Endovascular Treatment for Spontaneous bilateral carotid artery dissection with acute ischemic stroke: A Case Report with automated postprocessing CT perfusion findings and Review of the Literature
Acta Neurol Taiwan. 2023 Jun 30;32(2):48-56.ABSTRACTCarotid artery dissection (CAD) is a common cause of stroke, accounting for up to 25% of all ischemic strokes in young and middle-aged patients. CAD should be considered in young patients with unexplained head and neck pain, with or without focal neurological symptoms and signs. While the clinical features may raise suspicion for CAD, the diagnosis is confirmed by its typical neuroimaging findings. Meanwhile, simultaneous spontaneous dissection of the bilateral carotid artery has rarely been reported. We herein describe a clinically challenging case of a simultaneous bila...

Minimally Invasive Intracerebral Hemorrhage Evacuation Improves Pericavity Cerebral Blood Volume
This study aims to quantify blood volume changes in the perihematomal parenchyma and pericavity parenchyma after minimally invasive intracerebral hemorrhage evacuation (MIS for ICH). Thirty-two patients underwent MIS for ICH with pre- and post-operative CT imaging and intraoperative perfusion imaging (DynaCT PBV Neuro, Artis Q, Siemens). The pre-operative and post-operative CT scans were segmented using ITK-SNAP software to calculate hematoma volumes and to delineate the pericavity tissue. Helical CT segmentations were registered to cone beam CT data using elastix software. Mean blood volumes were computed inside subvolume...

Elevated Hypoperfusion Intensity Ratio (HIR) observed in patients with a large vessel occlusion (LVO) presenting in the evening
Circadian variability has been implicated in timing of stroke onset, yet the full impact of underlying biological rhythms on acute stroke perfusion patterns is not known. We aimed to describe the relationship between time of stroke onset and perfusion profiles in patients with large vessel occlusion (LVO).

Stroke recurrence is associated with unfavorable intracranial venous outflow in patients with symptomatic intracranial atherosclerotic large vessel severe stenosis or occlusion
ConclusionFor patients with sICAS-S/O of the anterior circulation, unfavorable intracranial venous outflow is a potential imaging indicator for predicting higher 1-year RCIE risk.

Low-dose vs. standard-dose intravenous alteplase for acute ischemic stroke with unknown time of onset
ConclusionThe effectiveness of low-dose alteplase might be comparable to that of standard-dose alteplase in AIS patients aged <70 years with favorable perfusion-imaging profiles in the unknown or extended time window but not in those aged ≥70 years. Furthermore, low-dose alteplase did not significantly reduce the risk of sICH compared to standard-dose alteplase.

The charlotte large artery occlusion endovascular therapy outcome score compares favorably to the critical area perfusion score for prognostication before basilar thrombectomy
Late window endovascular thrombectomy (EVT) trials enrolled patients presenting with an internal carotid artery (ICA) or proximal middle cerebral artery (MCA) occlusion using computed tomography perfusion (CTP) or magnetic resonance imaging perfusion selection criteria.1,2 Radiographic1 or clinical mismatch2 was required for inclusion in these landmark studies. Although perfusion imaging is not always used for patient selection in early window anterior circulation thrombectomy,3 CTP ischemic core volume is independently associated with functional outcome improvement in the 0-6-hour time window when good endovascular reperfusion is achieved.
