Background: Embolic protection devices may decrease periprocedural thromboembolic complications during carotid angioplasty and stenting (CAS). When using proximal-protection devices (PPDs), protection starts before crossing the lesion. However, in the medical literature, its use is scarcely reported compared with that of distal-protection filters (DPDs). The objective of this study was to compare periprocedure complications, morbidity, and mortality among 287 consecutive cases of CAS performed with PPDs or DPDs.
Purpose: To determine the safety and efficacy of endovascular therapy for the treatment of basilar artery dissection (BAD).
Purpose: Endovascular management with good preservation of the internal carotid artery (ICA) has become the first-line choice for the treatment of direct carotid cavernous fistulas (CCFs). Multiple treatments have been tried with variable success. This article elucidates the effectiveness and safety of embolization with Onyx and coils under transarterial balloon protection.
Background and Purpose: In past years, thrombectomy has become a widely used procedure in interventional neuroradiology for the treatment of acute intracranial occlusions. However, in 10–20% of patients, there are additional occlusions or stenotic lesions of the ipsilateral cervical internal carotid artery. The purpose of this study was to evaluate the feasibility of emergency carotid artery stent placement in combination with intracranial thrombectomy and the clinical outcome of the treated patients.
Background and Purpose: Acute occlusion of the ICA is often associated with poor outcomes and severe neurologic deficits. This study was conducted to evaluate outcome of the occluded ICA and efficacy of recanalization under protective flow arrest.
Background and Purpose: Previous studies have demonstrated that socioeconomic disparities in the treatment of cerebrovascular diseases exist. We studied a large administrative data base to study disparities in the utilization of mechanical thrombectomy for acute ischemic stroke.
Background and Purpose: The clinical impact of facet joint bone scan activity is not fully understood. The hypothesis of this study is that facet joints targeted for percutaneous treatment in clinical practice differ from those with reported activity on technetium Tc99m methylene diphosphonate SPECT/CT.
Background and Purpose: The infarctions arising in the long insular arteries of the M2 segment have been poorly described in the past. The purpose of this study was to investigate the incidence, clinical characteristics, and pathogenesis of long insular artery infarcts.
Background and Purpose: CT angiography, CT perfusion, and MR imaging have all been advocated as potentially useful in treatment planning for patients with acute ischemic stroke. We evaluated a large multihospital data base to determine how the use of advanced imaging is evolving in patients treated with intravenous thrombolysis.
Background and Purpose: Acute vertebrobasilar occlusion is an ominous disease with few proved effective treatments. Experience with stent retrievers is scarce and limited to combined therapies (stent retrievers associated with previous intravenous fibrinolysis, intra-arterial thrombolysis, or other mechanical devices). We present our experience with 18 patients treated with direct thrombectomy by using stent retrievers.
Background and Purpose: Stent-retriever devices play an increasing role in the interventional treatment of acute stroke patients, because fast recanalization can be achieved. The purpose of this study was to evaluate the feasibility of stent-retriever recanalization in patients with wake-up stroke in the anterior circulation.
Background and Purpose: The degree of variation in retreatment decisions for residual or recurrent aneurysms among endovascular therapists remains poorly defined. We performed a multireader study to determine what reader and patient variables contribute to this variation.
Background and Purpose: Patient age substantially influences treatment decisions for ruptured cerebral aneurysms. It would be useful to understand national age-related trends of treatment techniques and outcomes in patients treated for ruptured cerebral aneurysm in the United States.
Introduction: Uric acid is an antioxidant with neuroprotective effects in experimental models of stroke. We assessed whether uric acid therapy would improve functional outcomes at 90 days in patients with acute ischaemic stroke.
Background and Purpose: We aimed to evaluate the procedural safety, clinical, and angiographic outcome of carotid angioplasty and stenting for high-grade (≥70%) radiation-induced carotid stenosis (RIS) using atherosclerotic stenosis (AS) as a control.
