Introduction: The study attempts to identify notable factors predicting poor outcome, death, and intracranial hemorrhage in patients with acute ischemic stroke undergoing mechanical thrombectomy with stent retriever. These data could be useful to improve the selection of patients for thrombectomy.
Introduction: Permanent vessel sacrifice has become a routine for the management of aneurysms, pseudoaneurysms, tumors, and carotid blowouts. The purpose of this study is to describe a new technique for carotid and vertebral artery sacrifice using a combination of Onyx and coils and to assess its feasibility, safety, and efficacy.
Introduction: Acute stroke from occlusion of the intracranial internal carotid artery (ICA) is associated with a poor clinical outcome despite a thrombolytic treatment. The purpose of this study was to evaluate the outcome of mechanical thrombectomy using the Solitaire stent for the treatment of acute stroke patients with intracranial ICA occlusion.
Introduction: Crossing Y-stent technique is a valid option for coiling wide-necked bifurcation aneurysms. Two main designs of stents, the closed- (CCS) and open-cell (OCS), are used in combination for a crossing Y-construct. This in vitro study was conducted to assess the mechanical characteristics of each stent-combination and to suggest an optimal combination for clinical practice.
Introduction: Systematic computed tomography angiographic (CTA) studies investigating variation in internal carotid artery (ICA) luminal diameters (LDs) are scarce. Knowledge of the normal intra-individual LD variability would provide a cut-off value for detection of more subtle collapses. In addition, low intra-individual variability would allow using contralateral LD as a reference for estimation of stenosis degree in cases where ipsilateral measurement is hampered. Therefore, our aim was to investigate intra-individual LD variation of normal ICA.
Introduction: The impact of targeted embolization of ruptured cerebral arteriovenous malformation (AVM)-associated arterial aneurysms in the acute phase of bleeding is not well known. The objective of our study was to analyze the safety and efficacy of this treatment strategy with special emphasis on its protective effect against rebleeding.
Introduction: Endovascular treatment of ruptured wide-neck bifurcation aneurysms presents a challenge. While still under evaluation, the Woven Endobridge (WEB) aneurysm embolization system has so far shown promising results in the treatment of complex bifurcation aneurysms. We aimed to evaluate the feasibility and short-term follow-up of endovascular treatment of ruptured wide-neck aneurysm with the WEB device.
Introduction: Superselective intra-arterial chemotherapy (IAC) in retinoblastoma has recently become a popular treatment option. In this study, we purposed to investigate the effectiveness of the technique of “retrograde approach through the posterior communicating artery to the ophthalmic artery (OA)” for IAC.
Introduction: Heubner’s recurrent artery (RAH) in brain selective catheter angiograms (digital subtraction angiography, DSA) was evaluated.
Background and Purpose: We aimed to evaluate the predictive value of susceptibility vessel sign (SVS) burden and morphology in middle cerebral artery recanalization.
Background and Purpose: The middle cerebral artery (MCA) bifurcation is a preferred site for aneurysm formation. Wider bifurcation angles have been correlated with increased risk of aneurysm formation. We hypothesized a link between the presence of MCA aneurysms and the angle morphology of the bifurcation.
Background and Purpose: Recanalization rates are higher in acute anterior stroke treated with stent-retrievers when compared with older techniques. However, some still have sizeable infarcts and poor outcome. This may be related to underestimation of core infarct on nonenhanced computed tomography (NECT). CT angiography (CTA) source images (CTASI) and CT perfusion may be more informative. We hypothesize that core infarct estimation with NECT, CTA, and CT perfusion predicts infarct at 24 hours and outcome after fast recanalization.
Background and Purpose: Carotid ultrasound atherosclerosis measurements, including those of the arterial wall and plaque, provide a way to monitor patients at risk of vascular events. Our objective was to examine carotid ultrasound plaque texture measurements and the change in carotid plaque texture during 1 year in patients at risk of events and to compare these with measurements of plaque volume and other risk factors as predictors of vascular events.
Background and Purpose: Several definitions have been proposed to distinguish clinically relevant from incidental cerebral hemorrhagic transformation after thrombolytic therapy for acute ischemic stroke. We investigated which definition best identifies cerebral hemorrhages that alter long-term functional outcome in the National Institute of Neurological Disorders and Stroke (NINDS) tissue-type plasminogen activator (tPA) trials.
Background and Purpose: The aim of the study was to determine the effects of thromboembolism and mechanical thrombectomy on the vessel wall magnetic resonance imaging (VW-MRI) appearance of the intracranial arterial wall.
