W is affected by spellvamp, though has a diminished effect since it's an AoE/DoT. With 0 Bonus AD and a Hextech Revolver (15% Spellvamp), each enemy hit with her level 5 W will heal her for 4.25 health.

Her Q procs lifesteal for each hit, and the effect is further increased while she's in Dragon Form. Since her Q spreads while in Dragon, every enemy hit will proc her lifesteal.

Lets assume you has a fully stacked Bloodthirster, 100 base AD, and all her enemies have 0 Armor. You now have 200 AD and 25% lifesteal. If you turn into a Dragon, and manage to hit all 5 enemies with her Q, you deal 400 damage with your Q, for a total of 2000 damage since your Dragon Q deals splash. With just that one Q, you just healed 500 health from Lifesteal.
