Placenta Accreta Management

The goal of this observational study is to evaluate the feasibility and safety of utilizing adjunctive mechanical towel compression during TLS-CCA, measured primarily by estimated intraoperative blood loss in patient with Maternal age 18-45 years - Singleton pregnancy - Antenatal diagnosis of PAS (ultrasound ± MRI) - Planned elective cesarean delivery - Candidate for uterine preservation via TLS-CCA - Provided written informed consent

Placenta accreta spectrum (PAS) disorders, characterized by abnormal trophoblastic invasion into the myometrium, have seen a global rise in incidence primarily driven by increasing cesarean delivery rates. Massive obstetric hemorrhage remains the leading cause of maternal morbidity and mortality in these cases. While cesarean hysterectomy is the traditional gold standard for severe PAS, uteruspreserving procedures are increasingly preferred by patients desiring future fertility. Total lower uterine segmentectomy with cervico-corporeal anastomosis (TLS-CCA) is a recognized conservative technique that involves excising the invaded lower segment and reconstructing the uterus. Despite removing the primary placental implantation site, diffuse bleeding from the highly vascularized remaining myometrial bed, dissected bladder flap, and pelvic collateral vessels often persists. While traditional compression sutures or specialized devices are utilized for hemostasis, they can be costly or technically challenging in distorted anatomies. This study introduces a novel, simple, and cost-effective approach: the use of tightly rolled sterile surgical towelsapplied as direct mechanical compression against the lower uterine segment and bladder bed during dissection and reconstruction.
