ObjectiveTo explore the contrast-enhanced ultrasonography features of postpartum placenta implantation and its clinical value in diagnosis of postpartum placenta implantation.MethodsBetween April 2009 and May 2013, twelve patients with clinically suspected placenta implantation underwent contrast-enhanced ultrasonography in Hubei Maternal and Child Health Hospital. The location and extent of intrauterine lesions and perfusion features of contrast agent were observed. The contrast-enhanced ultrasonography features of postpartum placenta implantation were analyzed and compared with postoperative pathological diagnosis.ResultsIn twelve patients with placenta implantation, eleven showed enhancement. Only one lesion showed no enhancement, which was diagnosed as placental degeneration and calcification on postoperative pathology. One case was placenta adhesions conifrmed by postoperative pathological diagnosis, which presented with a hyperenhanced lesion in uterine cavity with a clear boundary to myometrium. Six cases were placenta implantation confirmed by postoperative pathological diagnosis, which presented with a residual placenta surrounded with extremely thin or evendiscontinuous uterine serosa. Five cases were placenta penetration confirmed by postoperative pathological diagnosis, which presented with a residual placenta penetrating the uterine serosa and contrast agent spilling out. All cases in this study were cured by operation.ConclusionsContrast-enhanced ultrasound could diagnose placenta implantation via the difference of tissue perfusion. The lesion of placenta implantation showed enhancement after injection of contrast agent. If discontinuous uterine serosa and contrast agent spilling was observed, placenta penetrating uterine serosa should be considered. Contrast-enhanced ultrasound has important clinical value in diagnosing postpartum placenta implantation and observing postoperative recovery processes of uterine rupture.
