Cardioembolic Sources in Patients With Small Single Subcortical Infarcts
Transthoracic echocardiogram (TTE) is widely used as part of the work-up for ischemic stroke. However, the added utility of TTE in the management of small single subcortical infarcts (SSSI) has not been extensively evaluated. Therefore, we aimed to determine the frequency of high-risk and medium-risk cardioembolic sources diagnosed by TTE in SSSI patients, and whether the findings altered clinical management. We performed a retrospective analysis of a prospective cohort of patients with confirmed acute ischemic stroke enrolled in a single-center observational registry between August 2012 and July 2014. We assessed infarct ...

Ischaemic stroke may symptomatically manifest as migraine aura
Publication date: Available online 19 July 2018Source: Journal of Clinical NeuroscienceAuthor(s): Michael J. Waters, Edmund Cheong, Jim Jannes, Timothy KleinigAbstractMigraine aura is a common stroke mimic. We hypothesised that some patients with typical migraine aura symptoms might have embolic stroke detected as the precipitant. We identified fourteen patients who presented with symptoms consistent with a clinical diagnosis of migraine aura, but demonstrated subsequent evidence of acute infarction on magnetic resonance imaging (MRI). In all patients, migraine aura symptoms were not directly attributable to the vascular l...

Role of echocardiography and cardiac biomarkers in prediction of in-hospital mortality and long-term risk of brain infarction in pulmonary embolism patients
ConclusionsHigh blood troponin T, NT-proBNP, RV dilatation/systolic dysfunction and pulmonary hypertension predicted in-hospital mortality. PFO/RLS presence and ST were predictors of clinically apparent/silent brain infarction.

Acute Ischemic Stroke in a Young Woman With No Known Risk Factors.
CONCLUSION: Onset of neurologic symptoms can be immediate or delayed in patients undergoing venous foam sclerotherapy. Early recognition of neurologic deficits resulting from paradoxical gas embolism and its treatment with hyperbaric oxygen can prevent permanent disability. PMID: 29677415 [PubMed - in process]

Patent Foramen Ovale and the Risk of Cerebral Infarcts in Acute Pulmonary Embolism —A Prospective Observational Study
Pulmonary embolism (PE) is associated with a risk of consecutive paradoxical embolism with brain infarction through a patent foramen ovale (PFO). The aims of this study were to assess the rate of new ischemic brain lesions (IBLs) using magnetic resonance imaging (MRI) during a 12-month follow-up period with anticoagulation and to evaluate the potential relationship with the presence of PFO on transesophageal echocardiography (TEE).

Foreign body granuloma as an unexpected long-term finding after percutaneous closure of a patent foramen ovale
A 67-year-old man was referred to our hospital for catheter ablation of atrial fibrillation. Eight years earlier, prior to diagnosis of atrial fibrillation, the patient suffered an ischaemic stroke. A patent foramen ovale (PFO) was diagnosed and the patient underwent percutaneous PFO closure by implantation of a Premere device (20  mm, St. Jude Medical). One month ago, the patient had another middle-cerebral artery infarction, which was considered cardioembolic due to insufficient anticoagulation. However, transthoracic echocardiography (TTE) obtained on current admission demonstrated a suspicious mass in the left atrium...

An Approach to Working Up Cases of Embolic Stroke of Undetermined Source Stroke

Differential Lesion Patterns on T2WI and FLAIR Sequences in Cryptogenic Stroke Patients With Patent Foramen Ovale
Objectives: The purpose of this study was to determine lesion patterns and stroke mechanisms in cryptogenic ischemic stroke patients with patent foramen ovale (PFO) on T2-weighted magnetic resonance imaging and fluid-attenuated inversion recovery sequences combined. Participants and Methods: Twenty-nine patients with cryptogenic ischemic stroke and an isolated PFO (CS-PFO+ group) compared with 51 cryptogenic stroke patients without PFO (CS-PFO− group) were evaluated and the characteristics of their lesion patterns on T2-weighted and fluid-attenuated inversion recovery sequences combined were investigated. We compared the...

Autism in the Son of a Woman with Mitochondrial Myopathy and Dysautonomia: A Case Report
Conclusion Given emerging evidence that mitochondrial dysfunction, particularly in the electron transport chain needed for cellular energy production, is an underlying pathophysiological mechanism for some varieties of ASD, clinicians should have a high index of suspicion for mitochondrial disease, especially when they encounter a patient with unusual neurological or constitutional symptoms. The prevalence of mitochondrial disease in ASD patients may be as high as five percent, which means that it is not the “zebra”[27] diagnosis that it might be in a non-ASD patient, where prevalence is about 0.01 percent.10 Reference...

Impact of transesophageal echocardiography on clinical management of patients over age 50 with cryptogenic stroke and normal transthoracic echocardiogram
CONCLUSIONIn our study population, when performed subsequent to a normal TTE in patients aged >50 years with cryptogenic stroke, TEE demonstrated a high diagnostic value, but had minimal incremental effect on patient management. Journal of Hospital Medicine 2015. © 2015 Society of Hospital Medicine

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...

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

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...
