Systemic thrombolysis for stroke in pregnancy
Pregnancy is an exclusion criterion for all clinical trials that validate alteplase in acute stroke, so our knowledge about its use in this condition is relative only to case reports and case series. Herein, we report the successful use of intravenous recombinant tissue-type plasminogen activator (rt-PA) in pregnant women with acute stroke. The patient was a 28-year-old who was 16 weeks pregnant. She presented to our hospital 1 hour after a sudden onset of mothor aphasia, hemiparesis, and hypoesthesia on the right side due to incipient ischemia in the left cerebral hemisphere resulting from ipsilateral middle cerebral arte...

Patent foramen ovale and stroke in intermediate-risk pulmonary embolism.
CONCLUSIONS: PFO and related ischemic strokes are frequent in intermediate-risk pulmonary embolism. TEE is much more efficient than TTE for PFO diagnostic. Considering the high risk of intra-cranial bleeding with thrombolysis in PE, which in part may be due to haemorrhagic transformation of sub-clinical strokes, screening PFO with TEE should be considered in intermediate risk PE when a thrombolytic treatment is discussed.

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...

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...

Prevention of recurrent cryptogenic stroke with percutaneous closure of patent foramen ovale; one year follow-up study with magnetic resonance imaging and Holter monitoring.
CONCLUSION: One-year clinical and MRI follow-up study of patients with cerebral ischemic events and percutaneous closure of PFO showed no recurrent event and no significant complication associated with the procedure. In addition, Holter monitorization demonstrated that the procedure did not increase the incidence of arrhythmias compared with pre-procedural monitoring. PMID: 25655849 [PubMed - in process]

A Case-Based Discussion on the Management of Cryptogenic Stroke and Patent Foramen Ovale in the Patient With a Hypercoagulable Disorder
UP TO 40% of all ischemic strokes are considered cryptogenic, implying a stroke without a definitive etiology.1,2 With a dearth of evidence-guided treatment strategies, the literature surrounding cryptogenic stroke is highly variable and not well-standardized. Even though existing guidelines do not specify the exact testing required, the cryptogenic stroke evaluation includes a variety of imaging modalities (eg, echocardiography, angiography, magnetic resonance imaging, carotid ultrasound) and laboratory investigations (eg, genetic testing, hypercoagulable disorder panels, erythrocyte sedimentation rate).

Localization of Infratentorial Lesion could Predict Patent Foramen Ovale as an Etiology in Embolic Stroke of Undetermined Source
CONCLUSIONS: Infratentorial lesions may be independently associated with PFO in patients with ESUS. The presence of infratentorial lesions could predict the presence of PFO in ESUS cases.PMID:33952811 | DOI:10.5551/jat.61200

Cerebral Infarction in a Case of Parry-Romberg Syndrome
Our objective is to report a rare coexistence of Parry-Romberg disease and ischemic stroke. Here, we report the case of a 34-year-old woman with Parry-Romberg syndrome who developed cerebral infarction. This patient developed sudden left-sided weakness and was admitted to our hospital. Magnetic resonance imaging revealed acute cerebral infarction in the posterior limb of the right internal capsule. The patient had been diagnosed with Parry-Romberg syndrome at the age of 12, and she had a history of migraine without aura. Transesophageal echocardiography revealed a patent foramen ovale, but no atrial septal aneurysm or deep...

Simultaneous onset of myocardial infarction and ischemic stroke in a patient with atrial fibrillation: Multiple territory injury revealed on angiography and magnetic resonance
An 84-year-old man with a history of hypertension and paroxysmal atrial fibrillation (AF) who received no anticoagulant drugs experienced acute chest pain and transient loss of consciousness. He was transferred to our emergency room. His initial electrocardiogram showed sinus rhythm with ST-segment elevation in the I, aVL, and V1–V6 leads. His blood pressure was 158/92mmHg and his pulse was regular at 70beats per minute. A chest radiograph showed increased heart size and pulmonary vascular congestion. His troponin T level was elevated (more than 0.1ng/mL). He was diagnosed with ST-elevation myocardial infarction (MI) and...

Ovarian Cancer Presenting as Cryptogenic Stroke from Patent Foramen Ovale.
Abstract A 52-year-old woman experienced severe headache, confusion, nausea, dizziness, and diplopia for three days. Magnetic resonance imaging of the brain showed multiple acute and subacute infarcts suggestive of embolic events. Dermatological examination was notable for splinter hemorrhages and macular patches on the fingernails and feet, respectively. Further diagnostic imaging of the chest and abdomen revealed pulmonary emboli and an ovarian mass with omental deposits and splenic infarcts. Fine needle aspiration cytology and surgery confirmed a diagnosis of high grade serous adenocarcinoma of the ovary with c...

Increased Blood Residence Time as Markers of High-Risk Patent Foramen Ovale
AbstractPrevious investigations have suggested that patients with patent foramen ovale (PFO) often have an atrial dysfunction, like to that observed in patients with atrial fibrillation (AF) which may concur to an increased risk of cryptogenic stroke. The aim of the study is to compare the atrial resident time (Rt) of PFO patients to those with sinus rhythm (SR) and AF using patient-specific 3D computational fluid dynamics (CFD) analysis. Models of left atrium (LA) hemodynamics were obtained from time-resolved CT scans and transthoracic echocardiography (TTE). Enrolled patients were divided into three groups: 30 healthy su...

Survey on APS diagnosis and antithrombotic treatment in patients with ischaemic stroke, other brain ischaemic injury or arterial thromboembolism in other sites: Communication from ISTH SSC Subcommittee on Lupus Anticoagulant/Antiphospholipid Antibodies (LA/aPL)
CONCLUSIONS: Much of the variation in practice reflects the lack of evidence-based recommendations. The survey results should inform the development of a more uniform multidisciplinary consensus approach to diagnosis and antithrombotic treatment.PMID:37391096 | DOI:10.1016/j.jtha.2023.06.020
