Intrauterine Inflated Foley's Catheter Balloon in the Management of Abnormally Invasive Placenta Previa: A Case-Control Study.

Objective: To describe the use of intrauterine inflated Foley's catheter balloon for control of postpartum hemorrhage (PPH) during cesarean section (CS) in cases of abnormally invasive placenta previa aiming to preserve the uterus.

Methods: Retrospective case-control study of the data of women who underwent elective CS on abnormally adherent placenta previa was carried out. Women in whom inflated Foley's catheter balloon was used for control of PPH during CS ( = 40) were compared with a control group of women who underwent elective CS by the same technique but without use of intrauterine catheter balloon ( = 38).

Results: Use of intrauterine inflated Foley's catheter balloon significantly reduced the estimated amount of blood loss ( = 0.008), amounts of crystalloids, colloids and packed red blood cells transfusion ( = 0.025, 0.017 and 0.022, respectively), and the need for bilateral internal iliac artery (IIA) ligation ( = 0.016). No significant difference was observed between both groups regarding the use of massive transfusion protocol, performing cesarean hysterectomy, relaparotomy, and admission to the intensive care unit.

Conclusion: Application of an intrauterine inflated Foley's catheter balloon during CS in cases of morbidly adherent placenta previa helps to control PPH with preservation of the uterus and decreases the need for the invasive IIA ligation.
