Abstract:

Introduction.—Diagnosis and repair of arterial injury from penetrating trauma is critical because the lack of intervention can result in limb loss or death. Patients that have conspicuous arterial injuries can be explored and repaired in the operating room with or without preoperative diagnostic imaging. Patients without definite clinical evidence of vascular injury (i.e., hematoma, pulsatile mass, bruit, or pulse deficit) generally undergo angiography because of proximity of injury. Arteriography is an expensive and invasive procedure for patients; it carries some discomfort and has potential complications associated with its use. In our experience, ankle/brachial index (ABI) alone has not been a dependable study to rule out significant arterial injury of extremities. Color flow duplex imaging is a painless procedure, has no risk to the patient, is not as expensive as arteriography and is readily available in most institutions. We present two patients who had normal pulses and ABIs after gunshot wounds to extremities. Both patients had significant arterial injury detected by color flow duplex imaging as the initial diagnostic modality and subsequently proceeded on to arteriography based on the findings of the duplex studies.

Conclusions.—The findings of the duplex imaging were in direct correlation with arteriography. These two cases demonstrate the sensitivity of color flow duplex ultrasonography to detect extremity arterial injuries in a community hospital.
