Pulmonary Arteriovenous Malformations and Risk of Stroke
Pulmonary arteriovenous malformations (PAVMs) are rare, with an estimated incidence of 2 to 3 cases per 100,000, with most PAVMs (50%–80%) occurring in patients with hereditary hemorrhagic telangiectasia. Hypoxemia and orthodeoxia are some of the more common clinical presentations. The estimated risk of stroke secondary to PAVMs is as high as 2.6% to 25.0%. A combination of chest radiograph and contrast echocardiography is a good screening evaluation in patients with suspected PAVMs. Transcatheter therapy is the most suitable therapeutic option in most patients with PAVMs, and a variety of devices can be used to occlude the PAVMs.

Use of Platelet Function Testing Before Pipeline Embolization Device Placement Clinical Sciences
Conclusions—Clopidogrel nonresponders experienced a significantly higher rate of thromboembolic complications when compared with clopidogrel responders. However, this risk seems to be mitigated in nonresponders who were switched to ticagrelor or received a clopidogrel boost within 24 hours pre-procedure.

Endovascular mechanical thrombectomy for cerebral venous sinus thrombosis: a systematic review
Conclusions EMT is an effective salvage therapy for refractory CVST, with a reasonable safety profile. Chemical thrombolysis, in conjunction with EMT, did not appear to result in additional harm or benefit. Further analysis is warranted to determine predictors of success after EMT for CVST.

Letter to the Editor: Pneumocephalus: Is the needle size significant?
Discussion. Pneumocephalus is defined by two mechanisms: a ball-valve and an inverted bottle concept.1 The ball-valve type implies positive pressure events, such as coughing or valsalva maneuvers, that prevent air escape. Tension pneumocephalus is included in this mechanism, causing a parenchymal mass effect. The inverted bottle theory includes a negative intracranial pressure gradient following cerebrospinal fluid drainage, relieved by air influx. A small pneumocephalus is usually sealed by blood clots or granulation, allowing spontaneous reabsorption and resolution.[1] Otherwise, the lateral positioning of a patient duri...

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Antiplatelet treatment compared with anticoagulation treatment for cervical artery dissection (CADISS): a randomised trial
Publication date: Available online 12 February 2015 Source:The Lancet Neurology Background Extracranial carotid and vertebral artery dissection is an important cause of stroke, especially in young people. In some observational studies it has been associated with a high risk of recurrent stroke. Both antiplatelet drugs and anticoagulant drugs are used to reduce risk of stroke but whether one treatment strategy is more effective than the other is unknown. We compared their efficacy in the Cervical Artery Dissection in Stroke Study (CADISS), with the additional aim of establishing the true risk of recurrent stroke. Methods W...

E-019 tcar
ConclusionsOur analysis of a single-center cohort demonstrates that TCAR is a safe and effective treatment for symptomatic carotid stenosis, with a low perioperative stroke risk. The present study’s findings concur with the combined adverse outcome rate of 3.5% reported in the ROADSTER trial.Disclosures A. Bajaj: None. S. Monje: None. C. Ayala: None. J. Poggi: None. E.

E-124 Timing surgery and hemorrhagic complications in endocarditis with concomitant cerebral complications
ConclusionsPatients with radiographic evidence of ischemic stroke from septic emboli can safely undergo valvular surgery for IE without increased risk of symptomatic hemorrhage. We advocate for baseline CTA screening to evaluate for IIA in patients who present with a primary diagnosis of IE and propose a management algorithm.Disclosures B. Lucke-Wold: None.

Is There an Increased Risk of Intracranial Hemorrhage When Treating Patients Who Are Currently on Dual Anti-Platelets with IV tPA? (P01.233)
CONCLUSIONS: In our cohort, there was no additional risk of hemorrhagic complications in patients on dual antiplatelet therapy who received IVtPA, prospective studies are needed to confirm this finding.Disclosure: Dr. Kung has nothing to disclose.

Cn-20 * bevacizumab causing recurrent cerebral infarction in a patient with glioblastoma: a previously undocumented phenomenon
CONCLUSIONS: Here we describe a case of an ischemic stroke with radiographic correlate while on bevacizumab, with clinical improvement arrested by the development of a recurrent stroke when bevacizumab was restarted. Interestingly, the distal arteries within the stroke bed appeared somewhat attentuated, suggestive of radiation vasculopathy. This case, describing a previously undocumented phenomenon, raises the possibility of a synergistic effect of bevacizumab and radiation vasculopathy. It may be that radiation vasculoapthy alone is typically insufficient to cause ischemia, but the addition of bevacizumab may precipitate ...

P-001 Permanent Implantation of the Solitaire Device as a Bailout Technique for Large Vessel Intracranial Occlusions
ConclusionWith the recent over-whelming evidence demonstrating the effectiveness endovascular therapy in acute ischemic stroke, the expansion of stroke therapy requires that a variety of techniques be available to the operators. Permanent implantation of the Solitaire stent achieves adequate distal flow and good clinical outcomes in the setting of AIS. This case series suggests this technique provides a safe alternative for difficult cases refractory to other revascularization techniques.Key Wordsstroke, revascularization, stentDisclosuresJ.

Predictors of Acute Neurological Worsening after Endovascular Thrombectomy
Conclusion: Our single-center retrospective cohort result is limited by small sample size. It showed that high admission BG is an independent predictor of NW after EVT and ultimately leads to poor outcome.Intervent Neurol 2019;8:172 –179

The Routine Follow-up Head CT: Is it Still a Necessary Step in the Thrombolysis Pathway?
ConclusionsThe 24-h head CT scan does not change management for most patients, particularly those with low National Institutes of Health Stroke Scale scores who do not undergo MT. Consideration should be given to removing routine follow-up imaging from postthrombolysis protocols in favor of an examination-based approach.
