Intraarterial urokinase for thrombus migration after mechanical thrombectomy for large vessel ischemic stroke
CONCLUSION: The results of this study suggest that intraarterial urokinase for MeVO with thrombus migration after MT may safely improve angiographic reperfusion.PMID:34939475 | DOI:10.1177/15910199211069464

Risks of Undersizing Stent Retriever Length Relative to Thrombus Length in Patients with Acute Ischemic Stroke INTERVENTIONAL
CONCLUSIONS: Information about thrombus and stent length is more valuable when combined. High thrombus length/stent retriever length ratios, which may raise the risk of unsuccessful recanalization and embolization in new territories, should be avoided by adapting stent retriever selection to thrombus length whenever possible.

Perceived Limits of Endovascular Treatment for Secondary Medium-Vessel-Occlusion Stroke INTERVENTIONAL
CONCLUSIONS: Physicians’ willingness to treat secondary medium vessel occlusions endovascularly is limited and varies per occlusion location and change in neurologic status. More evidence on the safety and efficacy of endovascular treatment for secondary medium vessel occlusion stroke is needed.

Correlation of Neutrophil to Lymphocyte Ratio with Expression of Neutrophil Extracellular Traps Within Stroke Emboli
CONCLUSIONS: NLR is correlated with the amounts of WBCs, fibrin, NETs and vWF within the thrombi retrieved from AIS patients due to LVO.PMID:34878323 | DOI:10.1177/15910199211065530

Influence of recent direct-to-EVT trials on practical decision-making for the treatment of acute ischemic stroke patients
CONCLUSION: In light of the recent direct-to-EVT trials, a sizeable proportion of stroke physicians appears to be rethinking IVT treatment strategies of EVT-eligible mothership patients with AIS due to LVO in specific situations.PMID:34787489 | DOI:10.1177/15910199211057984

Local Intra-arterial Thrombolysis during Mechanical Thrombectomy for Refractory Large-Vessel Occlusion: Adjunctive Chemical Enhancer of Thrombectomy INTERVENTIONAL
CONCLUSIONS: The use of local intra-arterial urokinase as an adjunct to mechanical thrombectomy may be an effective and safe method that provides better recanalization than the conventional mechanical thrombectomy for refractory thrombus in patients with embolic large-vessel occlusion.

A Uniform Description of Perioperative Brain MRI Findings in Infants with Severe Congenital Heart Disease: Results of a European Collaboration PEDIATRICS
CONCLUSIONS: A broad spectrum of perioperative brain MR imaging findings was found in infants with severe congenital heart disease. We propose an MR imaging protocol including T1-, T2-, diffusion-, and susceptibility-weighted imaging, and MRV to identify ischemic, hemorrhagic, and thrombotic lesions observed in this patient group.

Preprocedural Imaging
AbstractBackgroundEndovascular treatment (EVT) has strong evidence for its effectiveness in treatment of acute ischemic stroke (AIS); however, up to half of the patients who undergo EVT still do not have good functional outcomes. Various prethrombectomy radiological factors have been shown to be associated with good clinical outcomes and may be the key to better functional outcomes, reduced complications, and reduced mortality. In this paper, we reviewed the current literature on these imaging parameters so they can be employed to better estimate the probability of procedural success, therefore allowing for more effective ...

Retrograde Angiography to Detect Dropped Thrombus in Mechanical Thrombectomy
CONCLUSIONS: The retrograde angiography to detect dropped thrombus is a technique to detect a dropped thrombus at the balloon-guiding catheter tip and allows us to retrieve it with subsequent mechanical thrombectomy procedures while maintaining the balloon-guiding catheter inflated and it may be useful for reducing the risk of embolization to distal territory/embolization to new territory.PMID:34704511 | DOI:10.1177/15910199211052726
