High Frequency Ultrasound And Electrical Evoked Potential Joint Application Value To Investigate The Diagnosis Of Brachial Plexus Neuropathy

In recent years due to the number of patients with traumatic brachial plexus injury showed a gradual upward trend in recent years of brachial plexus injury is very common in patients on bed, the disease is more difficult, in the process of treatment and poor prognosis, but also have high morbidity for best results of treatment to the family and society, and the medical profession has brought certain impact and pressure on the current medical technology, there is no way to completely cure, many experts believe that also is a more serious disease treatment measures to face the difficulties, for brachial plexus injury is safe or incomplete injury brachial plexus, authority figures, many of the medical school, most of the time is the use of nerve transposition or neural lax to treat transplant method. Choose the right treatment, the maximum recovery of limb function, which puts forward higher requirements on the accurate positioning and qualitative diagnosis of the injured nerve. Before the surgery should be performed high frequency ultrasound on the damaged parts, the continuity of nerve structure. However, in the process of judgment for the two all have a certain influence, the accuracy is not very obvious, there are some limitations. The clinical application of combined diagnosis can significantly improve the sensitivity and accuracy of detection of brachial plexus lesions, reduce misdiagnosis and missed diagnosis, has more significant advantages than single detection method for diagnosis, can provide more accurate and reliable basis for clinical treatment scheme is confirmed.For brachial plexus injury or disease nerve incomplete injury before operation, most of the time is the A Yong ultrasound examination, mainly in the inspection process is damaged nerves and linear hyperechoic continuous interruption or appear after interruption all properties, interruption phenomena exhibit it is sound or silent phenomenon. Fuzzy linear echo, observation of ultrasonic detection results and the actual is obvious, from these results we can see that, the sensitivity, specificity and accuracy were 77%, 75%, 77%. High frequency ultrasound can play a role and a good help, you can distinguish the brachial plexus and surrounding tissue, injury of brachial plexus to the diagnosis, treatment and postoperative reference.
