Background and Purpose: Antiplatelet resistance is known to be associated with symptomatic ischemic complication after endovascular coil embolization. The purpose of our study was to evaluate the relationship between antiplatelet resistance and clinically silent thromboembolic complications using DWI in patients who underwent coil embolization for unruptured intracranial aneurysm.
Background and Purpose: Anterior communicating artery aneurysms account for one-fourth of all intracranial aneurysms and frequently occur in the context of A1 vessel asymmetry. The purpose of this study was to correlate circle of Willis anatomic variation association to angiographic and clinical outcomes of anterior communicating aneurysm coiling.
Background: Three major processes, constrictive vessel remodeling, intimal hyperplasia (IH), and retarded re-endothelialization, contribute to restenosis after vascular reconstructions. Clinically used drugs inhibit IH but delay re-endothelialization and also cause constrictive remodeling. Here we have examined halofuginone, an herbal derivative, for its beneficial effects on vessel remodeling and differential inhibition of IH versus re-endothelialization.
The purpose of this retrospective observational study was to demonstrate the efficacy of a percutaneous screws system in the treatment of lumbar pain caused by high-level disc degeneration combined with facet joint hypertrophy and canal stenosis especially in the L5–S1 levels.
The purpose of our study was to evaluate the technical feasibility of the combination involving percutaneous screw fixation and vertebroplasty in split fractures of thoracolumbar spine.
To study the relationship between intracranial thrombus length and number of stent retrievals, revascularization rates, and functional outcomes in stroke.
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.
