Consensus Statements by Korean Society of Interventional Neuroradiology and Korean Stroke Society: Hyperacute Endovascular Treatment Workflow to Reduce Door-to-Reperfusion Time

Recent clinical trials demonstrated the clinical benefit of endovascular treatment (EVT) in patients with acute ischemic stroke due to large vessel occlusion. These trials confirmed that good outcome after EVT depends on the time interval from symptom onset to reperfusion and that in-hospital delay leads to poor clinical outcome. However, there has been no universally accepted in-hospital workflow and performance benchmark for rapid reperfusion. Additionally, wide variety in workflow for EVT is present between each stroke centers. In this consensus statement, Korean Society of Interventional Neuroradiology and Korean Stroke Society Joint Task Force Team propose a standard workflow to reduce door-to-reperfusion time for stroke patients eligible for EVT. This includes early stroke identification and pre-hospital notification to stroke team of receiving hospital in pre-hospital phase, the transfer of stroke patients from door of the emergency department to computed tomography (CT) room, warming call to neurointervention (NI) team for EVT candidate prior to imaging, NI team preparation in parallel with thrombolysis, direct transportation from CT room to angiography suite following immediate decision of EVT and standardized procedure for rapid reperfusion. Implementation of optimized workflow will improve stroke time process metrics and clinical outcome of the patient treated with EVT.

Performance Rate of Thrombolytic Therapy and Acute Prognosis of Hyperacute Ischemic Stroke

BACKGROUND: Tissue plasminogen activator (tPA) is known to be effective if given within 3 hours after the onset of ischemic stroke. However, no study has been performed regarding what proportion of patients with acute ischemic stroke are actually given tPA within this time window. We therefore tried to figure out the performance rate of thrombolytic therapy and acute prognosis in hyperacute ischemic stroke patients. METHODS: We prospectively registered all the acute ischemic stroke patients. Thrombolyic therapy was decided strictly according to the NINDS tPA protocol and clinical monitoring was done by the NIH Stroke Scale (NIHSS). If tPA was not given, the reason was recorded. RESULTS: Among 613 acute stroke patients during a period of 2.5 years, there were 146 (23.8%) hyperacute ischemic stroke patients within 3 hours after onset. Even in the 29 cases of in-hospital stroke, the rate of early detection and management was only 27.6% (8 cases). Among the hyperacute stroke population, 56 (38.4%) patients were treated with the thrombolytic agent and 27 patients showed positive responses. Thrombolytic therapy was not tried in the remaining 90 patients. The most common reason was expectation of favorable outcome without thrombolysis. But among these patients, subsequent neurological worsening was noticed in 9 patients, particularly in those with vertebrobasilar stroke. CONCLUSIONS: Urgent notice and management of ischemic stroke needs to be more emphasized not only to the general public, but also to medical personnel. More close observation is especially needed in vertebrobasilar stroke cases (J Korean Neurol Assoc 19(5):447~451, 2001)
