Risk factors for long-term disability in transient ischemic attack patients

A transient ischemic attack (TIA) is a temporary blockage of blood to the brain that lasts for less than an hour but doesn't cause any deficits. However, TIA or "mini-stroke" increases the risk of cardiovascular events in the next five years.

tPA administration and venous outflow profile in acute ischemic stroke patients

Study overview and clinical question Good venous outflow (VO) is associated with favorable outcomes and a higher likelihood of reperfusion following endovascular thrombectomy (EVT). Can early tPA administration in acute ischemic stroke patients improve the VO profile in the baseline CTA performed before EVT?

Assessment of cerebral collateral cascade in ischemic stroke patients

Good cerebral collateral circulation is associated with favorable functional outcomes following EVT. Can a comprehensive cerebral collateral cascade (CCC) analysis help predict clinical and radiological outcomes in patients treated with EVT?

Perfusion imaging to select basilar artery occlusion patients eligible for EVT

In the last decade, several randomized clinical trials demonstrated the role of CT perfusion (CTP) in evaluating anterior circulation large vessel occlusion (LVO) patients eligible for endovascular thrombectomy (EVT).

How AI Is Helping Expand Endovascular Thrombectomy Treatment in South America

Portugués | Español The last decade has brought significant advances in imaging technologies and endovascular thrombectomy (EVT) devices used to treat acute ischemic stroke. While many of these advanced technologies are used in stroke centers in resource-rich countries, recent studies in South America are helping to justify adoption in countries that may not have the same care infrastructure.

AI and Pediatric Arterial Ischemic Stroke

A retrospective, observational, clinical cohort study conducted by Melissa J Visser and co-authors showed that it is feasible to use Rapid’s automated perfusion-diffusion imaging software to determine the mismatch characteristics in childhood acute arterial ischemic stroke (AIS).

Rapid Workflow for Stroke mobile app significantly reduces intrahospital treatment times

An analysis of large vessel occlusion (LVO) patient data collected before and after the stroke team’s adoption of the Rapid Workflow for Stroke mobile app at Johns Hopkins University School of Medicine showed a significant reduction in intrahospital treatment times.

Late-window thrombectomy: patient selection at 6 hours

Pooled data confirms benefit of EVT in the late window An analysis of six randomized clinical trials found that patients meeting the DAWN (clinical mismatch) or DEFUSE 3 (target mismatch) imaging profiles experienced significant functional improvement at 90 days when treated with endovascular thrombectomy (EVT) in the 6–24 hour late window.
