Stroke is the third leading cause of death in the USA, Canada, Europe, and Japan. According to the American Heart Association and the American Stroke Association, there are now 750,000 new strokes that occur each year, resulting in 200,000 deaths, or 1 of every 16 deaths, per year in the USA alone. Endovascular therapy for patients with acute ischemic stroke is an area of intense investigation. The American Stroke Association has given a qualified endorsement of intra-arterial thrombolysis in selected patients. Intra-arterial thrombolysis has been studied in two randomized trials and numerous case series. Although two devices have been granted FDA approval with an indication for mechanical stroke thrombectomy, none of these thrombectomy devices has demonstrated efficacy for the improvement of patient outcomes. The purpose of the present document is to define what constitutes adequate training to perform neuroendovascular procedures in patients with acute ischemic stroke and what performance standards should be adopted to assess outcomes. These guidelines have been written and approved by multiple neuroscience societies which historically have been directly involved in the medical, surgical and endovascular care of patients with acute stroke. The participating member organizations of the Neurovascular Coalition involved in the writing and endorsement of this document are the Society of NeuroInterventional Surgery, the American Academy of Neurology, the American Association of Neurological Surgeons/Congress of Neurological Surgeons Cerebrovascular Section, and the Society of Vascular & Interventional Neurology.
"In 2004, the FDA cleared the use of the first clot retrieval device, the MERCI retriever, for thrombectomy in acute ischemic stroke up to 8 h after symptom onset (1). A variety of modalities have been adapted for intracranial thrombectomy including corkscrew retrieval devices, aspiration thrombectomy, and stent retrievers. "
[Show abstract][Hide abstract] ABSTRACT: In the 10 years since the FDA first cleared the use of endovascular devices for the treatment of acute stroke, definitive evidence that such therapy improves outcomes remains lacking. The decision to intubate patients undergoing stroke thrombectomy impacts multiple variables that may influence outcomes after stroke. Three main areas where intubation may deleteriously affect acute stroke management include the introduction of delays in revascularization, fluctuations in peri-procedural blood pressure, and hypocapnia, resulting in cerebral vasoconstriction. In this mini-review, we discuss the evidence supporting these limitations of intubation during stroke thrombectomy and encourage neurohospitalists, neurocritical care specialists, and neurointerventionalists to carefully consider the decision to intubate during thrombectomy and provide strategies to avoid potential complications associated with its use in acute stroke.

"A task force team (TFT) was organized in August 2010 to develop training programs and certification. TFT members conducted research on programs and systems in other countries1,2,3,4,5,6,8,9,10,11,12,13,14,15,16,17,18,19,20,21) and conceptualized the programs that would best suit Korea. After 1 year of effort, a rough draft of the ENS training and certification regulations was prepared, and the standard training program title was decided. "
[Show abstract][Hide abstract] ABSTRACT: The need for standard endovascular neurosurgical (ENS) training programs and certification in Korea cannot be overlooked due to the increasing number of ENS specialists and the expanding ENS field. The Society of Korean Endovascular Neurosurgeons (SKEN) Certification Committee has prepared training programs and certification since 2010, and the first certificates were issued in 2013. A task force team (TFT) was organized in August 2010 to develop training programs and certification. TFT members researched programs and systems in other countries to develop a program that best suited Korea. After 2 years, a rough draft of the ENS training and certification regulations were prepared, and the standard training program title was decided. The SKEN Certification Committee made an official announcement about the certification program in March 2013. The final certification regulations comprised three major parts: certified endovascular neurosurgeons (EN), certified ENS institutions, and certified ENS training institutions. Applications have been evaluated and the results were announced in June 2013 as follows: 126 members received EN certification and 55 hospitals became ENS-certified institutions. The SKEN has established standard ENS training programs together with a certification system, and it is expected that they will advance the field of ENS to enhance public health and safety in Korea.

"Stroke is the third most common cause of death and the most leading cause of disability in the United States.[1–5] Annually, 750,000 new cases are recorded with 150,000-200,000 deaths.[2–4] 80% of all strokes are ischemic and the remindersare hemorrhagic including subarcnoide hemorrhage. "
[Show abstract][Hide abstract] ABSTRACT: Ischemic brain strokes consisttwo-thirdsof strokesand their complications bear a lot of disability for patient and society. In this study, we seek for effect of Erythropoietin on ischemic brain stroke's outcomes according to National Institutes of Health Stroke Scale (NIHSS) changes.
This study is a RCT (randomized clinical trial). All patients with focal neurologic deficit with primary suspicion of brain stroke undergone neuroimaging evaluations. After confirmation of new ischemic brain stroke, the patients with inclusion criteria'srandomized into two groups of cases and controls. NIHSS was defined for each patient and all patients received a routine treatment protocol. Erythropoietin 16,000 IU as a bolus intravenous dose was given to case patients as soon as neuroimaging study confirmed new ischemic stroke and continued as 8000 IU each 12 h up to total dose of 56,000 IU during 3 days. Patients re-evaluated at days 14 and 28 and NIHSS was assessed by another neurologist blinded to patient's group. Finally, NIHSS changes of both groups compared with each other's.
Evaluations revealed that in days14 and 28 during follow-up, Erythropoietin was effective in NIHSS (P= 0.0001). This effect was of value in level of consciousness Commands (P= 0.024), facial palsy (P= 0.003), motor arm (P= 0.0001), motor leg (P= 0.0001), sensory (P= 0.009), and best language (P= 0.023).
Administration of high-dose erythropoietin in first 24 h can be effective on reduction of ischemic stroke complication. A larger scale clinical trial is warranted.
