Stroke in Young Military Men With Heterozygous for MTHFR Gene Mutation or Factor V Leiden Gene Mutation Associated With Patent Foramen Ovale: Report of Two Cases and Therapeutic Strategy
We report two cases of Brazilian patients (a 22-year-old male and a 48-year-old male) with ischemic stroke, whose arterial vascular study and echocardiographic investigation did not reveal any steno-occlusive arterial disease or typical cardioembolic finding, such as atrial fibrillation or myocardial dysfunction. A transcranial Doppler ultrasound and a transesophageal echocardiogram showed a patent foramen ovale (PFO), and the laboratory screening for coagulation abnormalities showed heterozygosity for MTHFR C677T and A1298C in one of the patients and heterozygosity for factor V Leiden gene mutations in the other patient. ...

Bubble Test and Carotid Ultrasound to Guide Indication of Transesophageal Echocardiography in Young Patients With Stroke
ConclusionsBubble test and carotid ultrasound could be used for the individual decision for/against TEE in patients with cryptogenic stroke ≤60 years. If they are unremarkable, TEE can be omitted with high safety regarding secondary prevention. If bubble test is positive and/or carotid ultrasound shows atherosclerosis, TEE should be carried out if PFO or aortic atheroma are potentially relevant for further patient management.

Amusia: Unique Presentation of Stroke (P6.261)
CONCLUSIONS:Even though music and speech are similar in principle and execution they are functions of different hemispheres of the brain. Unlike aphasia, anatomical localization of amusia has not been established but it is known that right non dominant hemisphere is concerned with musical ability. Impairment of musical ability in the presence of intact speech can be the only presenting finding in stroke. Their identification is the key to early and appropriate treatment.Study Supported by:NoneDisclosure: Dr. Ramchandani has nothing to disclose. Dr. Alsmaan has nothing to disclose.

Pearls & Oy-sters: Cerebral venous air embolism after central catheter removal: Too much air can kill
A 95-year-old woman with a history of hypertension presented from a long-term care facility for altered mental status in the context of dehydration and hypoglycemia. Multiple attempts to obtain a peripheral IV failed, and a triple lumen catheter was placed into the right internal jugular vein using the Seldinger technique under ultrasound guidance. No complications followed the procedure. The patient was then rehydrated and given multiple ampules of D50, leading to prompt resolution of the hypoglycemia and improvement in her mental status. After resolution of symptoms, the central line was removed, with the head of the bed...

Carotid Artery Free-Floating Thrombus Caused by Paradoxical Embolization From Greater Saphenous Vein Ascending Thrombophlebitis
We report a case of a young woman without cardiovascular risk factors who was admitted to our emergency department with listlessness and altered mental status. The clinical examination revealed right lower limb swelling. Magnetic resonance imaging and contrast-enhanced computed tomographic scans revealed a free floating thrombus of the left internal carotid artery (ICA) with a large bilateral frontal ischemic lesion. The diagnosis of a medium-sized PFO with moderate right-to-left contrast shunting was made after transesophageal echocardiography. No other cardiac sources for embolization were detected, while an ascending th...

Is there a correlation between embolic strokes of undetermined source (ESUS) and patent foramen ovale (PFO)? - A contrasted Transcranial Doppler Ultrasound (cTCD) study. (P6.287)
Conclusions:Massive shunt (the so-called "curtain pattern") during Valsalva maneuver at cTCD was predictive of ESUS in patients with stroke and PFO. The presence of RLS at rest was not statiscally relevant, probably because of the small sample size.Disclosure: Dr. Scavasine has nothing to disclose. Dr. Chamma has nothing to disclose.

Detection of Right‐to‐Left Cardiac Shunt in the Absence of Transcranial Acoustic Bone
CONCLUSIONSWhen transcranial acoustic bone windows are missing, Doppler ultrasound of the cervical submandibular ICA and VAs are valid screening methods to detect RLS due to a PFO.

Transcranial Doppler ultrasound: Clinical applications from neurological to cardiological setting
J Clin Ultrasound. 2022 Oct;50(8):1212-1223. doi: 10.1002/jcu.23344.ABSTRACTTranscranial Doppler (TCD) ultrasonography is a rapid, noninvasive, real-time, and low-cost imaging technique. It is performed with a low-frequency (2 MHz) probe in order to evaluate the cerebral blood flow (CBF) and its pathological alterations, through specific acoustic windows. In the recent years, TCD use has been expanded across many clinical settings. Actually, the most widespread indication for TCD exam is represented by the diagnosis of paradoxical embolism, due to patent foramen ovale, in young patients with cryptogenic stroke. In addition...

Use of Transcranial Doppler (TCD) Ultrasound in the Neurocritical Care Unit
Transcranial Doppler (TCD) is a portable device that uses a handheld 2-MHz transducer. It is most commonly used in subarachnoid hemorrhage where cerebral blood flow velocities in major intracranial blood vessels are measured to detect vasospasm in the first 2 to 3 weeks. TCD is used to detect vasospasm in traumatic brain injury and post-tumor resection, measurement of cerebral autoregulation and cerebrovascular reactivity, diagnosis of acute arterial occlusions in stroke, screening for patent foramen ovale and monitoring of emboli. It can be used to detect abnormally high intracranial pressure and for confirmation of total...
