Ethnicity, Race, and Post-Operative Stroke Risk among 53,593 Patients with Asymptomatic Carotid Stenosis Undergoing Revascularization
The incidence of post-operative stroke following carotid endarterectomy is an uncommon event and differences by racial and ethnic subgroups are not fully described in the literature.

Moyamoya vasculopathy in PHACE syndrome: six new cases and review of the literature
PHACE syndrome is a neurocutaneous disorder including posterior fossa malformations, hemangiomas, arterial lesions, cardiac defects, and eye abnormalities. PHACE arteriopathies may be progressive and have been recently categorized based on the risk of acute ischemic stroke, raising attention to the potentially devastating consequences of cerebrovascular complications in this syndrome. On the other hand, the natural history of arteriopathy in PHACE syndrome remains poorly understood. At the moment, there are no established surgical guidelines for high risk vasculopathies, including quasi-moyamoya, in this syndrome.

A Neurosurgical Stratagem: Doing the Same with Less?
We have read and much appreciated the article by Ma et  al.,1 entitled “Endoscopic Evacuation of Basal Ganglia Hematoma: Surgical Technique, Outcome and Learning Curve,” recently published in WORLD NEUROSURGERY, in which the authors describe their experience with evacuation of basal ganglia hematomas through minimally invasive surgery by an endosco pic technique. Intracerebral hemorrhage (ICH) is the most common type of stroke, accounting for up to 15% of all stroke cases. ICH incidence has increased with advanced age, and its prognosis remains poor.

Relationship between clot quality and microguidewire configuration during endovascular thrombectomy for acute ischemic stroke
and Purpose: Although endovascular approaches for acute ischemic stroke have been developed, the appropriate selection and sequence of device application or other treatments is unclear. If information about the clot quality can be obtained before the selection of devices, fast recanalization with a suitable device and strategy can be achieved. We studied the relationship between clot quality and the configuration of a microguidewire during endovascular thrombectomy.

Impact of Smartphone Applications on Timing of Endovascular Therapy for Ischemic Stroke: A Preliminary Study
Metrics of imaging-to-puncture and to-reperfusion were recently found to be associated with clinical outcomes of endovascular thrombectomy for acute ischemic stroke. However, measures for improving workflow within hospitals to achieve better timing results are largely unexplored for endovascular therapy. The aim of this study is to examine our experience with a novel smartphone application developed in-house to improve our timing metrics for endovascular treatment.

Endovascular thrombectomy alone versus combined with intravenous thrombolysis
To date, no randomized trial has directly addressed the question of whether IV tPA (IVT) improves the outcomes of IVT-eligible patients who will eventually undergo endovascular therapy (EVT) or whether a direct EVT strategy will be equally effective. We performed a systematic review and meta-analysis compare the efficacy and safety of direct EVT versus endovascular treatment with intravenous therapy (EVT+IV tPA) in adults with acute ischemic stroke.

First Case of Autonomic Dysrefleixa Following Elective Lower Thoracic Spinal Cord Transection in a Spina Bifida Adult
Spinal cord transection is a radical but effective treatment for highly selective cases of symptomatic spinal re-tethering in paraplegic spina bifida patients. Autonomic dysreflexia (AD) is a potentially life-threatening syndrome involving a dysregulated sympathetic discharge reflex commonly seen following cervical and high thoracic spinal cord injury leading to a disconnect between autonomic pathways above and below the lesion that can lead to severe complications including uncontrolled hypertension, bradycardia, stroke, and potentially death.

In Reply To “Moyamoya Disease: From Hypoperfusion to Network Disruption”
We thank Dr. Lanterna for his thoughtful and constructive comments on our article, which elucidated the theory of moyamoya disease (MMD) networks: from hypoperfusion to network disruption. In our report, we retrospectively reviewed 82 patients (164 hemispheres) with MMD at late Suzuki stage from a single institution in China.1 We concluded that although direct bypass surgery was shown to effectively improve the cerebral perfusion in patients with MMD at late Suzuki stage, compared with conservative treatment, it did not reduce the risk of recurrent stroke.

Moyamoya Disease: From Hypoperfusion to Network Disruption
I read with great interest the article by Ge et  al.1 examining the effectiveness of the superficial temporal artery to the middle cerebral artery (STA-MCA) bypass in patients with moyamoya disease (MMD) at late Suzuki stage. The authors retrospectively reviewed a series of 82 patients with an average follow-up of 55.1 ± 16.2 months. During the follow-up, a stroke event was experienced in 9% of the conservatively treated hemispheres, and in 10% of surgically treated hemispheres. The authors concluded that although the bypass may improve cerebral perfusion, it does not offer significant advantages in terms of stroke preve...

Trans-Anterior Communicating Artery Primary Stenting in Acute Tandem Middle Cerebral Artery –Internal Carotid Artery Occlusion Due to Thoracic Aortic Stent Graft
The main target of stroke intervention is the revascularization of occluded vessels, usually achieved with thrombectomy or thrombus aspiration. Despite good results in limited series, intracranial primary stenting is controversial for increased hemorrhagic risk owing to the need for dual antiplatelet therapy.
