A nice way to deter enemies from chasing you is to, as you are running, shift queue a mine along ur path of escape. Enemies will see it and won't want to walk straight over it. They will either run around, giving you more of a lead, or stop chasing you entirely. If they don't it creates an opportunity for a counter gank. This works especially well running thru jungle with more chokes/blindspots.
