ABSTRACT Median arcuate ligament syndrome (MALS) can cause a range of symptoms, including abdominal pain, nausea, vomiting, and weight loss. Because all patients have some degree of celiac artery compression by the median arcuate ligament (MAL), it may be difficult to discern which patients have a pathologic compression. Based on the multiple theories of MALS etiology, it is unlikely that we know the true cause of this syndrome. In fact, there are many physicians who question the validity of the diagnosis of MALS. Before offering intervention for MALS, a thorough gastrointestinal evaluation should be performed, including consideration of diagnostic temporary percutaneous celiac ganglion block. Patients who are on chronic narcotics preoperatively have a lower likelihood of postoperative symptom relief and therefore should be evaluated by a pain specialist preoperatively. The most reliable treatment comprises open surgical treatment with division of the MAL, removal of surrounding celiac ganglion, evaluation of the celiac artery with pressure measurements or ultrasound, and celiac artery reconstruction if indicated. Laparoscopic and endovascular interventions are novel treatments and may be considered in select patients who cannot undergo an open surgical procedure.

    ABSTRACT: INTRODUCTION: The Median Arcuate Ligament Syndrome is a rare condition characterized by postprandial abdominal pain, bowel function disorder and weight loss. We report the first case to our knowledge of Crohn's disease and Median Arcuate Ligament Syndrome. PRESENTATION OF CASE: The patient was a 33 year-old female with a previous diagnosis of Crohn's disease. Acute postprandial abdominal pain affected the patient every day; she was, therefore, referred to US-Doppler and magnetic resonance angiography of the abdominal vessels and received a diagnosis of Median Arcuate Ligament Syndrome. Consequently, the patient was surgically treated, releasing the vascular compression. After the operation, she reported a complete relief from postprandial pain which was one of her major concerns. Subocclusive symptoms occurred after six months due to the inflammatory reactivation of the terminal ileitis. DISCUSSION: The diagnosis of Median Arcuate Ligament Syndrome is mainly based on the exclusion of other intestinal disorders but it should be always confirmed using noninvasive tests such as US-Doppler, angio-CT or magnetic resonance angiography. CONCLUSION: This case demonstrates that the Median Arcuate Ligament Syndrome could be the major cause of symptoms, even in presence of other abdominal disorders.

    ABSTRACT: The aim of this study is to evaluate the effect of body mass index (BMI) on peak systolic velocity (PSV) recording in the celiac artery (CA). Forty male participants were entered prospectively into the study. The subjects were divided into two groups according to their body mass index. Group A included subjects with BMI ≤25 Kg/m(2) and those in group B with BMI >25 Kg/m(2). The diameter and PSV at the origin of CA of subjects in both groups were recorded while the subject positioned in supine and during expiration phase and fasted for 4 hours using duplex ultrasound. Both groups were matched for age and sex. Independent Student's t-test was used to test if there is any statistical significance between diameter and PSV in both groups. Group A's, average age (year, ±SD) was 29.35±1.35 and average BMI (Kg/m(2), ±SD) was 23.1±1.60. Group B's, average age was 30±2.1 and their average BMI was 31±5.1. The average diameter (cm, ±SD) of CA in group A was 0.66±0.076 and in group B was 0.80±0.066. However, the average PSV (cm/s, ±SD) was 117±28.1 in group A and 102±12.4 in group B. Independent student t-test showed statistical significance between both groups for the diameter (p=0.005) and just reached statistical significance for PSV (p=0.049). Subjects with higher BMI showed reduced PSV due to a larger CA diameter and probably due to more fatty tissue accumulation around the CA origin.
