P005/44 Using the pEGASUS-stent with antithrombogenic properties and single antiplatelet therapy in a case of thrombectomy
IntroductionRescue stenting is used more and more in stroke cases with large-vessel-occlusion or medium-vessel-occlusion refractory to mechanical thrombectomy. The pEGASUS-stent(Phenox) represents a device which is equipped with a hydrophilic polymer coating(HPC) with antithrombogenic properties. The coating allows for implantation under single antiplatelet therapy, thus possibly reducing the risk of bleeding in acute stroke cases.Case HistoryA 79-year-old woman was rushed to emergency room due to left-sided hemiparesis and National-Institutes-of-Health-Stroke-Scale(NIHSS) of 14. Computed-tomography-image showed an occlusi...

Novel technique of stent placement via gateway balloon in intracranial atherosclerosis-associated large vessel occlusion
CONCLUSION: Our preliminary experience suggests possible safety and feasibility of deploying Neuroform Atlas stent through a compatible Gateway balloon microcatheter without the need for ICH-associated microcatheter exchange. Further studies with long-term clinical and angiographic follow-up are warranted to corroborate our initial findings.PMID:37391866 | DOI:10.1111/jon.13139

P90 Intracranial balloon-expandable stents as rescue treatment in acute stroke secondary to atherosclerotic stenotic vessel disease: 10-year single center experience
ConclusionsEmergency application of dual antiplatelet agents and balloon-expandable stents for treatment of acute stroke secondary to intracranial atherosclerotic stenotic disease exhibits a comparably high rate of early reocclusion and low rate of good clinical outcome.ReferencesStracke CP, Fiehler J, Meyer L, et al.

Isolated hand weakness due to brain lesion
Hand Surg Rehabil. 2022 Aug 12:S2468-1229(22)00172-4. doi: 10.1016/j.hansur.2022.08.003. Online ahead of print.ABSTRACTWhen hand weakness is linked to a brain lesion, there is risk of misdiagnosis. A case of hand weakness related to stroke is presented. The electromyography report indicated a segmental lesion of the median nerve at the wrist. Thus, the patient was initially diagnosed with carpal tunnel syndrome, and was referred to the orthopedic department for release surgery. Because the symptom was immediate and did not include hand numbness, the orthopedic surgeon ruled out the previous diagnosis and ordered a head CT ...

E-055 Internal carotid artery reconstruction with flow diverting stents in the treatment of acute ischemic stroke: technical considerations and medical management
ConclusionsFDS appear to be a safe and effective tool for reconstruction of a symptomatic dissection in tortuous cervical ICAs. Their flexibility allows conformation to complex anatomies and they can be traversed multiple times by aspiration catheters/stentrievers. We found excellent patency at follow up. The unique challenges posed by utilization of high-profile stents in acute stroke require appropriate technical execution and medical management.Disclosures E. Orru: None. F. Bounni: None. M.

E-101 Rescue stenting for intracranial stenosis in emergent large vessel occlusion patients using the neuroform atlas stent through the gateway balloon: preliminary report
ConclusionOur preliminary experience showed the diminished risk of guidewire perforation as well as potentially decreased operative time and early reperfusion by deploying the Neuroform stent through a compatible gateway balloon microcatheter. This should be investigated further in large multicenter studiesDisclosures M. Memon: None. T. Nisar: None. J. Lee: None. A. Biswas: None. A. Singla: None. P. Khandelwal: None.

E-187 Pipeline embolization stent for treatment of giant supraclinoid aneurysms: a case series
ConclusionThe Pipeline embolization device is a novel technique that can be utilized for treatment of giant cerebrovascular aneurysms with emerging evidence of immediate and long-term success. Further patient enrollment and clinical trials will be required to assess its efficacy in comparison to other endovascular and surgical approaches for the treatment of giant aneurysms.Disclosures M.

Intracranial atherosclerotic stenosis: risk factors, diagnosis, and treatment
Lancet Neurol. 2022 Feb 7:S1474-4422(21)00376-8. doi: 10.1016/S1474-4422(21)00376-8. Online ahead of print.ABSTRACTIntracranial atherosclerotic stenosis (ICAS) is one of the most frequent causes of stroke worldwide and confers one of the greatest risks of recurrent stroke compared with other causes of stroke. Asymptomatic ICAS is increasingly recognised as a risk factor for silent brain infarctions and dementia, magnifying the global burden of ICAS. Although ICAS is a lumen-based diagnosis, newer diagnostic imaging techniques, such as high-resolution MRI, might help to identify high-risk population subgroups to test interv...

E-004 Focal intracranial vasculopathy as a manifestation of COVID-19-associated acute ischemic stroke
ConclusionTo our knowledge, our case is the first to illustrate the potential for COVID-19 infection to present as a focal intracranial vasculopathy in an otherwise healthy young-patient, resulting in acute ischemic stroke without an underlying hypercoagulable state. Rescue intracranial stenting was necessary to maintain vessel patency and restore intracranial flow.Disclosures A. Mahapatra: None. A. Witek: None. G. Toth: None.

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...
