Signs and symptoms of mesenteric artery occlusion, and how you test for it
Metadata[+] Show full item record
Acute mesenteric occlusion (AMO) is characterized by severe abdominal pain “out of proportion” to physical examination, whereas chronic mesenteric occlusion (CMO) is characterized by postprandial abdominal pain that progresses over weeks to months (SOR: C, based on consensus and case-series data). No reliable serum markers exist for the detection of MO (SOR: B, based on observational studies with conflicting results). Contrast-enhanced multidetector computed tomography (MDCT) most reliably detects AMO (SOR: A, based on a systematic review). Sonography (US), CT, and magnetic resonance angiography (MRA) help diagnose CMO (SOR: C, based on consensus and case-series data).
