Enhanced external counter pulsation therapy in patients with symptomatic and severe intracranial steno-occlusive disease: a randomized clinical trial protocol
Intracranial stenosis is prevalent among Asians and constitutes a common cause of cerebral ischemia. While the best medical therapy carries stroke recurrence rates in excess of 10% per year, trials with intracranial stenting have been associated with unacceptable peri-procedural ischemic events. Cerebral ischemic events are strongly related to the severity of intracranial stenosis, which is high in patients with severe intracranial stenosis with poor vasodilatory reserve. Enhanced External Counter Pulsation (EECP) therapy is known to improve myocardial perfusion by facilitating the development of collateral blood vessels i...

Tissue Outcome Prediction in Patients with Proximal Vessel Occlusion and Mechanical Thrombectomy Using Logistic Models
AbstractPerfusion CT is established to aid selection of patients with proximal intracranial vessel occlusion for thrombectomy in the extended time window. Selection is mostly based on simple thresholding of perfusion parameter maps, which, however, does not exploit the full information hidden in the high-dimensional perfusion data. We implemented a multiparametric mass-univariate logistic model to predict tissue outcome based on data from 405 stroke patients with acute proximal vessel occlusion in the anterior circulation who underwent mechanical thrombectomy. Input parameters were acute multimodal CT imaging (perfusion, a...

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...
