Endovascular management of extracranial occlusions at the hyperacute phase of stroke with tandem occlusions
ConclusionsCervical occlusion with coils and thrombectomy with stent-retrievers may be relevant to prevent early embolic recurrence in cervical occlusions with intraluminal thrombus. Stent-retrievers should be further assessed as a first-line approach, since delayed stroke may occur following occlusion with coils. Medical treatment alone may be sufficient when no cervical intraluminal thrombus is present, the Willis polygon is effective, and the cervical occlusion can be crossed easily to perform the intracranial thrombectomy.

Mobile Stroke Unit Reduces Time to Image Acquisition and Reporting INTERVENTIONAL
SUMMARY: Timely administration of thrombolytic therapy is critical to maximizing the likelihood of favorable outcomes in patients with acute ischemic stroke. Although emergency medical service activation overall improves the timeliness of acute stroke treatment, the time from emergency medical service dispatch to hospital arrival unavoidably decreases the timeliness of thrombolytic administration. Our mobile stroke unit, a new-generation ambulance with on-board CT scanning capability, reduces key imaging time metrics and facilitates in-the-field delivery of IV thrombolytic therapy.

Gadolinium to the rescue for mechanical thrombectomy in acute ischemic stroke.
CONCLUSION: Gadolinium-based contrast agents could be effective alternatives for cerebral DSA in patients undergoing mechanical thrombectomy for AIS who have a history of anaphylactic reaction to ICs. PMID: 30567455 [PubMed - as supplied by publisher]

Endovascular Thrombectomy of Calcified Emboli in Acute Ischemic Stroke: A Multicenter Study INTERVENTIONAL
CONCLUSIONS: Acute ischemic stroke with large-vessel occlusion due to calcified emboli is a rare entity in patients undergoing thrombectomy, with considerably worse angiographic outcome and a higher mortality compared with patients with noncalcified thrombi. Good functional recovery at 3 months can still be achieved in about a quarter of patients.

White Matter Disease and Outcomes of Mechanical Thrombectomy for Acute Ischemic Stroke INTERVENTIONAL
CONCLUSIONS: Moderate-to-severe white matter disease is associated with worse outcomes in patients undergoing endovascular treatment without a significant increase in hemorrhagic complications. Studies comparing patients with and without endovascular treatment are necessary to determine whether the benefit of endovascular treatment is attenuated with greater white matter disease.

Deep medullary vein engorgement and superficial medullary vein engorgement: two patterns of perinatal venous stroke
AbstractPerinatal venous stroke has classically been attributed to cerebral sinovenous thrombosis with resultant congestion or thrombosis of the small veins draining the cerebrum. Advances in brain MRI, in particular susceptibility-weighted imaging, have enabled the visualization of the engorged small intracerebral veins, and the spectrum of perinatal venous stroke has expanded to include isolated congestion or thrombosis of the deep medullary veins and the superficial intracerebral veins. Congestion or thrombosis of the deep medullary veins or the superficial intracerebral veins can result in vasogenic edema, cytotoxic ed...

Magnetic resonance imaging quantitative T2* mapping to predict the red blood cell content of in vivo thrombi retrieved from patients with large vessel occlusions in acute ischemic stroke
CONCLUSION: Our study shows that a shorter thrombus-T2* relaxation time is related to a higher red blood cell content within in vivo thrombi.PMID:34559000 | DOI:10.1177/15910199211042473
