I Was Scheduled For Surgery And Blood Revealed My Platelet

I was scheduled for surgery and blood revealed my platelet function test was running high and surgery was cancelled. I am now seeing a hematologist who is waiting for results of a Von Wilderbrand blood test. I want to now if I have Von Wilderbrand what can be done to correct it or make it possible for me to have the surgery. Also if I don't have it what can be done to my platelet function to lower it to normal levels.
