Abstract

Purpose. To determine the sensitivity of colour-flow ultrasound in the detection of penetrating vascular injuries of the neck when compared with conventional  angiography.

Method. We prospectively imaged the neck arteries of all patients with suspected vascular injuries who were referred for angiography by the vascular surgeon over a 6-month period. All sonograms were performed by the same radiologist before angiography using a 7.5 or 10 MHz transducer on the same scanner. Data recorded were the presence or absence of vascular injury; the site of injury; and the type (intiinal, dissection, false aneurysm or fistula). Angiography was performed  immediately afterwards by a different radiologist. Results were correlated with the
angiogram and operative findings.

Results. 25 patients were studied. 15 patients had normal ultrasound studies and angiograms. Ultrasound studies were positive in 10 patients (40%), with false  aneurysms and arteriovenous fistulas detected in 8 patients; these were confirmed on angiography and at operation. There were intimal injuries in 2 patients (4%) that were undetected on angiography but confirmed at surgery. There were no  falsepositive or false-negative ultrasound studies.

Conclusion. Colour-flow ultrasound is sensitive in detecting vascular injuries and is suitable as a screening investigation in patients with penetrating neck injuries.
