Summary
Physical examination effectively predicts negative angiograms in trauma patients. Pulse abnormalities or cold limbs strongly correlate with significant vascular injuries across various trauma types.
Area of Science:
- Trauma Surgery
- Vascular Surgery
- Diagnostic Imaging
Background:
- Traumatic injuries frequently involve vascular structures.
- Accurate assessment of vascular injury is critical for patient outcomes.
- Angiography is a key diagnostic tool in evaluating potential vascular damage.
Purpose of the Study:
- To evaluate the diagnostic utility of angiography in extremities with trauma.
- To correlate angiographic findings with clinical presentation and mechanism of injury.
- To determine the predictive value of physical examination findings for vascular injury.
Main Methods:
- Retrospective review of 119 extremity angiograms in patients with gunshot wounds, lacerations, and blunt trauma.
- Correlation of angiographic findings with clinical history and physical examination.
- Comparison of pre-procedure clinical assessment with post-procedure angiographic results.
Main Results:
- Angiograms performed solely due to proximity of injury showed no major arterial injuries.
- Significant vascular abnormalities were found in 44% of gunshot wounds, 80% of knife injuries, and 67% of blunt trauma when other indications were present.
- Pulse abnormalities or cold limbs were most frequently associated with positive angiographic findings (74% of cases).
Conclusions:
- Physical examination is a sensitive and effective tool for identifying patients unlikely to have vascular injuries.
- Clinical assessment can help guide the judicious use of angiography in trauma patients.
- Prompt identification of vascular abnormalities through clinical signs improves management decisions.
