What is Median Arcuate Ligament Syndrome (MALS)?

Median arcuate ligament syndrome (MALS) is a disease caused by a band of tissue in the chest region called the median arcuate ligament pulling on the artery delivering blood to the upper abdomen, known as the celiac artery. In some instances, MALS might cause stomach pain.

The positions of the median arcuate ligament and celiac artery vary among individuals. The ligament typically crosses the body's main blood vessel, the aorta, over which lies the celiac artery. However, a misplaced artery or ligament can result in MALS. The ligament may also compress the celiac plexus, the network of nerves that encircles the celiac artery.

MALS can strike anyone, even young ones. There are several names for MALS.

• Celiac artery compression
• Celiac axis syndrome
• Dunbar syndrome

Surgery held as a form of treatment to decompress the ligament and allow blood to flow again through the artery.

What are the symptoms Median arcuate ligament syndromes (MALS)?

The first sign of MALS is an upper abdomen pain that occurs after eating. When you stop eating because of the pain, you lose weight—usually more than 20 pounds—a condition called food aversion. Additional associated symptoms might include:

• Feeling uneasy.
• Diarrhea.
• Collapsing.

The gradual transit of food from the stomach into the small intestine is delayed gastric emptying.

What causes MALS?

The celiac plexus nerves being pinched or compressed by the median arcuate ligament over the celiac artery is thought to be the etiology of MALS. If you have carpal tunnel syndrome, the pain you experience in your hands may be comparable to the agony that these nerves are pinching. Uncertainty surrounds this notion, but another possible cause of the illness could be inadequate blood supply to the organs served by the celiac artery.

What is the diagnosis and tests for MALS?

If your doctor thinks you may have MALS, they will look over your medical history and give you a physical checkup. Your doctor may also request some tests, including as imaging studies and blood tests, to help rule out more frequent causes of your symptoms. These include:

• Illness known as gastroesophageal reflux (GERD).
• Stomach aches.
• Gastroparesis.
• Intestines, liver, gallbladder, spleen, or pancreas issues.

Your doctor may prescribe a mesenteric duplex ultrasound test to check for compression of the celiac plexus and blood flow through the celiac artery after these disorders have been ruled out. A CT or MRI angiography can provide additional useful imaging tests by providing a more detailed image of your aorta and celiac artery.

• These procedures will be carried out if a probable MALS diagnosis has been made after reviewing your records.
• Imaging tests (such a CT/MRI angiography or a mesenteric ultrasonography of the celiac axis) will either be ordered or repeated.
• Surgeons who specialize in vascular surgery or minimally invasive surgery will meet with you.

A pain management professional will assess you in case a celiac plexus block surgery is necessary. This helps to establish the diagnosis and provides momentary respite from the symptoms of MALS.

What are the treatments for MALS?

The only available treatment for MALS is surgery. The treatment that is most frequently performed is known as decompression or release of the median arcuate ligament. Usually, an open procedure is performed. Occasionally, a robotic or laparoscopic minimally invasive procedure can be used.

• Under general anesthesia, a surgeon divides the median arcuate ligament and the network of stomach-area nerves (celiac plexus), resulting in greater space for the artery. This eases nerve pressure and replenishes blood flow.
• For some MALS patients, revascularization the complete restoration of blood flow may need open surgery to replace or repair a blocked celiac artery.

After MALS release surgery, you will typically require two to three days in the hospital. A month or two following the procedure, you will require an ultrasound to verify that the celiac artery's blood flow is totally restored. Even in children with MALS, surgery to release the median arcuate ligament has been demonstrated in several studies to be safe. This can greatly improve the quality of their lives, and they are also very frequently immediately relieved from their pain.

What is a celiac plexus block?

A block may be performed by injections of medication into the celiac plexus to treat abdominal pain.

• You may be given a medicine through a vein to make you feel drowsy or to calm you if you're going to have a celiac plexus block. Lie on your back on an X-ray table- Your doctor numbs an area of skin in your back with a local painkiller. Then a doctor, using X-ray guidance, will:
• A thin needle will be inserted into your back near your spine, and through it, an anesthetic will be given.
• On the other side of your spine, insert a second needle.
• To ensure that the drug reaches the right place, inject dye.
• Inject a steroid, clonidine, or adrenaline to relieve the discomfort. It is also possible to inject phenol or alcohol to kill the nerves.

You can leave the operation the same day, and it often takes less than 30 minutes. You can notice a warming sensation in your abdomen and a decrease in pain.

To maintain the pain relief, you will typically require two to ten shots. Some patients get weeks of pain relief after a celiac plexus block, some people get years of respite, and many people can resume their regular activities.

What kind of aftercare is required after surgery for median arcuate ligament syndrome (MALS)?

To ensure that the median arcuate ligament is not being further compressed, the majority of MALS patients undergo a duplex ultrasound one month following their surgery. Because of accumulated scar tissue, some patients still experience celiac artery constriction. Treatment options for this include non-surgical methods including medication or, in rare cases, another celiac plexus block. Typically, this does not result in complaints following surgery. Other endovascular treatments, including celiac axis stenting, may be required on occasion.

A small group of individuals who experience repeated bouts of MALS may be candidates for a second attempt at scar tissue release. Nonetheless, there is a significantly higher likelihood (more than 50%) that these individuals may need an open surgery (assisted by a vascular surgeon).
