GARCIA SARAVI, P. et al. La ecografía Doppler en la detección de invasión vesical en la placenta percreta: nuestra experiencia. Rev. argent. radiol. [online]. 2014, vol.78, n.3, pp.149-155. ISSN 1852-9992.  http://dx.doi.org/10.1016/j.rard.2014.05.002.

Purpose: To demonstrate the usefulness of Doppler ultrasound in the detection of bladder invasion in cases of placenta percreta. Materials and methods: Twenty-one patients, aged 20-44 years old, with surgery and histopathological diagnosis of placenta accreta were tested with ultrasound between November 2011 and May 2013. We considered bladder invasion the presence of hypervascularity detected with Doppler ultrasound, and probable invasion the presence of signs in gray-scale ultrasound, without Doppler color. Results: From the 21 patients included in the study with placenta accreta, 7 had bladder invasion in the histopathological study. Out of these seven, five had been reported to have bladder invasion because of the presence of hypervascularity detected with Doppler ultrasound, and the 2 remaining were reported as probably affected. Regarding the other 14, 7 were reported as normal in the ultrasound, and 7 as probable. Conclusion: Doppler ultrasound is a very reliable method to detect bladder invasion in placenta percreta, seen as hipervascularity of the uterine-bladder interface in the Doppler color exam.
