A comparison of contrast transthoracic echocardiography and contrast transcranial Doppler in cryptogenic stroke patients with patent foramen ovale
ConclusionBoth cTTE and the cTCD can be used for preliminary PFO findings. The semiquantitative shunt grading of cTCD and cTTE can suggest the size of the PFO and the next course of treatment. The cTTE may be more significant to a safe PFO (a PFO does not have right ‐to‐left shunts, RLSs). Combining cTTE and TEE could help diagnose PFO and assess CS risk.

Stroke in sickle cell disease and the promise of recent disease modifying agents
Sickle cell disease (SCD) is an inherited hemoglobinopathy affecting approximately 100,000 individuals in the United States. Cerebrovascular disease is among the most common and debilitating complications of SCA, with 53% experiencing silent cerebral infarct by age 30 and 3.8% experiencing overt stroke by age 40  years. This review highlights the burden of cerebrovascular disease in SCD, including both stroke and silent cerebral infarct (SCI). We then discuss the pathophysiology of stroke and cerebral fat embolism in the absence of a patent foramen ovale.

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...

Prevention of Recurrent Stroke in Patients with Patent Foramen Ovale
Patent foramen ovale (PFO) is common and only rarely related to stroke. The high PFO prevalence in healthy individuals makes for difficult decision making when a PFO is found in the setting of a cryptogenic stroke, because the PFO may be an incidental finding. Recent clinical trials of device-based PFO closure have had negative overall summary results; these trials have been limited by low recurrence rates. The optimal antithrombotic strategy for these patients is also unknown. Recent work has identified a risk score that estimates PFO-attributable fractions based on individual patient characteristics, although whether thi...

Orthodeoxia-platypnea syndrome and stroke: Overlapping pathophysiology
Orthodeoxia-platypnea syndrome (OPS) is a rare cause of dyspnea and hypoxemia induced by upright positioning due to orthostatic conditions [1]. Right-to-left interatrial shunt due to an atrial septal defect or patent foramen ovale (PFO) is the most common cause of this syndrome [2]. Although PFO has been implicated as a potential cause of paradoxical embolism and cerebral embolism in cryptogenic stroke [3], OPS due to PFO has rarely been described presenting as stroke [2,4,5].

Impact of BNP on cryptogenic stroke without potential embolic sources on transesophageal echocardiography
This study sought to analyze the clinical signs of cryptogenic stroke (CS) without such embolic etiologies and to examine the association between CS and brain natriuretic peptide (BNP), which is currently unknown.

Stroke Due to Air Embolism Related to Laser Ablation of Accessory Vein (P4.357)
Conclusions: Air embolism leading to devastating stroke may occur few hours after laser treatment of varicose veins. Chest symptoms associated with the procedure should raise the possibility of air embolism. Immediate therapeutic measures like 100[percnt] oxygen, hyperbaric oxygen chamber and/or hypothermia should be considered to prevent neurologic complications.Disclosure: Dr. Kale has nothing to disclose.

Selective associative phonagnosia after right anterior temporal stroke
We report the case of a 48 year old men who developed a selective impairment in famous voice recognition after ischemic stroke in right subcortical structures (lenticular nucleus and head of the caudate) and right anterior temporal lobe. He underwent fibrinolytic treatment. During the following days he progressively recovered and was discharged without neurological focal sign. Patent foramen ovale was found. When he got back to his house he noticed that he was unable to recognize the voice of his favoured singers and needed to ask who was the singer to his relatives. Neuropsychological examination revealed a selective impa...

Left Upper Lung Lobectomy Is an Embolic Risk Factor for Cerebral Infarction
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.

Patent foramen ovale closure versus medical therapy for cryptogenic stroke: An updated meta-analysis
The efficacy of patent foramen ovale (PFO) closure for secondary stroke prevention in cryptogenic stroke (CS) patients with PFO is uncertain. This meta-analysis aims to assess whether PFO closure is superior to medical therapy.
