Abstract
Objective: Management of patients with placenta accreta spectrum (PAS) by trained multidisciplinary teams is associated with improved outcomes. Ultrasound can predict intraoperative risks, but expert ultrasound imaging of PAS is often limited. Telemedicine is used increasingly in obstetrics, permitting expert consultation when essential resources are not available locally. Our objective was to evaluate the feasibility of teleconsultation using standardized ultrasound image acquisition and reporting, and to correlate prognosis with intraoperative findings in patients at risk for PAS. Methods: A total of 12 PAS imaging experts (teleconsultants) were selected to asynchronously review deidentified standardized grayscale and color Doppler ultrasound images for five patients who had completed treatment for PAS, resulting in 60 individual teleconsultations. All patients were managed at a center using standardized imaging acquisition and intraoperative topographic classification to individualize surgical management. Teleconsultants reported the predicted topographic classification and recommended a surgical approach based on the topographic classification algorithm. Prognoses were compared with that reported by the local sonologist and with intraoperative findings. Results: In all five patients, local sonologist prognosis and antenatal topographic classification was confirmed during surgery and the final surgical approach matched that which was recommended preoperatively. Teleconsultant antenatal evaluation and management plans matched those of the local team in 71.7% of the cases. When reports differed, PAS severity was overestimated in nine reviews (16.9%) and was underestimated in six reviews (11.3%). Conclusion: Remote imaging teleconsultation provides accurate prenatal staging in most patients at risk for PAS. Teleconsultation is a feasible strategy to improve prenatal imaging, management planning, and guidance for local teams in settings with limited healthcare resources.
