Disorders of the Placenta Accreta Spectrum (PAS) pose serious dangers
to the health of mothers and can be lethal, making them a major concern in
contemporary obstetrics. Placenta accreta, increta, and excreta are among
the anomalies that fall under the umbrella of PAS. These abnormalities involve
aberrant placental adhesion to the uterine wall. As the number of caesarean
births and other uterus procedures has increased, so too have these disorders.
Obstetricians, maternal-fetal medicine specialists, anesthesiologists,
radiologists, and occasionally urologists and vascular surgeons must all work
together to manage PAS effectively. The purpose of this essay is to go over the
current approaches of managing women with PAS and their results [1].
Over the past few decades, the incidence of PAS has been gradually
rising, albeit rates differ by country. Increased rates of caesarean deliveries,
advanced mother age, multiparty, prior uterine surgeries, and placenta praevia
are all contributing risks. It is essential to comprehend these risk factors in
order to identify PAS early and treat it appropriately. Clinical symptoms, such
as aberrant placentation or a history of risk factors, are frequently used to
suspect PAS. However, imaging techniques like magnetic Resonance Imaging
(MRI) and ultrasonography are usually needed for a conclusive diagnosis.
These instruments support the assessment of placental invasion and serve
as a guide for future therapeutic choices. The degree of placental invasion,
gestational age, maternal health, and the desire for future fertility are some
of the variables that affect how PAS is managed. The main objectives of
management are to minimize maternal morbidity, maintain fertility if feasible,
and maximize mother outcomes [2].
Comprehensive counseling of the risks and potential management choices
is made possible by early detection of PAS. Planning the delivery is essential to
reducing hemorrhagic complications. In extreme circumstances, a caesarean
hysterectomy might be advised; this procedure should ideally be carried out in
facilities that are trained to execute intricate obstetric procedures. To lessen
intraoperative bleeding during delivery, preventive Internal Iliac Artery Balloon
Catheterization (IIABC) and selective arterial embolization may be taken into
consideration. To achieve the best results, obstetricians, anesthesiologists,
and surgical specialists work together during intraoperative management.
When possible, methods such bladder flap dissection, progressive
placental excision, and uterine artery ligation are used to reduce blood loss
and maintain fertility. Blood products ought to be easily accessible, and
methods such administering tranexamic acid and cell salvage could be used
to lessen the need for allogeneic transfusions. In an intensive care unit, close
postoperative monitoring is frequently necessary, especially when there
is substantial bleeding or hemodynamic instability. For the best recovery, problems like infection, urological damage, and Disseminated Intravascular Coagulation (DIC) must be identified and treated as soon as possible. PAS is still linked to a high rate of maternal morbidity and mortality, even with improvements in obstetric and surgical care. Hemorrhage, hysterectomy, bladder damage, and the requirement for blood transfusions are frequent complications. Pelvic adhesions, infertility, and the requirement for additional cesarean deliveries are examples of long-term consequences. However, maternal outcomes can be enhanced and, in certain situations, fertility preservation can be maximized with prompt diagnosis, suitable treatment, and access to specialized care. Continued research into the pathophysiology, risk factors, and optimal management strategies for PAS is essential. This includes the development of novel imaging techniques for early diagnosis, refinement of surgical techniques to minimize morbidity, and exploration of adjunct therapies to improve outcomes.
In modern obstetrics, placenta accreta spectrum disorders provide a
serious problem that calls for a multidisciplinary strategy to manage. Improving
maternal outcomes and maintaining fertility need early detection, thorough
prenatal counseling, and prompt intervention. To reduce the morbidity linked
to PAS and enhance the long-term health of impacted women, obstetricians,
surgical specialists, and ancillary support services must continue to work
together.
