First, they sutured the Dura closed (http://en.wikipedia.org/wiki/Dura_mater), which they've done before. This time they will try to reduce the spinal fluid pressure so that it isn't constantly flowing out the ruptured area. A drain at the base of her spine was placed so that over the next 5 days, as she lies on her back, they can drain out 5-10 cc's of fluid per hour. YES, I said 5 days on her back in bed, crappy! The amount they'll drain is the same amount that her body is producing. The plan is that the compromised area will then have a chance to heal without being constantly forced open from the pressure of the escaping fluid.
