What type of follow-up care is needed after median arcuate ligament syndrome surgery?

Most patients have a duplex ultrasound one month after surgery to make sure that there is no further compression of the median arcuate ligament. Some patients continue to have narrowing of the celiac artery because of scar tissue that has built up. This usually does not cause symptoms after surgery and can be treated with non-surgical techniques such as medications or, in rare cases, another celiac plexus block. Occasionally, other endovascular therapies may be needed. A small group of patients who have repeated episodes of MALS may be candidates for a second attempt at the release of the scar tissue. These patients, however, are at much higher risk (greater than 50%) of needing an open operation (with the assistance of a vascular surgeon).
