@jhmontrose - After the initial surgery to cut the ligament symptoms returned after 6 months because the celiac artery returned to its compressed condition. A stent was placed. It still works, but is also kinked.
Regarding your upper body pain- ha anyone told you why? Celiac plexus pain? I think Gabapentin will help you.
The body definitely forms collateral blood flow.
CTA now is definitely appropriate now.
I remember when I first met my surgeon he told me that there are quite a few people that have asymptomatic MALS- found at postmortem. I think collateral blood flow must have spared these people from pain.
If there still is compression, bypass surgery should relieve pain- I don’t know about forever!
