Conclusions
We present here 4 cases in which ultrasound guided the surgical management of patients in our practice. Additional research in the use of HRU in the evaluation of peripheral nerve injuries is warranted. Specifically, more data on the efficacy of HRU in aiding in the diagnosis of injuries to the spinal accessory nerve and peripheral nerve injuries caused by iatrogenic and traumatic pseudoaneurysms are needed. High-resolution ultrasound has been shown to be a useful tool in the diagnosis of peripheral nerve injuries when used in combination with physical examination and EMG. Ultrasound also provides dynamic imaging, is cost-efficient, and is more widely available than MRI.
