More Options Empower Mothers
Overall, the results support the use of delayed hysterectomy and conservative management as safe alternatives to cesarean hysterectomy, especially in those with severe PAS (opting for IH Instead of CH) and those seeking to preserve the uterus (CM), Dr. Amro said. However, these alternative options can be offered only to patients who can engage in frequent postpartum follow-up and live close to the hospital; with the CM group, resorption/passage of the placenta may take as long as 6 months in some cases, she explained.
The greatest concerns with leaving the placenta in place in PAS patients are the risk of infection or subsequent hemorrhage, Dr. Amro said in an interview. However, the current study showed that the infection rate was not as high as anticipated, and the frequency of unplanned procedures occurred in only 20%, which should alleviate some of these concerns, she said.
“We have completed 28 cases of conservative management since 2015, four have gone on to successful pregnancy with no cases of PAS in the subsequent pregnancies,” Dr. Amro said. Conservative management gives mothers another option, she added. “Moms feel empowered by being given a choice, especially for those that want to keep their uterus for fertility or religious/cultural considerations, and many opt for CM.”
The next step is to take the conservative management strategy to larger groups at other centers to replicate the results in other locations, said Dr. Amro. “Also, we are looking at the utility of other interventions such as uterine artery embolization and performing delayed dilation and curettage to help with passage of the placenta in those opting for CM.”
Study Supports Safety of Conservative Management
“There are patients that may want to preserve their reproductive organs in the face of an accreta (such as for religious, cultural, and personal reasons), and this study helps address some of the safety considerations with conservative approaches,” Corrina M. Oxford-Horrey, MD, a maternal-fetal medicine specialist at Weill Cornell Medicine, New York, said in an interview.
“I was surprised that there was not a lot of infectious morbidity (such as sepsis) in the cohorts; that was helpful to see,” said Dr. Oxford-Horrey, who served as a moderator for the session in which the study was presented.
Based on the study findings, “nontraditional approaches to placenta accreta spectrum management may be reasonable, given similar overall postoperative composite morbidity between the groups,” she said.
As for additional research, replicating the study in a multicenter fashion would add to the generalizability of the findings, Dr. Oxford-Horrey said.
The study received no outside funding. The researchers and Dr. Oxford-Horrey had no financial conflicts to disclose.
