Median Arcuate Ligament Syndrome (MALS)

Posted by Kari Ulrich, Alumna Mentor @kariulrich, Dec 26, 2016

I am looking for other patients that have been diagnosed with Median Arcuate Ligament Syndrome. Although it is caused by compression of the celiac artery many people experience abdominal pain after eating, diarrhea, food avoidance. Usually the first doctors they see are GI doctors. It is a diagnosis that is made after everything else is ruled out. I am curious if anyone else has had surgery?

Interested in more discussions like this? Go to the Digestive Health Support Group.

I thought I would update here. I ended up having open surgery with Dr. Mallory Meyer in Denver on 3/22. The surgery went well. I haven't had any nausea or stabbing MALS pain since the surgery, although admittedly it's only been a few days. Most of my pain is right along the incision, and of course the horrible gas pain in my shoulder and sides that took until yesterday to calm down. Honestly the gas pain was worse than the incision pain. My biggest problem was the combo of anesthesia and oxycodone which shut my bladder and bowels down completely, so I had to quit oxycodone and get by with gabapentin, tylenol and a heating pad to get over that. Time will tell, but I think Dr. Meyer is someone worth considering for MALS surgery if you think the Dr. Hsu approach is best (she has studied his approach and is very interested in treating MALS). She believes that nerve involvement is a big part of the symptoms but also cuts back the MAL 4 cm and trims it. Apparently I had a huge mass of inflamed nerve tissue around my celiac artery, which she removed. Of course she is a young surgeon so it was a bit of a risk, but I wasn't willing to wait 4-6 months with my symptoms getting worse and worse.

Hi, I've recently had an MR venograghy done at Mayo in Phoenix. I suffer from several vascular compression syndromes. I had surgery for Nutcracker and SMAS 2 years ago with Dr. Davila . I had a robotic assist lap Left renal vein transposition. I was patient 4 to have it done. I did ok,
symptoms were greatly diminished. I also had Tarlov cysts surgery 9/2020. I have lots of issues (comorbitities due to Ehlers-Danlos)
In October/NovemberI started having some of the symptoms come back.
Pain up under ribs, left side, wrapping around into my back. Sternum pain, short of breath, extreme fatigue, peopleain after eating, loud, painful belching. Nausea. It was intermittent and then has become very frequent.
I notified Dr Davila. He thought perhaps the renal vein had restenosed. He ordered the MR venograghy. I had that done 3/8.
It came back that yes, the renal vein has restenosed and also compression at the celiac plexus.
He had referred me to pain mgmt and ordered the celiac plexus block.
My concern is that Mayo doesn't seem to treat many with MALS.
It took over 40+ years to be diagnosed with Pelvic congestion, Nutcracker, May Thurner, Ehlers-Danlos, mild Chiari Malformation and Tarlov cysts. It was 2+ for Mayo to diagnose me as well.
It was a relief to finally have answers but finding treatment isn't easy. The GI at Mayo told me I didn't have the anatomy for SMAS. After my scan they called to tell me , yes in fact I did have SMAS. I have had all the GI tests more than once.
I live in Az and would be grateful for any insight or suggestions.

I had a consultation at Stanford in Palo Alto California with a vascular surgeon that was not a MALS specialist. She said that the MALS was not causing my symptoms. This was about three years ago. This is when I was trying to figure out if I should have my gallbladder removed. I did end up having my gallbladder removed because she said it would help my symptoms… Unfortunately, nothing has improved… Actually only gotten worse. I did have a phone consultation with Dr.Hsu at Stamford after my gallbladder surgery and he said that my symptoms sounded like MALS and he would be happy to meet with me as he suggested symptoms will get progressively worse.

Just so you know, MALS doesn’t get better on it’s own or by trying different diets, etc. I tried for 16 years before I was totally bedridden and in excruciating pain 24/7. If you have a diagnosis, it’s better to take care of ASAP, as recovery is strenuous especially if you’ve had it causing problems for a while. Dr. Hsu has done over 500 MALS surgeries. But know also, MALS surgery only takes care of MALS pain, which is amazing!

@etr - Great that you will be able to see Dr Hsu. I’m sure it won’t be long then before you’ll have the surgery and relief.
Sorry you lost your gallbladder in the process.
Please post after seeing Dr Hsu! Very exciting.

@etr - You do have a diagnosis of MALS. What now? Consultation with vascular surgeon and possible GI surgeon too. Do you have a major medical center near you? University best.

@lme - To my knowledge, endoscopy and colonoscopy would not show anything that confirms MALS.

@astaingegerdm

@lme It definitely sounds like MALS attacks. Can you tell me what specific tests have been done?

Thank you for the replies! I am scheduled for a colonoscopy and upper endoscopy tomorrow. Is there anything they can look for during these two procedures that might indicate MALS? Otherwise, it sounds like the CT scan (taken on a exhale) is key.

You can definitely have MALS and still be able to eat. I know because I'm one of those cases. I do however get severe stabbing pains and nausea during and after intense exercise. Anything that gets my blood pressure up will do it, as well as sleeping on my right side or sitting too long. It is true that most diagnosed cases present with inability to eat, but it's not exclusive. A lot of what you're describing does sound a lot like SIBO to me though, which I've also had. I've taken rifaximin, got better, and then all the GI symptoms came back. Tried 2 rounds of antimicrobial herbs, stuck to the FODMAP diet, and now a soil-based probiotic and I'm doing much better with that. I'd definitely rule out SIBO because it can be cured without surgery. MALS also can upset GI functioning, because the celiac nerves are also being compressed. Usually that means pain/nausea, but IBS and SIBO symptoms seem to go hand in hand with MALS for a lot of people. It makes me wonder if a celiac plexus nerve block might be a good test for you.

For your sake though, I hope it is not MALS and is something else you can figure out because MALS surgery is no joke. I had my first surgery in 2015 and all they did was release the ligament laparoscopically, only to have symptoms slowly return about 2 years ago. There are multiple theories and approaches to this surgery, so it's all on the patient to research and decide which surgeon and method to trust. I would continue pressing your GI docs or find one with a little more curiosity and compassion, until you reach a clear diagnosis.

Hello… Thank you for your information… I did work with a excellent nutritionist and did the SIBO protocol with antibiotic, herbal, and have been eating low FODMAP for the last three years. I use bitters and or enzymes before I eat a meal. I find that probiotics are a bit hard for me to take so I drink fermented liquid for a probiotic.
Thanks again!

Hello… So I’ve had three CT angiogram’s with and without contrast, abdominal ultrasound, abdominal aorta ultrasound, HIDA scan,gastric emptying transit/motility study, two endoscopy’s and two colonoscopies, EKG, chest x-ray’s, lots of bloodwork

The three CT angiogram‘s confirmed MALS The last report saying “near occlusion versus occlusion of the celiac trunk due to MALS”.When I asked my primary care what that meant he said he didn’t know. He had never heard of MALS.
