Patient and aneurysm factors associated with aneurysm recanalization after coiling
Conclusions Several factors are identified by the ARETA study as playing a role in aneurysm recanalization after coiling: current smoking, aneurysm status (ruptured), aneurysm size (≥10 mm), neck size (wide neck), and aneurysm location (middle cerebral artery). This finding has important consequences in clinical practice. Trial registration number URL: http://www.clinicaltrials.gov; Unique Identifier: NCT01942512.

Distribution of symptomatic cerebral vasospasm following subarachnoid hemorrhage assessed using cone-beam CT angiography
Conclusions Our study demonstrated that symptomatic cerebral vasospasm following aSAH did not involve arteries smaller than 900 µm, and frequently predominated in middle or distal segments. These results offer new insights into the potential management options for vasospasm using PBA.

Comparing the efficacy and safety of the Skyflow device with those of the Solitaire FR stent in patients with acute ischemic stroke: a prospective, multicenter, randomized, non-inferiority clinical trial
Conclusion Endovascular thrombectomy with the Skyflow stent retriever was non-inferior to Solitaire FR with regard to successful reperfusion in AIS due to LVO (with a pre-specified non-inferiority margin of 12.5%).

A pressing need and opportunity to standardize care in neurointerventional surgery
Neurointerventional surgery is complex and multifaceted, with much of the scope of practice in both hemorrhagic and ischemic stroke outside the direction offered by randomized clinical trials. The gaps in guidance for clinicians have been filled in many instances by recommendations from expert panels, such as the Society of Neurointerventional Surgery’s Standards and Guidelines committee. The guidelines created by this and other societal committees attempt to summarize the available data within a given topic and provide a corresponding level of evidence to provide clinicians with the most up to date direction for evi...

Predictors of unfavorable outcome in stent-assisted coiling for symptomatic unruptured intracranial spontaneous vertebral artery dissecting aneurysms (uis-VADAs): results from a multicenter study
Conclusions This multicenter study indicated that preprocedural ischemic infarctions, diabetes mellitus, and procedural complications were related to unfavorable clinical outcomes in the reconstructed uis-VADAs.

Predictors of incomplete aneurysm occlusion after treatment with the Pipeline Embolization Device: PREMIER trial 1 year analysis
Conclusions The results of our study are consistent with previous retrospective series and warrant consideration for technique adaptations to achieve higher occlusion rates. Further follow-up is needed to assess progression of aneurysm occlusion and clinical behavior in these cases.

Endovascular treatment of ruptured anterior communicating aneurysms: a 17-year institutional experience with coil embolization
Conclusions Endovascular treatment of ruptured ACoA aneurysms is safe and is associated with low mortality and retreatment rates. Younger patients with favorable functional status and larger aneurysm size are more likely to be retreated. Ruptured aneurysms <4 mm, although prevalent in the study (29%), never required retreatment.

Thrombectomy in special populations: report of the Society of NeuroInterventional Surgery Standards and Guidelines Committee
Background The purpose of this guideline is to summarize the data available for performing mechanical thrombectomy (MT) for emergent large vessel occlusion (ELVO) stroke in special populations not typically included in large randomized controlled clinical trials, including children, the elderly, pregnant women, patients who have recently undergone surgery, and patients with thrombocytopenia, collagen vascular disorders, and endocarditis. Methods We performed a literature review for studies examining the indications, efficacy, and outcomes for patients undergoing MT for ischemic stroke aged <18 years and >80 years, p...

Commentary on 'Systematic CT perfusion acquisition in acute stroke increases vascular occlusion detection and thrombectomy rates
In their JNIS study, Olive-Gadea et al present a retrospective single-center study demonstrating that inclusion of systematic CT perfusion (CTP) in acute stroke imaging protocols improves the detection of intracranial vessel occlusions and helps to identify additional endovascular treatment (EVT) candidates compared with using CT angiography (CTA) alone.1 Their sample group consisted of 338 consecutive patients with suspected acute ischemic stroke who underwent urgent non-contrast CT, CTA, and CTP. One hundred and fifty-seven (46.5%) patients had hypoperfusion with a Tmax >6 s (RAPID software) in an area congruent with ...

The ARTISSE intrasaccular device for intracranial aneurysm treatment: short-term, mid-term and long-term clinical and angiographic results
Conclusion The ARTISSE ISD was successfully deployed in all nine cases. There were, however, several procedure-related complications and results in terms of angiographic aneurysm occlusion were modest.

Bridging thrombolysis in atrial fibrillation stroke is associated with increased hemorrhagic complications without improved outcomes
Conclusion In this large thrombectomy registry, AF patients exposed to IVT before MT had increased hemorrhagic complications without improved functional outcomes, in contrast with non-AF patients. Prospective trials are warranted to assess whether AF patients represent a subgroup of LVO patients who may benefit from a direct to thrombectomy approach at thrombectomy capable centers.

O10 The necessity of monitoring platelet response and adjusting antiplatelet agents for endovascular treatment of unruptured intracranial aneurysms: a single-center, retrospective, cohort study
ConclusionActive monitoring and adjustment antiplatelet agents did not reduce ischemic complications in endovascular treatment; however, tended to reduce the ischemic complication, especially in flow diversion. Low-dose prasugrel may be feasible without increasing hemorrhage in the endovascular treatment of unruptured intracranial aneurysms.ReferencesLi W.

O14 Benefit of thrombectomy in patients with extensive baseline stroke depends on early ischemic lesion water uptake: results from the I-LAST study
DiscussionEarly NWU was an independent predictor of clinical outcome, and might serve as an indicator of futile MT in low ASPECTS patients.
