Key Points about Acute Mesenteric Ischaemia:

  • Definition: Acute Mesenteric Ischaemia is a life-threatening condition characterized by the sudden reduction of blood flow to the small intestine, leading to ischemia and necrosis.
  • Causes: The primary causes include embolism, thrombosis, non-occlusive mesenteric ischemia (NOMI), and mesenteric venous thrombosis.
  • Symptoms: Symptoms typically include sudden, severe abdominal pain, nausea, vomiting, and in later stages, signs of peritonitis. The pain is often disproportionate to the physical findings.
  • Diagnosis: Diagnosis involves clinical suspicion based on symptoms, with confirmation via imaging studies such as CT angiography, which is the gold standard. Laboratory tests may show elevated lactate levels, indicating tissue ischemia.
  • Management: Management includes immediate resuscitation, anticoagulation, and surgical intervention to restore blood flow. In cases of non-occlusive mesenteric ischemia, vasodilators may be used. Early intervention is crucial to prevent bowel necrosis and death.
  • Complications: If not promptly managed, complications include bowel necrosis, sepsis, multi-organ failure, and death.
