Abstract
Purpose
The aim of this study is to report on a single center experience of managing patients affected by placenta previa major and/or accretism by embolizing uterine arteries immediately before the cesarean delivery to reduce blood loss and secondary the rate of hysterectomies.
Materials and methods
Sixty-nine patients have been prospectively enrolled. Inclusion criteria were radiological diagnosis of placenta anomalies and risk factors for peri/postpartum hemorrhage. The delivery was electively scheduled between the 35th week and the 36th week of pregnancy. The embolization procedure was performed in the gynecological operating room with a mobile C-arm by injecting calibrated microparticles 500–700 μm. A contrast-enhanced MRI was acquired in a subgroup of 10 patients 6 months after the delivery to evaluate the uterine wall status.
Results
Hysterectomy had been performed in 43.5%; 52.2% did not require blood transfusions; 1.2 blood units per patient had been meanly transfused. The mean fluoroscopy beam-on time was 195 s per patient. The mean uterine dose was 26.75 mGy. No pH anomalies were measured from the umbilical cord blood; the Apgar score at 5 min was ≥8. The analysis of the neuro-developmental milestones showed normal cognitive development in all children at 6 months. The uterine wall enhancement evaluated with contrast-enhanced MRI 6 months after the embolization procedure showed preserved myometrial perfusion without area of necrosis.
Conclusions
In this series of patients, the predelivery uterine arteries’ embolization was a safe and effective procedure; this may represent a technical alternative that interventional radiologists can consider when facing this challenging scenario.
