I had celiac artery compression syndrome surgery after the surgery a few weeks later had ct done still showed high grade stenosis of 80 percent?

Specific Study?: Was the study done in inspiration and expiration? Are your symptoms better? Poor blood flow to the GI system is incredibly painful and difficult to live with. If you feel better after surgery, it may just be some inflammation and/or an imaging artifact. If the pain persists, you need further testing with a dye study to look at the artery. Consult an interventional radiologist and your surgeon.
