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.
本研究的目的是描述附件扭转时彩色多普勒超声检查结果，以区分存活与非存活的卵巢。我们呈现了13例经手术证实为附件扭转患者的彩色多普勒超声特征，这些特征有助于确定手术时卵巢是否存活。研究了11例卵巢和输卵管联合扭转以及2例单纯输卵管扭转。10例患者的卵巢在手术时被认为已无活力，3例被认为仍有活力。在无活力组中，6例中央动脉和静脉血流均消失，但2例在子宫动脉附件分支区域或主卵巢动脉区域周边有低速（<5 cm/s）动脉血流，2例舒张期动脉血流消失或反向。所有无活力的卵巢中央均未显示静脉血流。相比之下，所有有活力的卵巢中央均显示有静脉血流，2例同时有周边和中央动脉血流。尽管附件扭转时彩色多普勒超声表现各异，但如果存在中央静脉血流，则可预测卵巢的存活情况。
