Applying neurointerventional expertise to save vision from eye strokes
Recent years have seen a dramatic change in the landscape of neurointerventional surgery, in large part due to the significant progress in the treatment of acute ischemic stroke (AIS). This progress has resulted in many thousands of lives saved and the prevention of life-changing morbidity and dependence in many more patients. Although the development of novel endovascular devices and procedural techniques was critical and arguably the ignition for these advances, as we move forward it is the integration of our systems of care and further collaboration with all stakeholders both within and away from the coal face clinical ...

E-110 Bilateral hypoplasia of the internal carotid artery (ICA) and intracranial vasculopathy with 'moyamoya phenomenon in association with alagille syndrome
ConclusionThe educational value of our case lies not only in the rarity of the condition but also in the uniqueness of patient presentation. It would be a helpful addition to the existing literature on rare genetic syndromes with cerebral vasculature involvement.Abstract E-110 Figure 1Disclosures H. Shakeel: None. J. Gandhi: None. R.

Cerebral angiographic features of central retinal artery occlusion patients treated with intra-arterial thrombolysis
Conclusions There was a significant correlation in the severity of steno-occlusive lesions between the OphA and the ipsilateral CA in patients with CRAO. The patients with less severe angiographic features in the CA showed a more improved retinal reperfusion after IAT. The angiographic findings in the CA may serve as a predictive marker for the vessel integrity of the OphA and recanalization outcome after IAT.

267 When investigating stroke is a waste of time
Young stroke should alert clinicians to investigate for unusual causes. A previously well 43-year-old Caucasian female presented with 2 days of punctuated left sided weakness and sensory inattention. MRI demonstrated multiple territory infarcts, predominantly on the right side. With no vascular risk factors, high dose steroids were commenced assuming primary angiitis of the CNS (PACNS). Blood tests including ESR, HIV, an autoimmune and thrombotic screen and blood cultures were negative. A 24-hour ECG and TOE failed to identify an embolic source, though interval MRIs plus CT angi- ography revealed evolving cerebral and sple...

Endovascular treatment of anterior cranial base dural arteriovenous fistulas as a first-line approach: a multicenter study
CONCLUSIONS: Most anterior cranial base DAVFs can be successfully treated via an endovascular approach. Neurological and visual complications are rare, even if the ophthalmic artery is used as the primary access route. Efforts should be focused on prospectively comparing the results of EVT and surgical management.PMID:35395632 | DOI:10.3171/2022.2.JNS212588

EP61 Direct carotid puncture for mechanical thrombectomy in acute ischaemic stroke: a single centre experience and review of the literature
ConclusionDirect carotid puncture is an effective and generally safe approach for EVT, with major access-site related complications seen in <5% of the cases. It should be considered as a bailout technique or primary access approach in selected cases.ReferencesAkpinar CK, et al. Direct common carotid artery puncture: rescue mechanical thrombectomy strategy in acute ischemic stroke. Neurointervention 2020;15(2):60–66.Cord BJ, et al.

E-049 Normalized intraplaque hemorrhage signal on MP-RAGE as a marker for acute ischemic neurological events
ConclusionsThere was no association between the SIR of IPH and acute ischemia on either MP-RAGE or T1-CUBE sequences. Further investigation is required prior to widespread acceptance of SIR as a predictive imaging marker of symptomatic carotid plaque.Disclosures A. Larson: None. W. Brinjikji: None. N. Kroll: None.

Attacked and Shaken by a Dog: A Cause of Traumatic Brain and Carotid Injury in an Infant
Conclusion: Large animal attacks are a rare cause of PTCAD but may be due to the mechanism of shaking during the attack. We propose either CTA or MRA be considered as part of the initial workup in cases where an infant is attacked by a dog or other large animals, preventing delay of treatment.Pediatr Neurosurg

E-088 Investigation of safety termination of antiplatelet therapy after lvis stent-assisted cerebral aneurysm coiling
Conclusion Termination of AT at 3 months postoperatively did not result in ischemic events among patients who underwent LSAC. Neointimal formation of Lvis stent may be a criterion for termination of AT without increasing the risk of ischemic event. Disclosures: K. Takayama: None. K. Myouchin: None. T. Wada: None. S.
