Select Late will be looking at treatment outcomes in patients presenting with severe blood clot blocking a blood vessel in your brain (ischemic stroke) specifically in one of the large arteries in the brain effecting the front of the brain presenting between 24 and 72 hours after stroke start. The study will be looking at patient outcomes when treated with the standard of care medical management compared to medical management plus endovascular thrombectomy (a surgical procedure to remove a blood clot).

This study aims to establish the best clinical practice for the management of acute ischemic stroke related to narrowing or blockage of the neck vessels. Currently, the treating physicians use one of two surgical approaches based on their preference. However, we do not know which technique is the best. In this study, you will undergo mechanical thrombectomy using one of the techniques (stenting vs. non-stenting approaches) to determine which technique is better compared to the other.
