Introduction : The grade of reperfusion after endovascular treatment of ischemic stroke e.g. mechanical thrombectomy is determined based on the mTICI score. The mTICI score shows significant interrater variability; it is usually biased towards better reperfusion results if selfassessed by the operator. We therefore developed a semiautomated image p...

... 18% of the patient data received a different score from the algorithm than the neuroradiologists given scores. This can be due to different factors such as; high noisy images (as shown in Figure 4), wrong reference point detection (as illustrated in Figure 5), and large ROI detection (as shown in Figure 6). ...

Objective This clinical note describes a patient who presented with acute basilar artery occlusion and a persistent primitive proatlantal artery. Case Presentation We present the case of an 82‐year‐old woman who presented with sudden onset of left‐sided weakness. Cross‐sectional imaging revealed occlusion of the basilar artery with a persistent pr...

There is ongoing debate concerning the safety and efficacy of various mechanical thrombectomy (MT) approaches for M2 occlusions. We compared these for MT in M2 versus M1 occlusions. Subgroup analyses of different technical approaches within the M2 MT cohort were also performed. Patients were included from the German Stroke Registry (GSR), a multice...

Background: A considerable proportion of acute ischemic stroke patients treated with endovascular thrombectomy (EVT) are dead or severely disabled at 3 months despite successful reperfusion. Ischemic core imaging biomarkers may help to identify patients who are more likely to have a poor outcome after endovascular thrombectomy (EVT) despite success...

Background A thrombus in the M1 segment of the middle cerebral artery (MCA) can occlude this main stem only or extend into the M1-M2 bifurcation. The occlusion pattern may affect endovascular treatment (EVT) success, as a bifurcated thrombus may be more prone to fragmentation during retrieval. Objective To investigate whether bifurcated thrombus p...

Ischemic stroke accounts for over 80% of all strokes and is one of the leading causes of mortality and permanent disability worldwide. Intravenous administration of recombinant tissue plasminogen activator (rt-PA) is an approved treatment strategy for acute ischemic stroke of large arteries within 4.5 h of onset, and mechanical thrombectomy can be...
