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.

E-055 Endovascular Therapy for Patients with Acute Large MCA Territory Ischemia: Its Effect on the Risk of Subsequent Development of Deep Venous Thrombosis
ConclusionsIn patients with acute large MCA territory ischemia, endovascular recanalization therapy appeared to decrease the risk of developing subsequent DVT or PE. However, a larger sample size is needed to demonstrate statistical significance. Interestingly, majority of DVT were developed on the side of the extremity contralateral to the affected cerebral hemisphere.DisclosuresZ. Li: None. M. Cox: None.

O-012 Emergent Endovascular Management of Long-segment Carotid Artery Dissections in Acute Ischemic Stroke Intervention with Multiple Tandem Stents
ConclusionTandem stent reconstruction for the treatment of long segment and flow limiting carotid dissections is technically safe and effective with favorable clinical outcomes in acute ischemic stroke intervention, allowing for successful thrombectomy, vessel salvage, restoration of cerebral perfusion, and prevention of recurrent thromboembolic stroke.DisclosuresS.

Timing of deep vein thrombosis formation after aneurysmal subarachnoid hemorrhage.
CONCLUSIONS DVT formation most commonly occurs in the first 2 weeks following aSAH, with detection in this cohort peaking between Days 5 and 9. Chemoprophylaxis is associated with a significantly lower incidence of DVT. PMID: 26162047 [PubMed - as supplied by publisher]

Acute Stroke After Carotid Endarterectomy: Time for a Paradigm Shift? Multicenter Experience With Emergent Carotid Artery Stenting With or Without Intracranial Tandem Occlusion Thrombectomy
CONCLUSION: Emergent endovascular evaluation in the setting of acute post--carotid endarterectomy thrombosis is a safe and timely treatment option, with the benefit of detecting and treating embolic intracranial lesions. Immediate angiography and intervention in this rare surgical complication show promising initial results.

E-006 Familial Incidence of the Congenital Torcular Dural Arteriovenous Shunt
Purpose There are several hereditary disorders that are well known to be associated with arteriovenous malformations (AVMs) involving the central nervous system including Sturge-Weber, Klippel-Trenaunay-Weber, and Parkes-Weber syndromes as well as hereditary haemorrhagic telangiectasia and hereditary neurocutaneous angiomatosis. Furthermore, familial incidence of AVMs in the absence of congenital hereditary disorders also has been reported. Herein, we describe the occurrence of the giant torcular herophili (TH) dural arteriovenous fistula (AVF) in two pediatric cousins treated with endovascular embolization. Case report C...

P-020 Emergent Carotid Artery Stenting with or without Intracranial Tandem Occlusion Lesions Following Carotid Endarterectomy
Conclusion Emergent endovascular evaluation in the setting of acute post CEA thrombosis is a safe and timely treatment option, with the benefit of detecting and treating embolic intracranial lesions. More investigation is necessary to define the role of immediate angiography and intervention in this rare surgical complication.
