PAS

placenta accreta spectrum

OBJECTIVE To better understand placenta accreta spectrum (PAS) by correlating postoperative ultrasonographic findings of the explanted uteroplacental interface with intraoperative findings and gross pathology.

Obstetric complications, including placenta accreta spectrum (PAS), uterine rupture, placental malposition, abruption placenta, preterm delivery, threatened premature labor, premature rupture of membranes, and massive intrapartum hemorrhage, were assessed.

Paraffin sections were stained with haematoxylin and eosin (H&E) or periodic acid-Schiff (PAS) to assess inflammation.

Assessment of swallowing function was done before treatment (baseline), after treatment (2 weeks), and during follow-up (2 weeks after treatment) using the Fiberoptic Endoscopic Dysphagia Severity Scale (FEDSS) and the Penetration-Aspiration Scale (PAS).
