P009/86 Infected giant pseudoaneurysm of extracranial internal carotid artery with extreme vascular tortuosity: Difficulty in accessing the devices in endovascular treatment
ConclusionWhen we deciding treatment strategy, surgery could not be considered due to uncontrolled infection and suggesting inflammatory/erosive changes. Because of no collateral flow, carotid sacrifice could not be considered. Endovascular treatment is preferred option, but treatment strategy should be personalized.Disclosure of InterestNothing to disclose

E-129 Trends in demographic and geographic disparities of stroke-related mortality in older adults in the United States from 1999 to 2020
Stroke is a leading cause of mortality and morbidity in the United States. Many risk factors are controversial, and their relative importance is not fully understood. Elucidating the association between demographic and geographic disparities and stroke-related mortality in older adults will guide policy to alleviate stroke burden. This retrospective cohort study characterizes stroke-related mortality among individuals aged 55 and older in the United States from January 1999 to December 2020 using the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database. Segmented regressio...

E-145 Mortality following mechanical thrombectomy for ischemic stroke in patients with COVID-19
ConclusionOverall, this study indicates that COVID-19 is a predictor of mortality among mechanical thrombectomy. This finding is likely multifactorial but may be related to multisystem inflammation, hypercoagulability, and re-occlusion seen in COVID-19 patients. Treatment-related factors, such as delays in care, may also play a role. Additional research would be needed to further delineate these findings.Disclosures J. Dallas: None. T. Wenger: None. K.

E-164 Symptomatic developmental venous anomaly thrombosis associated with covid-19 infection
We describe a milder case of DVA thrombosis in the setting of COVID-19 infection presenting with unilateral hemiparesis requiring medical management alone. A 41-year-old female with hypertension who presented with left hemiparesis. Non-contrast computed tomography (CT) of head revealed linear calcifications in the right centrum semiovale consistent with DVA. Magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the right corona radiata adjacent to the vascular abnormality. Extensive workup for other causes of ischemic stroke was unrevealing. Cerebral angiography ruled out arteriovenous shunting and did not ...

E-166 The effect of covid-19 on treatment and outcomes following ischemic stroke: a national assessment
ConclusionThis study identified a relationship between COVID-19 diagnosis and worse outcomes for each metric assessed. Most notably, even when controlling for disease-related factors, patients with COVID-19 were significantly less likely to undergo mechanical thrombectomy. Further, COVID-19 was associated with increased in-hospital mortality and worsened discharge disposition, although the exact causal relationship of this is unclear. Several factors might underly this, ranging from systemic/multisystem inflammation and worsened disease severity to logistical barriers to treatment caused by COVID-19. Further research is ne...

E-177 Treatment of ischemic stroke in patients diagnosed with covid-19: a matched analysis of the national inpatient sample
ConclusionsIn this matched NIS analysis of patients treated for ischemic stroke with a concomitant COVID diagnosis, we demonstrate that EVT trends towards, although nonsignificant, higher rates of favorable functional outcomes when compared to medically managed patients.Abstract E-177 Table 1Patients with COVID and Acute Ischemic Stroke Comparing medical management vs EVT 1:1 Nearest Neighbor Matching for EVT based on Age, NIHSS, Gender, and Comorbidities Medically Managed N = 495 1 Endovascular ThrombectomyN = 495 1 p-value 2 Age in years at admission 66.82 ± 16.98 (19.00-90.00), (1.77) 65.67 ± 14.81 (28...

E-223 Improved time to diagnosis with portable MR imaging
ConclusionPortable MRI is a promising innovation with the aim to expand patient access and improve diagnostic times so that critical and potential lifesaving imaging diagnoses can be promptly treated with the urgency that is required. While initial analysis provides evidence that portable MRI has advantages over conventional MRI systems including workflow efficiency and improved patient imaging times, this will need to be compared to the unfortunate negative drawbacks of lessened image resolution and limited imaging sequences that come with the convenience of portable MRI systems. If the hypothesis is further corroborated,...

E-241 Clinicopathologic analysis of COVID-19 associated thrombi in the setting of large vessel occlusion: a prospective case control study
ConclusionThrombi retrieved from COVID-19 positive stroke patients demonstrated RBC predominance.

P-028 Impact of the covid-19 pandemic on the intracranial aneurysm treatment and associated outcomes: a propensity score matching study
Conclusions and RelevanceThe COVID-19 pandemic has significantly impacted the healthcare system and has led to changes in the treatment of various neurological conditions, including ICAs. The pandemic resulted in a shift in the treatment of SAH and an increase in endovascular procedures over open surgical clipping. COVID-19 infection has been associated with an increased risk of ischemic stroke and worsened outcomes for stroke patients. Further research is necessary to understand the long-term effects of the pandemic on the healthcare system and patient outcomes.Disclosures A. Ghaith: None. M. Ghanem: None. E. Greco: None....

E-069 Covid-19 and mechanical thrombectomy: confounder or contributor
ConclusionLate in the pandemic, mortality rates remain very high for patients with COVID-19 undergoing mechanical thrombectomy. This is significant in that later circulating variants appear to cause less severe disease.Disclosures C. Houk: None. N. Ellens: None. G. Kohli: None. D. Schartz: None. D. Proper: None. T.

Surgical management of post-COVID invasive rhino-orbito-cerebral mucormycosis and its outcomes: Role of neurosurgeons in a tertiary care center
CONCLUSION: In high-risk patients, a high level of clinical suspicion combined with appropriate investigations should be performed as soon as possible. Symptoms and early warning signs should not be overlooked, as treatment delays can be fatal. A minimally invasive surgical approach is possible in view of decreasing the morbidity of large craniotomy.PMID:36128146 | PMC:PMC9479606 | DOI:10.25259/SNI_374_2022
