Intracranial large-vessel ischemia is associated with poor clinical outcome and increased mortality. Early reperfusion of ischemic tissue remains the goal of treatment of stroke. Intravenous tissue plasminogen activator (IV tPA) has been shown to improve clinical outcomes for patients who experience ischemic stroke, but it has been shown to be less efficacious for large-vessel occlusions. Mechanical clot extraction provides a therapeutic option for those who are ineligible for, or who do not respond to, conventional ischemic stroke treatment. ⋯ Mechanical clot extraction can be performed safely in patients with large-vessel occlusions, and successful recanalization resulted in better clinical outcomes than those without. Mechanical thrombectomy provides a therapeutic option for ischemic stroke patients who are ineligible for, or who do not respond to, IV thrombolytics. Further studies, including randomized clinical trials, are needed to validate these findings.

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.
