AB1376 RELATIONSHIP BETWEEN INTRANEURAL HYPERVASCULARIZATION OF THE MEDIAN NERVE IN POWER DOPPLER AND ELECTROMYOGRAPHIC SEVERITY STAGES IN THE DIAGNOSIS OF SEVERITY OF CARPAL TUNNEL SYNDROME (PRELIMINARY RESULTS)

Background Carpal tunnel syndrome (CTS) is the most common in upper limbs. Ultrasound has been increasingly used recent years diagnosis of positive and severe CTS. Although severity essentially based on ENMG, several studies have shown that ultrasound data can also constitute criteria for Objectives The objective our study to evaluate relationship between intraneural hypervascularization median nerve power Doppler CTS measured by ENMG. Methods This a descriptive cross-sectional patients with clinically retained We excluded from operated who received cortisone infiltration previous six months. All underwent examination (B mode mode) electromyography one week apart. stages defined according classification Stevens (1997). still ongoing. Results To date we included 14 typical signs 25 wrists were examined sonographically mean age was 54± 10 years. Bilateral SCC present 11 patients. Of affected wrists: 10, 7 8 classified ENMG as mild, moderate respectively. On ultrasound, found 5 (20% studied): 10% mild-stage SCC, 14.3% moderate-stage 37.5% SCC. But this difference not statistically significant (p=0.31) probably related small size current sample (study ongoing). Conclusion preliminary results suggest could provide additional information carpal syndrome. be confirmed final results. References [1]Ghasemi-Esfe et All.
