The validity of normal arteriography in penetrating trauma
Insights
Arteriography accurately detects arterial injuries in penetrating trauma, especially when clinical signs are unclear. This imaging technique helps rule out significant vascular damage, guiding surgical decisions effectively.
Area of Science:
- Vascular Surgery
- Trauma Management
- Diagnostic Imaging
Background:
- Penetrating trauma poses challenges in detecting arterial injuries.
- Unrepaired injuries can lead to arteriovenous fistulas and false aneurysms.
- The diagnostic accuracy of arteriography for occult injuries requires definition.
Purpose of the Study:
- To evaluate the diagnostic accuracy of arteriography in patients with penetrating extremity trauma.
- To determine the sensitivity and specificity of arteriography in identifying arterial injuries.
- To correlate arteriographic findings with operative exploration results.
Main Methods:
- 177 patients with 183 penetrating extremity wounds were included.
- All patients underwent arteriography followed by surgical exploration.
- Arteriogram and operative findings were compared for correlation.
Main Results:
- Arteriography demonstrated 36 true-positive, 132 true-negative, 14 false-positive, and 1 false-negative results.
- The study found arteriography sufficiently sensitive to exclude arterial injury in cases with equivocal clinical signs.
- Radiographic subtleties necessitate careful technique and interpretation for accuracy.
Conclusions:
- Arteriography is a reliable tool for excluding arterial injury in penetrating trauma with unclear clinical presentation.
- Attention to technical details and interpretation is crucial for maximizing diagnostic accuracy.
- Clear clinical signs of arterial injury or any arteriographic abnormality warrant surgical exploration.
Abstract:
The detection of underlying arterial injury is a major problem in the management of penetrating trauma. Arteriovenous fistula and false aneurysm are late sequelae of unrepaired injuries. The diagnostic accuracy of arteriography in clinically occult injury has not been defined. One hundred and seventy-seven patients with 183 penetrating extremity wounds underwent arteriography followed by operative vessel exploration. Arteriogram/operation correlation demonstrated 36 true-positive, 132 true-negative, 14 false-positive, and one false-negative arteriogram. Arteriography is sufficiency sensitive to exclude the presence of arterial injury in patients with equivocal clinical signs of injury. The radiographic changes are often sublte and diagnostic accuracy demands attention to the details of technique and interpretation. Unequivocal clinical signs of arterial injury and any arteriographic abnormality are indications for operative exploration.
