Early diagnosis of acute mesenteric ischemia is crucial for improving patient outcomes, despite its challenging presentation and high mortality rates. Angiography remains essential for timely diagnosis when this condition is suspected.

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Emergency Medicine

Background:

  • Acute mesenteric ischemia (AMI) encompasses arterial occlusion, venous thrombosis, and non-occlusive forms.
  • Despite diagnostic advancements, AMI retains a mortality rate exceeding 60%, highlighting its clinical challenge.
  • Early diagnosis is paramount for improved outcomes but is often hindered by non-specific symptoms.

Purpose of the Study:

  • To emphasize the critical need for early diagnosis in acute mesenteric ischemia.
  • To review diagnostic challenges and current diagnostic standards for AMI.
  • To outline treatment strategies based on AMI classification.

Main Methods:

  • Review of pathophysiology, diagnostic techniques, and clinical presentations of AMI.

  • Emphasis on the diagnostic role of angiography in suspected cases.
  • Discussion of treatment modalities for different subsets of AMI.

    • Main Results:

    • Clinical presentation often features a discrepancy between severe pain and physical findings.
    • No current non-invasive tests offer sufficient sensitivity and specificity for AMI diagnosis.
    • Angiography is the gold standard for diagnosing AMI and should be performed promptly.

    Conclusions:

    • Early diagnosis of acute mesenteric ischemia is critical for reducing high mortality rates.
    • Angiography remains the cornerstone for diagnosing AMI when clinically suspected.
    • Treatment varies, with surgery for obstructive arterial and venous thrombosis, and vasodilation for non-occlusive AMI.
