Left Verterbal Artery Brain Stent

12 years ago on 8/14/2014 I had surgery to put a stent in my left verterbal artery due to a fusal form aneurysm. Even thought I have a small leakage, I have done very well. As I recall, my Surgeon, Dr. Frank Tong at Emory Hospital in Atlanta, GA told me I was number 200 with this new type of stent. My question to anyone who has had this type of surgery, do you still have headaches, especially when the barometric pressure changes?
