Dx'd w/medial arcuate ligament syndrme via ct, us, and angiography shows decrease blood flow in celiac artery, backflow of blood in mesenteric artery.could this be cause of abd pain, nausea after eating?might surgery help?

MALS: Median arcuate ligament syndrome certainly could be the cause of your pain, and surgery could help, but you have to exercise a lot of caution here. It is what we call a diagnosis of exclusion, which means that we have no way to prove that it is the cause of your pain. I always recommend before undergoing surgery that you have a second opinion at a major university gastroenterology department.
