Summary
Delayed angioembolization (AE) in blunt trauma patients increases 24-hour mortality. Ensuring timely AE is crucial for improving outcomes in patients with intra-abdominal solid organ injuries.
Area of Science:
- Trauma Surgery
- Interventional Radiology
- Emergency Medicine
Background:
- Angioembolization (AE) is vital for hemostasis in trauma patients.
- Guidelines recommend interventional radiologists be available within 30 minutes for emergent AE.
- The impact of AE timing on patient outcomes remains unclear.
Purpose of the Study:
- To investigate the association between the timing of angioembolization (AE) and patient outcomes.
- To determine if delayed AE increases mortality and blood transfusion requirements in blunt intra-abdominal solid organ injuries.
Main Methods:
- Retrospective review of the ACS Trauma Quality Improvement Program database (2013-2016).
- Included adult patients with blunt intra-abdominal solid organ injury undergoing AE within 4 hours of admission.
- Analyzed 24-hour mortality and blood product transfusions, grouped by AE timing intervals.
Main Results:
- Analyzed 924 eligible patients; mean age 44 years, 66% male.
- Every hour delay in AE was significantly associated with increased 24-hour mortality (p < 0.05).
- Earlier AE correlated with decreased 24-hour mortality on univariate analysis (p = 0.016).
Conclusions:
- Delayed angioembolization for hemorrhagic control in blunt trauma is linked to higher 24-hour mortality.
- Trauma centers must prioritize timely AE by ensuring interventional radiologist availability.
- Optimizing AE timing should be a focus for quality improvement initiatives in trauma care.
