A new approach to fertility-preserving surgery in patients with placenta accreta.

BACKGROUND

The aim of this study was to evaluate the efficacy of a novel combined surgical approach utilising: (1) two autonomous balloon Zhukovsky catheters (vaginal and uterine), (2) bilateral ligation of the descending uterine artery branches, (3) external supraplacental pleated sutures, and (4) either excision of a small area of placenta accreta or full metroplasty, for the management of uterine bleeding associated with placenta accreta of various severity.

MATERIALS AND

METHODS

The study included medical records of 92 pregnant women with placenta accreta undergoing a caesarean section. To evaluate the efficacy of the proposed management strategy, study participants were divided into three groups. In Group 1 (controls, n = 47), we utilised the combination of bilateral ligation, Barinov external supraplacental pleated sutures, and either excision of the tightly attached portion of placenta accreta or metroplasty. In Group 2 (n = 20), the abovementioned surgical techniques were additionally combined with balloon tamponade using an intrauterine Zhukovsky catheter. In Group 3 (n = 25), we additionally used an intravaginal Zhukovsky balloon catheter to enhance the efficacy of intrauterine tamponade.

RESULTS

The use of an intrauterine balloon catheter combined with metroplasty was associated with a reduction in blood loss volume and blood transfusion rate by 1.9-fold, while the use of intravaginal balloon catheter reduced blood transfusion rate by 2.4-fold. The uterine balloon catheter reduced the risk of hysterectomy by 11-fold.

CONCLUSION

Simultaneous use of two Zhukovsky balloon catheters (intravaginal and intrauterine) during caesarean section facilitates fertility-preserving surgery in patients with placenta accreta even in the cases of low-segment bleeding, thereby representing a promising approach to management of these patients.
