Acute Mesenteric Ischemia: A Challenge for the Acute Care Surgeon

Area of Science:

• Gastroenterology
• Vascular Surgery
• Interventional Radiology

Background:

• Acute mesenteric ischemia (AMI) is an uncommon but serious cause of acute abdomen in the elderly.
• High mortality rates (up to 80%) are associated with surgical treatment without revascularization.
• AMI can be more frequent than appendicitis or ruptured abdominal aortic aneurysm in older populations.

Purpose of the Study:

• To summarize essential knowledge for acute care surgeons regarding AMI.
• To emphasize the clinical presentation and management of "acute on chronic" mesenteric ischemia.
• To highlight the importance of early diagnosis and intervention in improving patient outcomes.

Main Methods:

• Review of current literature and clinical guidelines on acute mesenteric ischemia.
• Emphasis on diagnostic modalities, particularly contrast-enhanced computed tomography (CECT).
• Discussion of multidisciplinary treatment approaches involving gastrointestinal surgeons, vascular surgeons, and interventional radiologists.

Main Results:

• Early revascularization can decrease overall mortality by up to 50%.
• Clinical suspicion combined with early CECT is crucial for timely diagnosis.
• Multidisciplinary collaboration is essential for optimal management of AMI.

Conclusions:

• Prompt diagnosis and early revascularization are key to reducing mortality in acute mesenteric ischemia.
• Acute care surgeons must be aware of AMI, including its "acute on chronic" presentation.
• A collaborative approach involving multiple surgical and radiological specialties improves patient outcomes.
