Median arcuate ligament syndrome, a rare case of chronic abdominal pain
2018
The median arcuate ligament syndrome (MALS) is a rare disease characterized by abdominal pain caused by the external compression of the celiac artery by the median arcuate ligament. Surgical treatment is indicated, but given the non-specific symptoms, these patients are often hospitalized in the Departments of Internal Medicine where the diagnosis may be unknown. We present a case of MALS admitted to our Internal Medicine Division. An abdominal ultrasound in a woman with longstanding abdominal pain showed elevated celiac artery velocities during forced expiration. Computed tomography angiography (CTA) of the abdomen showed stenosis of the origin of the celiac artery and confirmed the diagno…
Pancreaticoduodenal arteries aneurysms: Evaluation of frequency and association with celiac artery stenosis due to compression by median arcuate liga…
2019
The aim of the study is to evaluate the prevalence of pancreaticoduodenal arteries (PDA) aneurysms in a large population, and to define possible correlations with celiac artery stenosis due to compression by the median arcuate ligament. Radiological reports of abdominal contrast-enhanced CT scans of 18,180 patients were scrutinized to identify patients with true PDA aneurysms. Two abdominal radiologists classified the aneurysms according to size, location and morphology and scored the presence of celiac artery stenosis due to either median arcuate ligament compression or atherosclerotic disease. Eleven true PDA aneurysms were identified in 10 patients. Nine out of 10 patients had stenosis o…
CT imaging findings of abdominopelvic vascular compression syndromes: what the radiologist needs to know.
2020
AbstractAbdominopelvic vascular compression syndromes include a variety of uncommon conditions characterized by either extrinsic compression of blood vessels by adjacent anatomical structures (i.e., median arcuate ligament syndrome, nutcracker syndrome, May-Thurner syndrome) or compression of hollow viscera by adjacent vessels (i.e., superior mesenteric artery syndrome, ureteropelvic junction obstruction, ureteral vascular compression syndromes, portal biliopathy). These syndromes can be unexpectedly diagnosed even in asymptomatic patients and the predisposing anatomic conditions can be incidentally discovered on imaging examinations performed for other indications, or they can manifest wit…

Chronic mesenteric ischaemia is a severe and incapacitating disease, causing complaints of post-prandial pain, fear of eating and weight loss. Even though chronic mesenteric ischaemia may progress to acute mesenteric ischaemia, chronic mesenteric ischaemia remains an underappreciated and undertreated disease entity. Probable explanations are the lack of knowledge and awareness among physicians and the lack of a gold standard diagnostic test. The underappreciation of this disease results in diagnostic delays, underdiagnosis and undertreating of patients with chronic mesenteric ischaemia, potentially resulting in fatal acute mesenteric ischaemia. This guideline provides a comprehensive overvi…
