SEIMLESS: Simultaneous Extracranial, Intracranial Management of (tandem) LESsions in Stroke.

SEIMLESS is an efficient procedural method that simultaneously treats a distal intracranial occlusion and a more proximal one. Our small case controlled study finds that this technique is feasible and can lead to faster intracranial recanalization compared with the standard 'sequential' method, utilizing less contrast and radiation in the process. Larger studies are needed to verify our findings.
