This study is testing two methods to treat a type of stroke caused by a blockage in the blood vessels in the brain. One way uses a small tube (stent) to keep the blood vessel open, and the other does not. A stroke is when blood flow to the brain is interrupted, causing brain cells to die. The study compares two groups: one gets a stent placed in the neck artery, and the other gets treatment without a stent. The study aims to determine which method works better.

• **Study Duration:** Participants will be followed for 3 months and 1 year after treatment.
• **Compensation:** Details on compensation are not provided in the summary.
• **Risks:** Involves procedures that require FDA-approved devices and follow-up checks.

To join, you must be 18-79 years old, have a certain type of stroke, and not be eligible for some other stroke treatments. Pregnant women and people with certain medical conditions cannot participate. Participants need to be able to consent and start treatment within 16 hours of stroke symptoms. The study uses computers to randomly assign participants to either treatment group.
