Mesenteric Ischemia: Predicting Problems.

Area of Science:

• Vascular Surgery
• Gastroenterology
• Radiology

Background:

• Mesenteric ischemia is often diagnosed late, leading to non-salvageable bowel.
• Early identification of risk factors and warning signs is crucial for timely intervention.

Purpose of the Study:

• Identify risk factors for mesenteric ischemia.
• Recognize clinical warning signs and imaging findings for earlier diagnosis.
• Improve patient outcomes through prompt intervention.

Main Methods:

• Retrospective review of electronic health records (EHR) from November 2013 to December 2020.
• Included patients with atherosclerotic mesenteric ischemia, abstracting comorbidities and symptoms from the prior 6 months.
• Evaluated prior computed tomography (CT) scans for celiac artery and superior mesenteric artery (SMA) stenosis.

Main Results:

• Forty-five patients met inclusion criteria; common comorbidities included hypertension, hyperlipidemia, and heart disease.
• Over 50% reported suspicious abdominal symptoms within 6 months prior to admission.
• Significant SMA stenosis (>70%) on pre-presentation CT was associated with higher in-hospital mortality.

Conclusions:

• Patients at risk for mesenteric ischemia exhibit underlying vascular disease, prior concerning symptoms, and CT findings of mesenteric atherosclerotic disease.
• Prior imaging interpretation discordance highlights the need for careful review of CT scans.
• Proactive management based on identified risk factors and imaging may prevent acute mesenteric ischemia events.
