The anesthetic approach to a patient with placenta accreta spectrum

Alexander Ioscovich et al. Curr Opin Anaesthesiol. .

Abstract

Purpose of review: Placenta accreta poses significant risk of morbidity and mortality to a laboring patient. Here we review available treatment options, highlight trends in bleeding prevention and diagnosis that have been shown to improve patient outcome, and provide best practice suggestions. We also discuss the decision-making process for choice of anesthesia, as it is not based on a gold-standard paradigm.

Recent findings: The use of resuscitative endovascular balloon occlusion of the aorta has been gaining popularity around the world. It has been shown to cause an equivocal reduction in perioperative bleeding in placenta accreta spectrum (PAS), reduce the rate of hysterectomies, and is a safe and relatively easy technique. There are other invasive radiology techniques that have also proven to be beneficial in bleeding prevention: balloon occlusion of hypogastric arteries intraoperatively, internal iliac artery embolization, and intraoperative ligation of the hypogastric or uterine arteries.

Summary: Optimal management of PAS begins with early and definitive diagnosis. A multidisciplinary approach along with preparation of special equipment and the use of a check-list maximize the chance for success. Anesthesia could be done with all types of regional or under general, considering case-by-case factors but most importantly choosing according to the institution's best facility and skill.
