Answer: Isn't wisteria amazing! In many cases a vine that has been damaged at the top will sucker like mad from remaining roots over a wide area, in other cases this vigorous grower will simply do that in its natural bent to conquer the world. Usually trimming them off regularly (eg by regular lawnmowing) will stop the sprouts as long as the main top is allowed to grow unfettered. This vine is strong and heavy and requires an extremely sturdy framework for support; it can grow thirty feet long! It can also grow woody and as thick as a man's arm and crush any but the strongest of permanent trelliswork. (My favorite support for it is an unused telephone pole or a large boulder.) It is so beautiful that many gardeners are willing to accomodate it, but caution and planning for its needs are important.
