramen Ovale in Ischaemic Stroke in Italy: Results of SISIFO Study
Conclusion: If any relationship exists between stroke and PFO, this is more likely in PACI and POCI at a younger age. Our results are consistent with recent findings that underline PFO alone must not be considered a significant independent predictor for stroke; so the presence of PFO alone doesn't permit rushed causal correlations or ‘therapeutic aggressiveness'.Cerebrovasc Dis 2015;39:162-169

Patent Foramen Ovale and Ischemic Stroke in Patients With Pulmonary Embolism: A Prospective Cohort Study.
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.

Cryptogenic stroke
In about a quarter of ischaemic strokes the cause is undetermined, because the investigation is incomplete or delayed, because there are multiple causes or because the stroke is truly cryptogenic. Cryptogenic stroke can be further classified as non‐embolic or embolic. Embolic stroke of undetermined source can be due to paroxysmal atrial fibrillation, minor emboligenic cardiac conditions, atheroembolism, cancer associated and paradoxical embolism through a patent foramen ovale (PFO) or less often a pulmonary fistula. Currently, risk factor control, statins and antiplatelets are the main therapeutic measures to prevent rec...

Value of Eye Movement Exam in Aiding Precise Localization in Stroke (P1.016)
We present an unusual presentation of midbrain stroke presenting with bilateral ptosis in an African American male with vascular risk factors and concurrent use of bevacizumab. This case illustrates how detailed knowledge of anatomy and detailed neurologic exam remain valuable tools for localizing and diagnosing subtle presentations of common neurologic disease. Case description: A 69 year-old African American man with vascular risk factors including hypertension, hyperlipidemia and poorly controlled diabetes experienced sudden onset horizontal diplopia associated with fatigue. The patient presented to the Emergency Depart...

Impact of transesophageal echocardiography on clinical management of patients over age 50 with cryptogenic stroke and normal transthoracic echocardiogram

A Review of the Role of Transthoracic and Transesophageal Echocardiography, Computed Tomography, and Magnetic Resonance Imaging in Cardioembolic Stroke
Med Sci Monit. 2022 Jun 22;28:e936365. doi: 10.12659/MSM.936365.ABSTRACTStroke is a major source of morbidity and mortality worldwide, accounting for the second largest cause of mortality and the third greatest cause of disability. Stroke is frequently preceded by a transient ischemic attack (TIA). The etiologies of 20-30% of ischemic strokes are unknown, and thus are termed "cryptogenic strokes". About 25% of ischemic strokes are cardioembolic. Strokes occur at a rate of around 2% per year in individuals with heart failure with reduced ejection fraction (HFrEF), with a strong correlation between stroke risk and the degree...
