Neutrophil-to-lymphocyte ratio and mesenteric ischemia: can it predict the etiology of mesenteric ischemic at computed tomography?
To assess the usefulness of the neutrophil-to-lymphocyte ratio (NLR) as a predictive factor of acute mesenteric ischemia (AMI) in patients presenting at the emergency department (ED) with acute abdominal pain. ⋯ The NLR is a useful parameter of AMI of arterial origin due to occlusion of the SMA; it can help the clinician to raise suspicion of this diagnosis and the interpreting radiologist in the acquisition protocol for the CT study and would alert for an early surgical treatment.

Utility of biphasic multi-detector computed tomography in suspected acute mesenteric ischemia in the emergency department.
To retrospectively evaluate the utility of biphasic multi-detector computed tomography (MDCT) with arterial and portal venous phases for the detection of suspected acute mesenteric ischemia (AMI) in emergency department (ED) patients compared to limited surgical confirmation. ⋯ Emergent biphasic MDCT demonstrated low but non-trivial yield (11.1%) for the depiction of suspected acute mesenteric ischemia but was particularly low for occlusive venous AMI (0.9%). The relationship between serum lactate elevation and positive MDCT findings of AMI in our study conforms to prior work and cautiously suggests value in routine serum lactate assessment preceding imaging for patient prioritization.
