Value of transvaginal and abdominal color Dopplerultrasonography in diagnosis of ovarian cyst pedicle torsion in 43 cases

  Objective  To study the clinical value of transvaginal and abdominal color Doppler ultrasound in the diagnosis of ovarian cyst pedicle torsion.

  Methods  A total of 43 patients with ovarian cyst torsion who underwent surgery in our hospital were enrolled. All these patients underwent abdominal ultrasound and vaginal ultrasonography, and were diagnosed by pathology and surgery, taking pathological diagnosis as golden standard. The sonographic performance, diagnostic results and clinical application value of the two ultrasound examinations were observed and analyzed.

  Results  The accuracy of vaginal ultrasonography in 43 cases was significantly higher than that of abdominal ultrasonography (93.02% vs. 67.44%, P < 0.05). A few patients were misdiagnosed as hydrosalpinx torsion, rupture of ectopic pregnancy and rupture of corpus luteum cyst. The misdiagnosis rate and missed diagnosis rate of transvaginal ultrasound were 4.65% and 2.33% respectively, which were significantly lower than 18.60% and 13.95% respectively in transabdominal ultrasound (P < 0.05).

  Conclusion  Transvaginal ultrasonography has good clinical value in diagnosis of ovarian cyst pedicle torsion, which can effectively detect the lesion and has higher convenience and accuracy. At the same time, it is suitable for diagnosis of small or moderate pedicle torsion lesions because of its obvious echo characteristics.
