E-135 Dejerine-roussy syndrome in the setting of right sigmoid sinus thrombosis: a unique case report
DiscussionThis case illustrates the important clinical aspects and physical findings needed to diagnose DRS. The presence of focal allodynia and hyperalgesia with recent cerebrovascular incidents provides significant evidence for DRS. The purpose of this case is to provide awareness and to increase clinical suspicion of DRS during examination, especially in the setting of cerebral venous sinus occlusion as infarction alone may not present as atypical allodynia.Disclosures S.

Thromboembolic infarction caused by an unknown patent foramen ovale 30  years after VA shunt insertion: a case report and review of the literature
ConclusionsThromboembolic events due to a PFO are rare but possible life-threatening complication after VA shunt insertion. Therefore, preoperative cardiac diagnostic might be clinically relevant prior to a VA shunt implantation to avoid such complications.

Management of patent foramen ovale in patients with cryptogenic stroke: Is device closure superior to medical treatment? A brief review.
Conclusion: In cryptogenic stroke patients <60 years with large PFOs, PFO closure seems to be safe and more effective compared to medical treatment alone. For all other patients group, for example, patients >60 years further trials are needed to clarify the role of PFO closure. PMID: 30105130 [PubMed]

Artery of percheron occlusion: a rare cause of coma
Conclusions AOP occlusion is a rare cause of coma and should be suspected in patients who present with acute loss of consciousness, once other common aetiologies are excluded. This case raises pertinent questions regarding the indications and benefits of thrombolysis and/or clot retrieval in such patients.

Advanced imaging in acute ischemic stroke.
Abstract The evaluation and management of acute ischemic stroke has primarily relied on the use of conventional CT and MRI techniques as well as lumen imaging sequences such as CT angiography (CTA) and MR angiography (MRA). Several newer or less-established imaging modalities, including vessel wall MRI, transcranial Doppler ultrasonography, and 4D CTA and MRA, are being developed to complement conventional CT and MRI techniques. Vessel wall MRI provides high-resolution analysis of both extracranial and intracranial vasculature to help identify previously occult lesions or characteristics of lesions that may porten...

Cryptogenic postpartum stroke
Publication date: Available online 18 May 2016 Source:Neurologia i Neurochirurgia Polska Author(s): Dániel Bereczki, Norbert Szegedi, Zoltán Szakács, István Gubucz, Zsolt May An estimated 25–40% of ischemic strokes are classified as cryptogenic, which means the cause of the cerebral infarction remains unidentified. One of the potential pathomechanisms – especially among young patients with no cardiovascular risk factors – is paradoxical embolism through a patent foramen ovale. Pregnancy, cesarean delivery and the postpartum period are associated with an increased risk of cerebrovascular events. Factors tha...

Sensitivity of transcranial doppler and transoesophageal echocardiography for the detection of patent foramen ovale in cryptogenic stroke
Conclusions TCD with bubble test is sensitive and specific for the detection of right–to–left shunts due to PFO confirmed at right heart catheterisation. In this population, TOE had low sensitivity for RLS. There was no difference in physical PFO size between TOE positive and negative patients.

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...
