Insights

Median arcuate ligament syndrome (MALS) can lead to celiac artery aneurysms. This report details a rare case of MALS with a co-occurring celiac artery aneurysm and dissection, a previously undocumented association.

Area of Science:

  • Vascular Surgery
  • Gastroenterology
  • Medical Case Reports

Background:

  • Median arcuate ligament syndrome (MALS) involves celiac artery compression by the median arcuate ligament.
  • Celiac artery aneurysms are a potential complication of MALS.
  • Arterial dissection is a serious vascular event that can occur in aneurysms.

Observation:

  • This case report describes a patient with diagnosed Median arcuate ligament syndrome.
  • The patient presented with a coincident celiac artery aneurysm.
  • The celiac artery also exhibited dissection.

Findings:

  • This is the first reported case of Median arcuate ligament syndrome associated with both celiac artery aneurysm and dissection.
  • The findings suggest a potential progression pathway from MALS to complex arterial pathology.
  • The co-occurrence highlights the critical need for thorough vascular assessment in MALS patients.

Implications:

  • This case expands the known spectrum of complications associated with Median arcuate ligament syndrome.
  • It underscores the importance of considering dissection in patients with MALS and aneurysms.
  • Further research may elucidate the mechanisms linking MALS, aneurysm formation, and dissection.

Aneurysm I: Introduction01:30

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
