ObjectiveTo evaluate the value of high-frequency color Doppler ultrasonography in the diagnosis of femoral hernia. MethodsThe ultrasonographic features of 39 femoral hernias in 37 patients treated between March 2008 and October 2013 were retrospectively analyzed, and the results were confirmed by surgery. ResultsThirty-nine femoral hernias were diagnosed by surgery, including 19 in the right side, 16 in the left side, and 2 with double-side hernias. Thirty-seven femoral hernias were diagnosed with ultrasonography. Two femoral hernias were misdiagnosed as lipoma in one, and as enlarged lymph nodes in one, respectively. Ultrasound diagnosis accurate rate was 94.9% (37/39). Hernia content could be seen through surgery in 28 cases, and the ultrasound accurate rate in assessing the hernia content was 85.7% (24/28). ConclusionUltrasonography is the first choice for improving the diagnosis efficacy of femoral hernia.
