MR angiography (MRA) provides a versatile, radiation-free approach for evaluation of the mesenteric vasculature offering contrast-enhanced and noncontrast techniques tailored to clinical needs. Advances in hardware, pulse sequences, acceleration methods, and contrast agents have improved spatial and…
Pediatric Abdominal Vascular Compression Syndromes: Clinical Presentation, Comorbidities, and Outcomes Following Surgical Correction.
The goal of this case series was to characterize the clinical presentation, comorbidities, and postoperative outcomes of pediatric patients who underwent surgical repair for Median Arcuate Ligament Syndrome (MALS) and/or Nutcracker Syndrome (NCS). We conducted a retrospective chart review of 17 pedi…
Stepwise management of median arcuate ligament syndrome with visceral artery aneurysm: Surgical ligament release followed by percutaneous transluminal angioplasty.
A woman in her 20s presented with an 8-year history of postprandial abdominal pain. Contrast-enhanced computed tomography revealed severe stenosis at the origin of the celiac artery, collateral circulation from the superior mesenteric artery, and an associated inferior pancreaticoduodenal artery ane…
Editorial Comment: When the Ligament Matters: Recognition, Intervention, and the Limits of Current Evidence for Median Arcuate Ligament Compression Management in Pancreaticoduodenectomy.
Vascular Abnormalities in Athletes: State-of-the-Art Multimodality Imaging.
Vascular abnormalities in athletes, although less common than musculoskeletal injuries, present a significant diagnostic challenge due to overlapping manifestations. These conditions range from subtle exertional discomfort to potentially limb-threatening ischemia and life-threatening complications s…
Hypoglycemia associated with median arcuate ligament syndrome surgery.
We present a patient who developed symptomatic hypoglycemia following surgical treatment for median arcuate ligament syndrome (MALS). The patient experienced predominately postprandial hypoglycemia after higher carbohydrate meals. Clinical findings revealed postprandial hyperinsulinemic hypoglycemia…
Duodenal Obstruction and Grade III Acute Cholangitis Following Pancreaticoduodenal Artery Aneurysm Rupture During Conservative Management of Acute Type B Aortic Dissection: A Case Report.
Aneurysms of the pancreaticoduodenal arcade are uncommon visceral artery aneurysms that are strongly associated with stenosis or occlusion of the celiac axis and that may rupture irrespective of size. Rupture produces a peripancreatic or retroperitoneal hematoma, and duodenal stenosis is a recognize…
Anatomical Evaluation of Celiac Artery and Median Arcuate Ligament Displacement During Spinal Corrective Procedures: A Cadaveric Study.
Celiac artery compression syndrome (CACS) is a rare but potentially life-threatening complication of spinal deformity correction. Although prior reports have suggested an association between spinal correction and vascular compression, the underlying anatomical mechanisms remain unclear. This study a…
