Cervical carotid occlusion in acute ischemic stroke: Should we give tPA?
CONCLUSION: Emergent revascularization with acute cICA stenting carries advantages, but its safety is precluded by tPA administration. We suggest a trial which randomizes patients with cICA occlusions to receiving either tPA or dual antiplatelet therapy before surgical intervention, aiming to ultimately improved outcomes in these patients.PMID:35509556 | PMC:PMC9063023 | DOI:10.25259/SNI_176_2022

P-012 Thrombectomy aspiration post-market study in acute stroke: the TAPAS study
ConclusionThe Q Aspiration Catheter is a novel technology that showed comparable deliverability and revascularization rates as other commercially available catheters with no safety concerns. More prospective clinical data is needed to fully assess the Q Aspiration Catheter.AbbreviationsAIS (acute ischemic stroke), MT (mechanical thrombectomy), ASPECTs (Alberta Stroke Program Early CT Score), mTICI (modified TICI score), NIHSS (National Institute of Health Stroke Scale), mRS (modified Rankin Scale), ENT (embolization to a new territory), sICH (symptomatic intracranial hemorrhage)Disclosures F.

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.

Endovascular treatment for AIS with underlying ICAD
Conclusions Despite AIS with underlying ICAD requiring a more complex, technically demanding recanalization strategy than traditional thromboembolic AIS, it appears safe, and good outcomes are obtainable.

O-012 Acute clot formation on the surface of flow diverters can be reduced by using phosphoryl-choline surface modification
Conclusion Our preliminary study supported our hypothesis that using phosphoryl-choline surface modified flow diverter can be useful to decrease the occurrence of micro-clot formation, especially post-angioplasty. Importantly, S-PED reduced clot formation at the origin of covered side-branches. References . AJNR 2015;36:98–107. . J. Neurosurg 2016;1–6. Disclosures M. Marosfoi: None. F. Clarencon: None. E.

E-082 Aggressive endovascular management of massive dural venous sinus thrombosis in the setting of acute myelogenous leukemia
Conclusion DVST is an uncommon cause of stroke. The appropriate diagnosis is imperative as the treatment for DVS is vastly different from the treatment of arterial stroke. Patients who suffer from DVST have a good prognosis and often achieve complete recovery. This case demonstrates the utility of more invasive endovascular treatments for extreme cases that fail to improve, or worsen, following a trial of conventional care. When thrombolysis and thrombectomy alone were not successful, stenting of an underlying dural sinus stenosis was ultimately required for successful recanalization. Disclosures: D. Leonard: None. A.

Novel balloon-and-aspiration method for cerebral venous sinus thrombosis: dental-floss technique.
Abstract Cerebral venous sinus thrombosis is sometimes fatal. The standard treatment for sinus thrombosis is anticoagulation, but endovascular intervention must be considered when medical treatment fails. Mechanical thrombectomy is usually required when a large clot burden exits. Unfortunately, in sinus thrombosis attributable to a clot burden larger than that in an intracranial artery, the conventional technique used for intraarterial acute stroke intervention with a stent retriever and/or aspiration is not very effective. The authors describe here their endovascular approach to mechanical thrombectomy for sinus ...

ConclusionsThe techniques and equipment used for acute stroke intervention may be suitable for acute recanalization of peripheral vessels, under the right circumstances. As with many surgical interventions, a multidisciplinary approach may at times yield a novel and effective strategy for a difficult clinical problem.DisclosuresJ. Dalfino: None. A. Paul: None. J.

Reappraisal of primary balloon angioplasty without stenting for patients with symptomatic middle cerebral artery stenosis.
We describe our experience with primary balloon angioplasty without stenting for symptomatic middle cerebral artery (MCA) stenosis. All patients who underwent balloon angioplasty without stenting for MCA stenosis between 1996 and 2010 were retrospectively reviewed. We evaluated technical success rates, degrees of stenosis, and stroke or death within 30 days. Among patients who were followed-up for > 1 year we evaluated latest functional outcomes, stroke recurrence at 1 year, and restenosis. In total 45/47 patients (95.7%) were successfully treated. Average pre- and postprocedure stenosis rates were 79.9% and 39.5%, resp...

E-031 Treatment of Acute Ischemic Stroke Due to Thrombosis of Stenotic Atherosclerotic Lesions of the Posterior Circulation
Conclusion Endovascular treatment can be performed with high rates of technical success for AIS due to thrombosis at chronic atherosclerotic lesions. In spite of potential for poor outcomes, significant recovery of function is possible following treatment. Further evaluation is warranted to identify those patients most likely to respond to such intervention. Disclosures M. Alexander: None. J. Rebhun: None. S.
