The Gateway balloon-Wingspan stent system is the first, and currently the only "on-label" device for the treatment of symptomatic intracranial stenosis in the United States. In initial single-arm studies, investigators have indicated that this system can be used for the treatment of symptomatic intracranial atherosclerotic disease with high levels of technical success and acceptable periprocedural complication rates, which are comparable with, or better than, those reported for other endovascular techniques. Intermediate- and long-term follow-up data for patients treated with the Wingspan device remain sparse. We critically review the existing data, which characterize the risk profile and efficacy of endovascular interventions for intracranial atherosclerotic disease, as well as the available clinical evidence that could be used to select appropriate patients for treatment.

Review Meta Analysis
Vasospasm after aneurysmal subarachnoid hemorrhage: review of randomized controlled trials and meta-analyses in the literature.
Cerebral vasospasm is a major source of morbidity and mortality following aneurysmal subarachnoid hemorrhage (SAH). A variety of therapies have been utilized to prevent or treat vasospasm. Despite the large number of clinical trials, few randomized controlled trials (RCTs) of sufficient quality have been published. We review the RCTs and meta-analyses in the literature regarding the treatment and prevention of cerebral vasospasm following aneurysmal SAH. ⋯ There are many possible successful treatment options for preventing vasospasm, delayed ischemic neurologic deficits, and poor neurologic outcome following aneurysmal subarachnoid hemorrhage; however, further multicenter RCTs need to be performed to determine if there is a significant benefit from their use. Nimodipine is the only treatment that provided a significant benefit across multiple studies.

Multicenter Study Comparative Study
Determinants of poor outcome after aneurysmal subarachnoid hemorrhage when both clipping and coiling are available: Prospective Registry of Subarachnoid Aneurysms Treatment (PRESAT) in Japan.
To examine current determinants of poor outcome after aneurysmal subarachnoid hemorrhage (SAH) when ruptured aneurysms are treated with either microsurgery (clipping) or endovascular treatment (coiling) depending on each patient's characteristics. ⋯ Introducing an endovascular treatment option has made aneurysm characteristics less important to outcome, but procedural complications are problematic and should be reduced to improve outcome.
