Virginia creeper can be quite rampant. It will cling happily to your willow screen and will probably grow though it as well. When you come to prune your creeper ( as you surely will ), the willow screen will be difficult to free from the creeper.
Either plant something more "gentle" - such as a Clematis but not Montana - or use the screen as a backdrop for some tall planting .
I imagine how soon you need to replace the screen will depend on the wear and tear it gets.
