The purpose of this study was to describe the color Doppler sonographic findings in adnexal torsion that distinguish viable from nonviable ovaries. We present the color Doppler sonographic features in 13 patients with surgically proved adnexal torsion that help determine whether or not the ovaries were viable or nonviable at the time of surgery. Eleven combined ovarian and tubal torsions and two isolated tubal torsions were studied. In 10 cases the ovaries were considered nonviable at the time of surgery and in three cases they were considered viable. Of the nonviable group, six showed absent arterial and venous flow centrally, but two had low velocity (< 5 cm/s) arterial flow peripherally in the region of the adnexal branch of the uterine artery or in the main ovarian artery, and two demonstrated absent or reversed diastolic arterial flow. None of the nonviable ovaries showed venous flow centrally. In contrast, all of the viable ovaries demonstrated venous flow centrally, and two had peripheral and central arterial flow. Although the CDS findings in adnexal torsion are variable, ovarian viability may be predicted if central venous flow is present.
