The importance of bladder volume in the ultrasound diagnosis of placenta accreta spectrum disorders.

ABSTRACT:

Objective

To assess how a quantifiable measure of vascularity-i.e. abnormal confluence (A_con ) in the subplacental myometrium observed by three-dimensional power-Doppler ultrasonography-changes with different bladder volumes.

Methods

In a prospective observational study, women referred to a tertiary UK center with suspected PAS disorders were recruited between August 2016 and May 2017. The largest area of confluent three-dimensional power-Doppler signal (A_con ) at the uteroplacental interface was estimated under two bladder volumes differing by at least 200 mL.

Results

A_con was calculated for 14 women, of whom seven were subsequently found to have PAS disorders. For these seven women, log(A_con ) was significantly greater whe
