Tricky acute mesenteric ischemia: what can we do?

Area of Science:

• Vascular Surgery
• Gastroenterology
• Emergency Medicine

Background:

• Acute mesenteric ischemia (AMI) presents significant morbidity and mortality.
• High index of suspicion is crucial for patients with severe abdominal pain disproportionate to findings, especially those with atrial fibrillation or vasoconstrictor use.

Purpose of the Study:

• To review current evidence on AMI pathophysiology, risk factors, and diagnostic-therapeutic advancements.
• To emphasize optimizing clinical decision-making in managing this critical condition.

Main Methods:

• Computed tomography angiography (CTA) is recommended as the initial diagnostic modality.
• Multi-disciplinary treatment approach is essential for etiology elucidation and therapeutic guidance.
• Open surgical intervention is the gold standard for intestinal necrosis; laparoscopy offers minimally invasive assessment.

Main Results:

• Emerging endovascular therapies show promise in the pre-necrotic phase.
• Continuous vigilance is essential to detect disease progression and adjust treatment.
• CTA demonstrates high sensitivity, specificity, and efficiency for diagnosis.

Conclusions:

• Prompt diagnosis and multi-disciplinary management, including surgical and endovascular options, are key to improving outcomes in AMI.
• Early recognition and intervention in acute mesenteric ischemia can significantly reduce mortality and morbidity.
