Utility of Low-Profile Visualized Intraluminal Support Junior Stent as a Rescue Therapy for Treating Ruptured Intracranial Aneurysms During Complicated Coil Embolization.

Background: Coil protrusion occasionally occurs during embolization and can lead to thromboembolic complications. We aimed to evaluate the efficacy of rescue stenting procedures with a low-profile stent system (LVIS Jr.) for treating ruptured intracranial aneurysms during complicated coil embolization.

Solitary intraventricular hemorrhage without subarachnoid hemorrhage due to aneurysmal rupture: a case report.

The presence of primary intraventricular hemorrhage (IVH) without vascular lesion is very rare. We experienced solitary IVH without subarachnoid hemorrhage due to aneurysmal rupture in a 58-year-old man treated with coil embolization, which contributed to his good prognosis. After 33 days of hospitalization, he had mild right hemiplegic symptoms remaining, and he was transferred to a rehabilitation institute for further treatment.

Preliminary Study of Tirofiban Infusion in Coil Embolization of Ruptured Intracranial Aneurysms.

Background: There have been some reports on the use of intra-arterial tirofiban in ruptured intracranial aneurysms, but few studies have reported on the use of 24 h of intravenous tirofiban infusion in patients with subarachnoid hemorrhage.

Objective: To present our experience with intravenous tirofiban infusion, in the form of a monotherapy as well as in addition to intra-arterial tirofiban, as a prophylactic, and as a rescue management for thrombus in patients who have undergone embolization with coils for ruptured intracranial aneurysms.

Methods: Between December 2008 and January 2015, we retrospectively reviewed 249 ruptured intracranial aneurysms that were treated with coiling at our institutions.

Association of Left Atrial Enlargement with Cortical Infarction in Subjects with Patent Foramen Ovale.

Background And Purpose: Left atrial dysfunction has been reported in patients with patent foramen ovale (PFO). Here we investigated the role of left atrial dysfunction in the development of embolic stroke in patients with PFO.

Methods: We identified consecutive patients with embolic stroke of undetermined sources except for PFO (PFO+ESUS).

Pipeline Embolization Device for Large/Giant or Fusiform Aneurysms: An Initial Multi-Center Experience in Korea.

Purpose: The purpose of this study was to assess the safety and early outcomes of the Pipeline device for large/giant or fusiform aneurysms.

Materials And Methods: The Pipeline was implanted in a total of 45 patients (mean age, 58 years; M:F=10:35) with 47 large/giant or fusiform aneurysms. We retrospectively evaluated the characteristics of the treated aneurysms, the periprocedural events, morbidity and mortality, and the early outcomes after Pipeline implantation.

Alternative Detachment Technique for Electrically Detachable Coils: Rescue From an Unintended Complication.

Background: Embolization of intracranial aneurysms with the use of detachable coils has become the most widely used therapy for this condition. However, unexpected device failure can lead to critical complications.

Objective: To describe an alternative detachment technique for various electrically detachable coils (eg, Target of Stryker Neurovascular, Presidio and Microphere of Codman Neurovascular, and MicroPlex and Hydrocoil of MicroVention Terumo) that can be used when standard troubleshooting techniques are not effective and the physician is not able to remove a coil.

Angiographic findings of in-stent intimal hyperplasia after stent-assisted coil embolization: are they permanent findings?

Objective: Stent-assisted coil embolization for the treatment of intracranial aneurysms has been used widely. This study aimed to investigate the effect of stent implantation in the nonatherosclerotic parent artery with cerebral aneurysms. The authors evaluated luminal changes and the related factors following stent-assisted coil embolization.

Adult Moyamoya Disease: A Burden of Intracranial Stenosis in East Asians?

Background: Both Moyamoya disease (MMD) and intracranial atherosclerotic stenosis (ICAS) are more prevalent in Asians than in Westerners. We hypothesized that a substantial proportion of patients with adult-onset MMD were misclassified as having ICAS, which may in part explain the high prevalence of intracranial atherosclerotic stroke in Asians.

Method: We analyzed 352 consecutive patients with ischemic events within the MCA distribution and relevant intracranial arterial stenosis, but no demonstrable carotid or cardiac embolism sources.

Comparison of Enoxaparin and Warfarin for Secondary Prevention of Cancer-Associated Stroke.

Background. The aim of this study was to determine which anticoagulant is superior for secondary prevention of cancer-associated stroke, using changes in D-dimer levels as a biomarker for recurrent thromboembolic events. Methods.

Susceptibility Vessel Sign for Intra-arterial Thrombus in Acute Posterior Cerebral Artery Infarction.

Background: Susceptibility vessel sign (SVS) on susceptibility-weighted imaging (SWI) has a high sensitivity and specificity to detect the intra-arterial thrombus in anterior circulation stroke. However, SVS has not been evaluated in posterior circulation stroke.

Methods: We reviewed the data from patients with acute posterior cerebral artery (PCA) infarction within 24 hours from stroke onset.

Eligibility and preference of new oral anticoagulants in patients with atrial fibrillation: comparison between patients with versus without stroke.

Background And Purpose: Recent randomized clinical trials (RCTs) have evaluated the benefit of new oral anticoagulants in reducing the risk of vascular events and bleeding complications in patients with atrial fibrillation (AF). However, abundant and strict enrollment criteria may limit the validity and applicability of results of RCTs to clinical practice. We estimated the eligibility for participation in RCTs of an unselected group of patients with AF.

Bilateral basal ganglia and unilateral cortical involvement in a diabetic uremic patient.

We report a 57-year-old woman with uremic encephalopathy who presented with dysarthria, dysphagia, hypophonia, and drowsiness. The patient's radiologic findings were rather unusual in that magnetic resonance imaging (MRI) showed abnormal findings involving the basal ganglia bilaterally and frontal cortex unilaterally. After intensified hemodialysis, her symptoms and follow-up brain MRI showed marked improvement.
