Intracranial stenosis is prevalent among Asians and constitute a common cause of cerebral ischemia. While the best medical therapy carries stroke recurrence rates in access of 10% per year, intracranial stenting was associated with unacceptable peri-procedural ischemic events. Cerebral ischemic events are strongly related to the severity of intracranial stenosis, being 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 in the heart. The investigators hypothesize that EECP therapy may be useful in patients with severe stenosis of intracranial internal carotid (ICA) or middle cerebral artery (MCA).
In patients undergoing planned surgery for carotid tromendarterendectomy, a non-invasive device that registers heart rate variability is attached. Furthermore a non-invasive device that monitors cerebral oxygenation- near infrared spectroscopy as well as electroencephalography is also attached. At times when surgeons clamps the carotid artery, there will be a moment with controlled cerebral ischemia. This will be registered by the devices. The information obtained will be used to teach artificial intelligence what patterns are related to cerebral ischemia. The same procedure will be performed in patients undergoing ocklusive cerebral trombectomy, so the artificial intelligence will learn to recognize cerebral reperfusion.Blood samples will be drawn before and after cerebral ischemia may occur and will be analyzed for neurobiomarkers and cardiac biomarkers. To teach the algorithm patterns from anaesthesia and surgery in patients without pre existing neuronal injury, the same method will be applied to patients undergoing mixed abdominal surgery. This group will provide a better knowledge of neuro biomarker patterns during anesthesia and surgery.
The aim of this study is to evaluate the clinical feasibility of the angiographic Flat Detector CT perfusion imaging (6s PBV) technique. The investigators will examine the specific vessel distribution of patients with steno-occlusive disease, treated with a surgical extracranial-intracranial bypass and assess the cerebral perfusion during test occlusion upon a neurovascular treatment and in intracranial tumor patients referred for potential pre-operative embolization. This study encompasses three scientific objectives: 1. What is the selective contribution of an individual bypass artery to the brain perfusion? 2. Is a selective intra-arterial angiographic perfusion examination useful in the decision-making of performing pre-operative embolization of intracranial tumors? 3. What is the usefulness of performing additive 6s PBV images compared to classical 2D angiography and/or clinical neurological evaluation in case of test occlusion in the evaluation of possible mother vessel occlusion in treatment of complex neurovascular diseases?
This is an initial Phase1/2 dose-finding, randomized, multi-center study to evaluate the safety and tolerability of NCS-01 in patients with acute ischemic stroke. All patients will be randomized within 48 hours of stroke onset. This study will be conducted in 2 stages.
The purpose of this study is to determine whether DEB is not inferior to common bare metal stent using under in long-term vessel patency and inhibiting restenosis in Vertebral Artery Ostium Stenosis
This study aims to build a database for patients with acute ischemic stroke who receive endovascular therapy and analyze the current situation, effectiveness, safety and cost-effectiveness of endovascular therapy for acute ischemic stroke in China.
The investigators aim to determine if dry needling technique in a non myofascial trigger point area generate the same changes in spasticity, function and pain responses as with dry needling in a myofascial trigger point area.
This study is being conducted to evaluate the potential therapeutic role of hyperoxia when applied in the immediate ischemic period following a stroke in the controlled Emergency Department setting. The study will evaluate the effects of hyperoxia in stroke patients on the production of markers of free radical damage and inflammatory markers associated with hyperoxic lung injury.
