Indications for angiography in extremity trauma
Insights
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.
Abstract:
The angiograms of 119 extremities of patients with gunshot wounds (65), lacerating injuries (17), and blunt trauma (29) were retrospectively evaluated and correlated with clinical history. Indications for angiography were decreased or absent pulse or blood pressure, cold limb, bruit or murmur, uncontrolled bleeding or increasing hematoma, neurologic deficit, and proximity of the injury to vascular structures. Angiographic findings were compared with preprocedure clinical assessment. Angiograms performed only because of proximity of the wound/injury to major vessels showed no major arterial injuries. However, angiograms performed for one or more of the other indications demonstrated significant vascular abnormalities in 44% of gunshot wounds, 80% of knife injuries, and 67% of blunt trauma. Of the indications for arteriography, pulse abnormalities or cold limbs were most often associated with significant angiographic findings, positive studies occurring in 74% of cases. Despite the differences in mechanism of injury, physical examination is sensitive and effective in predicting which patients will have negative angiographic studies after each of the three forms of trauma.
