OBJECTIVE: To evaluate the role of Doppler flow in the diagnostic process of ovarian torsion.METHODS: Twenty-two patients who displayed the clinical symptoms of abdominal pain concomitant with an ovarian mass and were scheduled for explorative laparoscopy were enrolled in the study. The cohort was divided into 3 groups: (A) 8 patients with clinical and sonographic evidence of torsion; (B) 8 patients with abdominal pain and sonographic diagnosis of hemorrhagic cyst; and (C) 6 patients with a simple cystic mass who had undergone explorative surgery due to abdominal pain.RESULTS: After Doppler flow imaging, Group A displayed no blood flow within the mass, and surgery confirmed the diagnosis of ovarian torsion. Seven of the 8 group B patients showed ovarian vascular flow (RI = 0.472 +/- 0.067). Only 2 of the 6 Group C patients displayed vascular flow (RI = 0.680 +/- 0.129) within an untwisted cyst, confirmed by laparoscopy.CONCLUSIONS: The combination of Doppler flow imaging with the morphologic assessment improves the diagnostic accuracy of ovarian torsion.
