Chronic mesenteric ischemia, a rare cause of abdominal pain, often results from atherosclerosis. Early diagnosis and intervention are crucial to prevent severe complications and improve patient outcomes.

Area of Science:

  • Vascular Surgery
  • Gastroenterology
  • Radiology

Background:

  • Chronic mesenteric ischemia (CMI) is an uncommon but significant cause of abdominal pain, accounting for 5% of intestinal ischemic events.
  • Atherosclerotic occlusion or stenosis of splanchnic arteries is the most frequent etiology, leading to collateral vascular formation.
  • Symptoms manifest when at least two of the three major splanchnic vessels are compromised.

Purpose of the Study:

  • To review the clinical features, diagnostic modalities, and therapeutic options for chronic mesenteric ischemia.
  • To emphasize the importance of early recognition and intervention in managing this condition.

Main Methods:

  • Review of noninvasive diagnostic methods including computerised axial tomographic angiography (CCTA), magnetic resonance angiography (MRA), and duplex ultrasonography.

  • Inclusion of invasive catheter angiography as a diagnostic tool.
  • Discussion of therapeutic alternatives such as embolectomy, thrombolysis, and percutaneous angioplasty with stenting.

    • Main Results:

    • Intestinal angina, weight loss, and sitophobia are characteristic clinical presentations.
    • Noninvasive and invasive imaging techniques aid in diagnosis.
    • Treatment strategies vary based on disease extent and location, with endovascular interventions gaining prominence.

    Conclusions:

    • CMI, though rare, can lead to debilitating symptoms and potentially life-threatening acute mesenteric ischemia.
    • Prompt diagnosis and management are vital for preventing bowel infarction and mortality.
    • Significant asymptomatic mesenteric vascular disease carries an 86% risk of symptom development and a 40% mortality rate.
