BACKGROUND: The average life expectancy is increasing worldwide, surpassing 80 years in some countries. Recently, mechanical thrombectomy (MT) using modern devices and techniques has led to improved clinical outcomes following acute ischemic stroke. However, thus far, it remains uncertain whether MT is effective in elderly patients aged over 80 years. METHODS: Between July 2013 and June 2016, 207 patients with acute ischemic stroke in the anterior circulation received MT at our center...

Stenting and balloon angioplasty, along with mechanical thrombectomy, have gained notability as adjunctive treatment options to intravenous tissue plasminogen activator (IV-tPA) for tandem internal carotid artery (ICA) and middle cerebral artery (MCA) occlusions (TIM occlusions). Acute ischemic strokes (AISs) secondary to TIM occlusions are associated with poor patient outcomes primarily due to low recanalization rates following intravenous thrombolysis, consequently prompting the need for more invasive recanalization efforts...

J David Spence
Recent advances in secondary stroke prevention include new evidence in hypertension, nutrition, anticoagulation, antiplatelet therapy, intracranial stenosis, percutaneous closure of patent foramen ovale, and lipid-lowering therapy. Individualized therapy for hypertension based on phenotyping with plasma renin and aldosterone markedly improves blood pressure control in patients with resistant hypertension. A Mediterranean diet can reduce the risk of stroke by nearly half. The diagnosis and treatment of metabolic vitamin B12 deficiency, and B vitamins to lower homocysteine, can reduce the risk of stroke by approximately 30%...

INTRODUCTION: Dural venous sinus stenosis (DVSS) may lead to increased intracranial pressure, sometimes requiring a stent if a high pressure gradient exists. Many neuroendovascular physicians use microcatheters to measure gradients, yet there are no studies comparing the accuracies and precisions of modern day microcatheters. We examined pressure recordings from five commonly used microcatheters in an experimental DVSS model. METHODS: Using a programmable pump, dynamic flow was established in a closed circuit mimicking the venous sinus waveform...

Background Thromboembolic complications after stenting of intracranial aneurysms may be affected by antiplatelet administration. Aims This retrospective study aimed to assess the safety of intravenous tirofiban versus loading dose of oral clopidogrel for preventing thromboembolism in stent-assisted coiling of intracranial aneurysms. Methods From January 2006 to December 2013, 281 patients with cerebral aneurysms were treated with stent-coiling using two antiplatelet strategies in comparison: the initial strategy (a loading dose of ≥300 mg clopidogrel followed by dual antiplatelet, clopidogrel group) and the modified strategy (intravenous administration of tirofiban 8 µg/kg over 3 min followed by a maintenance dose of 0...

BACKGROUND: The endovascular technique has been recommended over the past few years to extracranial carotid dissection and pseudoaneurysm with promising results, specially after medical therapy failure. Flow-diverting stents are an alternative for complex cases. These stents have proven to be effective treatment devices for intracranial aneurysms. OBJECTIVE: To find out all cases of flow-diverting stents in the treatment of extracranial carotid dissection with or without pseudoaneurysm and compare to our case report...

PURPOSE: No reliable imaging sign predicting cerebral hyperperfusion after intracranial arterial stenting (IAS) had been described in the literature. This study evaluated the effect of fluid-attenuated inversion recovery vascular hyperintensities (FVHs), also called hyperintense vessel sign on T2-weighted fluid-attenuated inversion recovery (T2-FLAIR) MR images, in predicting significant increase in cerebral blood flow (CBF) defined by arterial spin labeling (ASL) after IAS. METHODS: We reviewed ASL CBF images and T2-FLAIR MR images before (D0), 1 day after (D1), and 3 days after (D3) IAS of 16 patients...

BACKGROUND AND PURPOSE: Since the SAMMPRIS trial (Stenting and Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis), aggressive medical management (AMM), which includes dual antiplatelet therapy (DAPT) and high-dose statin (HDS) therapy, is recommended for patients with symptomatic intracranial atherosclerotic disease. However, limited data on the real-world application of this regimen exist. We hypothesized that recurrent stroke risk among patients treated with AMM is similar to the medical arm of the SAMMPRIS cohort...

Symptomatic carotid artery disease is a significant cause of ischemic stroke, and these patients are at high risk for recurrent vascular events. Patients with symptoms of stroke or transient ischemic attack attributable to a significantly stenotic vessel (70-99% luminal narrowing) should be treated with intensive medical therapy. Intensive medical therapy is a combination of pharmacologic and lifestyle interventions consistent with best-known practices as follows: initiation of antiplatelet agent or anticoagulation if medically indicated, high potency statin medication, blood pressure control with goal blood pressure of greater than 140/90, Mediterranean-style diet, exercise, and smoking cessation...

Traumatic cerebrovascular injury (TCVI) is an uncommon clinical entity in traumatic brain injury (TBI), yet it may cause devastating brain injury with high morbidity and mortality. Early recognition and prioritized strategic treatment are of paramount importance. A total of 1966 TBI patients admitted between 1999 and 2015 in our tertiary critical care center were reviewed. Screening of TCVI was based on the Guidelines for the Management of Severe Head Injury in Japan. TCVI was confirmed in 33 (1.7%) patients; 29 blunt and 4 penetrating injuries...

We report a patient with an important scenario that may arise in the management of an acute ischemic stroke: the need for a repeated mechanical thrombectomy in the same intracranial artery segment. The patient had a history of atrial fibrillation and a mechanical mitral valve replacement. In her first stroke, she had an occlusion of the proximal segment of the right middle cerebral artery; 58 days later, she presented with an occlusion in the same segment of that cerebral artery. In both instances, the thrombus was extracted by a stent retriever with good clinical and radiographic results...

Several medications have been used perioperatively in patients undergoing noncardiac surgery in an attempt to improve outcomes. Antiplatelet therapy for primary prevention of cardiovascular events should generally be discontinued seven to 10 days before surgery to avoid increasing the risk of bleeding, unless the risk of a major adverse cardiac event exceeds the risk of bleeding. Antiplatelet therapy for secondary prevention should be continued perioperatively, except before procedures with very high bleeding risk, such as intracranial procedures...

The experience in the management of thromboembolic complications of distal vessels during coil embolization using stent-retrievers in the setting of subarachnoid hemorrhage (SAH) is still limited. We report a case of 58-year-old woman with a ruptured small anterior communicating aneurysm who experienced during coil embolization a thromboembolic occlusion of the upper post-bifurcation branch of the middle cerebral artery. Mechanical thrombectomy with a stent-retriever (Solitaire, Covidien, Neurovascular) resulted in complete recanalization of the occluded branch with no ischemic complication...
