How to perform the one-step conservative surgery for placenta accreta spectrum move by move.

BACKGROUND: There are 3 treatment options for placenta accreta spectrum: cesarean delivery with hysterectomy, expectant management, and uterine-sparing surgical techniques. One-step conservative surgery is the most extensively described conservative surgical technique, and it has extensive evidence supporting its usefulness; however, few groups apply it, most likely because of the misconception that it is a complex procedure that requires extensive training and is applicable to only a few patients. OBJECTIVE: This study aimed to evaluate the clinical outcomes of patients undergoing one-step conservative surgery in 4 placenta accreta spectrum reference hospitals and provided detailed steps for successfully applying this type of surgery. STUDY DESIGN: This was a multicenter, descriptive, prospective study that described the outcomes of patients with placenta accreta spectrum treated in 4 reference hospitals for this condition. The patients were divided into those managed with one-step conservative surgery and those managed with cesarean delivery and hysterectomy. RESULTS: Overall, 75 patients were included. One-step conservative surgery was possible in 85.3% of placenta accreta spectrum cases (64 patients). Intraoperative staging and placenta accreta spectrum topographic classification allowed for the selection of one-step conservative surgery candidates. The clinical outcomes of the 2 groups were similar, except for the frequency of transfusions (81.8% in the cesarean delivery and hysterectomy group vs 67.2% in the one-step conservative surgery group) and vascular interventions (27.3% in the cesarean delivery and hysterectomy group vs 4.7% in the one-step conservative surgery group), which were both higher in patients who underwent hysterectomy. In addition, the operation time was shorter in the one-step conservative surgery group (164.4 minutes vs 216.5 minutes). CONCLUSION: One-step conservative surgery is a valid procedure in most patients with placenta accreta spectrum. It is an applicable technique even in scenarios with limited resources. However, its safe application requires knowledge of the topographic classification and the application of intraoperative staging.

Placenta accreta spectrum: intraoperatory analysis for immediate tele-help.

INTRODUCTION: Placenta accreta spectrum (PAS) is a potentially fatal disease. A quarter of PAS cases are not detected during prenatal evaluations, so obstetricians without experience with this disease may encounter complex cases without having the necessary resources. We report a series of PAS intraoperative finding (IOF) cases and analyze useful strategies to improve patient outcomes. CASE SERIES: Four cases of PAS IOF are reported. These patients were women with previous pregnancies terminated by cesarean section, with placenta previa/anterior, and whose prenatal ultrasound did not detect PAS. Three patients were candidates for the postponement of cesarean section and/or hysterectomy. One case had active vaginal bleeding, so it was not feasible to delay surgery. Patients who benefited from delaying surgery or seeking additional help through telesupport had better clinical outcomes. CONCLUSION: Decisions about which interventions to conduct and which to delay in cases of PAS intraoperative finding can determine the clinical outcome.
