Hemodynamic outcomes of stenting for vertebrobasilar insufficiency in patients with a low flow state
CONCLUSIONS: Our series demonstrates angioplasty and stenting significantly improve intracranial flow over long-term. Angioplasty and stenting may improve the natural history of low-flow VB atherosclerotic disease.PMID:37386804 | DOI:10.1177/15910199231185801

Role of artificial intelligence and machine learning in the diagnosis of cerebrovascular disease
ConclusionThe implementation of AI and ML algorithms to supplement clinical practice has conferred a high degree of accuracy, efficiency, and expedited detection in the clinical and radiographic evaluation and management of ischemic and hemorrhagic strokes, AVMs, and aneurysms. Such algorithms have been explored for further purposes of prognostication for these conditions, with promising preliminary results. Further studies should evaluate the longitudinal implementation of such techniques into hospital networks and residency programs to supplement clinical practice, and the extent to which these techniques improve patient...

Pial synangiosis for moyamoya syndrome in children with sickle cell anemia: a comprehensive review of reported cases.
Conclusions Pial synangiosis in patients with SCA, MMS, and brain ischemia appears to be a safe and effective treatment option. Transcranial Doppler and/or MRI screening in asymptomatic patients with SCA is recommended for the diagnosis of MMS. PMID: 24380478 [PubMed - in process]

Thrombectomy with the Penumbra 5 MAX ACE Achieves More Efficient Recanalization (P6.273)
CONCLUSIONS:The 5 MAX ACE yields more efficient revascularization (greater reperfusion achieved in significantly shorter procedural times), with minimal vessel trauma and resultant hemorrhage and greater decline in neurological dysfunction at discharge.Disclosure: Dr. Janjua has nothing to disclose.

Unstable moyamoya disease: clinical features and impact on perioperative ischemic complications.
CONCLUSIONS Unstable moyamoya disease, more prevalent in younger patients and those with underlying disease, is a possible risk factor for perioperative ischemic complications. Recognition of unstable moyamoya disease may contribute to an improved surgical result through focused perioperative management based on appropriate surgical risk stratification.

Identifying the ischaemic penumbra using pH-weighted magnetic resonance imaging
The original concept of the ischaemic penumbra suggested imaging of regional cerebral blood flow and metabolism would be required to identify tissue that may benefit from intervention. Amide proton transfer magnetic resonance imaging, a chemical exchange saturation transfer technique, has been used to derive cerebral intracellular pH in preclinical stroke models and has been proposed as a metabolic marker of ischaemic penumbra. In this proof of principle clinical study, we explored the potential of this pH-weighted magnetic resonance imaging technique at tissue-level. Detailed voxel-wise analysis was performed on data from...

Etiology of Corpus Callosum Lesions with Restricted Diffusion
Conclusions More than half of lesions with diffusion restriction in the corpus callosum are due to a nonvascular cause. Clinical and radiographic characteristics can help distinguish vascular from nonvascular lesions in the corpus callosum. Nonvascular lesions are more likely to be seen in younger patients without vascular risk factors and are more often accompanied by enhancement and edema. Vascular lesions are most commonly due to atypical stroke etiologies, and these patients may require additional diagnostic testing.

Safety and Efficacy of Surgical Resection of Unruptured Low-grade Arteriovenous Malformations From the Modern Decade
CONCLUSION: Surgical resection of low-grade unruptured bAVMs is safe, with a high rate of improvement in functional status and seizure reduction. Although transient postoperative neurological deficit was observed in some patients, permanent treatment-related neurological morbidity was rare.

Natural History and Management of Blunt Traumatic Pseudoaneurysms of the Internal Carotid Artery: The Harborview Algorithm Based Off a 10-Year Experience
Conclusions: Traumatic ICA pseudoaneurysms are safely treated with daily aspirin, embolic monitoring, and radiographic surveillance. Acute stroke or hemorrhage, or delayed radiographic progression, are indications for endovascular or surgical treatment.

A multiparameter model predicting in-hospital mortality in malignant cerebral infarction
Abstract: The early identification of patients with large hemisphere infarctions (LHIs) at risk of fatal brain edema may result in better outcomes. A quantitative model using parameters obtained at admission may be a predictor of in-hospital mortality from LHI. This prospective study enrolled all patients with LHI involving>50% of the middle cerebral artery (MCA) admitted to our neurological intensive care unit within 48 hours of symptom onset. Early clinical and radiographic parameters and the baseline CHADS2 score (congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke [double weight]) w...

Assessment of the interaction of age and sex on 90-day outcome after intracerebral hemorrhage
Conclusion: Unlike in ischemic stroke, there was no evidence that patient sex modified the effect of age on 90-day outcomes after ICH in a large multiracial/ethnic population. Future studies should evaluate biological reasons for these differences between stroke subtypes. Clinicaltrials.gov identifier: NCT01202864.

P-010 Practice variations in addressing acute tandem carotid occlusions in emergent large vessel occlusion strokes
Conclusion For tandem occlusions with cervical ICA involvement, acute stenting with adjunctive angioplasty, is a current prevailing practice for recanalization of the extracranial ICA. There is considerable variability in antiplatelet protocols, with a slight favoring of the administration of loading doses of aspirin and clopidogrel before stent deployment. Variability is also present for anesthesia, with general anesthesia having a significant role. Disclosures S. Coffman: None. S. Trott: None. A. Alhajeri: None. J. Fraser: None.

Vasculitis and neurobrucellosis: Evaluation of nine cases using radiologic findings
ConclusionsWe aimed to present our cases due to the fact that this disease should be kept in mind in the differential diagnosis of patients with stroke and similar neuropsychiatric findings. Vascular syndromes are rarely seen in inflammation in Neurobrucellosis. Neurobrucellosis should be kept in mind in the differential diagnosis of stroke and patients with similar neuropsychiatric findings.
