Mesenteric Vascular Injury in Trauma: An NTDB Study.

Area of Science:

• Trauma Surgery
• Vascular Surgery
• Emergency Medicine

Background:

• Abdominal trauma is a significant cause of death and disability.
• Mesenteric vascular injuries (MVIs) are serious but lack large-scale outcome studies.
• This study investigates factors influencing outcomes in patients with MVIs.

Purpose of the Study:

• To analyze outcomes in patients with trauma-induced mesenteric vascular injuries.
• To identify patient demographics and injury characteristics associated with mortality and hospital stay.
• To compare outcomes between blunt and penetrating mechanisms of MVI.

Main Methods:

• Retrospective analysis of the 2012 National Trauma Data Bank.
• Inclusion of patients diagnosed with mesenteric vascular injury (ICD-9 902.20-902.29).
• Analysis of mortality, hospital length of stay, and disposition based on age, gender, race, Injury Severity Score (ISS), and injury type (blunt vs. penetrating).

Main Results:

• Penetrating injuries (32%) had higher mortality (21%) than blunt injuries (65%, 16%).
• Higher ISS significantly increased mortality risk (ISS >16: 5.39x, ISS >25: 15.1x).
• Older age (>65) and specific arterial injuries (hepatic, superior mesenteric) were associated with increased mortality.

Conclusions:

• Mesenteric arterial injuries require prompt diagnosis and treatment due to high morbidity and mortality.
• Penetrating mechanisms, severe injury severity scores, and damage to major mesenteric vessels are key predictors of poor outcomes.
• Early management strategies are essential to improve survival rates for MVI patients.
