Abstract

Objective: Ultrasonography (US) is an acceptable tool to diagnose the placenta accreta spectrum (PAS) among pregnant women. However, the lack of a robust criteria for diagnosis and predicting the severity of the consequences facing pregnant women requires identification of novel biomarkers. Material and Methods: This prospective, cross-sectional study was performed on pregnant women with a probable diagnosis of PAS. Their demographic information, medical and surgical history, blood loss severity (severe ≥2500 mL) following hysterectomy, and the histopathology after the surgery were collected. In addition, the Doppler imaging of both uterine arteries, including the pulsatility index, resistance index, peak systolic velocity (PSV), the PSV of the posterior part of the bladder, cervix, the largest lacuna, and the posterior lacuna of the bladder were calculated by Doppler US. Data were analyzed to investigate the relationship between Doppler markers and the severity of PAS in terms of bleeding, hysterectomy, and histopathology. Results: Fifty-one women were enrolled with a mean age of 35.4±4.11 years and 17 (33.3%) had severe bleeding. There were significant differences between median (range) bladder PSV [57 (34-90) vs. 33 (20-64); p<0.001], cervix PSV [26 (0-63) vs. 18 (0-76); p=0.04] and left uterine artery [89 (81-135) vs. 68 (61-113); p=0.045] for women with and without severe bleeding, respectively. Thirty-four (66.66%) had hysterectomy. Comparison of bladder PSV, cervix PSV, and left uterine PSV for women with and without hysterectomy were 46 (20-90) vs. 39.5 (33-46) (p=0.005), 20 (0-76) vs. 20 (14-26) (p=0.013) and 68 (61-135) vs. 82 (63-101) (p=0.003), respectively. Conclusion: Bladder PSV, cervix PSV, and uterine PSV were significantly higher in pregnant women with PAS, and they may be useful diagnostic and prognostic markers. © 2023 by the Turkish-German Gynecological Education and Research Foundation.
