During/after reperfusion, what is the recommended BP target to avoid rebound hypertension?

Explanation:
After reperfusion, keeping blood pressure within a moderate range helps protect the brain: it prevents dangerous bleeding while still ensuring enough flow to the area that was at risk but can still benefit from recovery. The best target is to keep systolic blood pressure under 180 and diastolic under 105 mmHg. This upper limit reduces the risk of hemorrhagic transformation that can occur when vessels are suddenly reopened, without compromising perfusion to the ischemic penumbra if pressure drops are too aggressive. Lower targets, like 160/90 or 170/95, could reduce cerebral blood flow too much in regions that rely on higher pressures for perfusion. A higher target, such as 190/110, would permit pressures that increase the chance of rebleeding or hemorrhagic complications after reperfusion. So, staying under 180/105 mmHg strikes the needed balance to avoid rebound hypertension while protecting the brain.
