Abstract

The worldwide incidence of abnormally invasive placenta is rapidly rising following the trend of increasing caesarean delivery. It is a heterogeneous condition and has a high maternal morbidity and mortality rate, presenting specific intra-partum challenges. Its rarity makes developing individual expertise difficult for the majority of clinicians. The International Society for Abnormally Invasive Placenta aims to improve clinicians understanding and skills in managing this difficult condition. By pooling knowledge, experience and expertise gained within a variety of different healthcare systems the society seeks to improve the outcomes for women with abnormally invasive placenta globally. The recommendations presented herewith were reached using a modified Delphi technique and are based on the best available evidence. The evidence base for each is presented using a formal grading system. The topics chosen address the most pertinent questions regarding intra-partum management of abnormally invasive placenta with respect to clinically relevant outcomes including: Definition of a center of excellence; requirement for antenatal hospitalization; antenatal optimization of hemoglobin; gestational age for delivery; antenatal corticosteroid administration; use of pre-operative cystoscopy, ureteric stents and prophylactic pelvic arterial balloon catheters; maternal position for surgery; type of skin incision; position of the uterine incision; use of inter-operative ultrasound; prophylactic administration of oxytocin; optimal method for intra-operative diagnosis; use of expectant management; adjuvant therapies for expectant management; use of local surgical resection; type of hysterectomy; use of delayed hysterectomy; intra-operative measures to treat life-threatening hemorrhage; fertility after conservative management.
