About
Placenta accreta rates are rising alongside the rising rates of caesarean deliveries. This has lead to a vast number of studies negotiating the histopathological nature, risk factors and outcomes of pregnancies complicated with placenta accreta. In the study the investigators re discussing the outcome of different plans of management of placenta accreta, namely caesarean hysterectomy and focal myometrium resection.
Full description
Rising rates of caesarean delivery worldwide and especially in Egypt have affected higher rates of placenta accreta spectrum disorders. The increasing prevalence of this life-threatening condition can be primarily prevented by efforts targeted at reducing primary caesarean deliveries as well as encouraging trial of labor after caesarean deliveries of carefully selected gravidas in well-equipped hospitals, capable of providing continuous electronic fetal heart rate monitoring, along with offering one to one health care based systems with the capability of performing emergency caesarean deliveries when needed. As for secondary prevention, the best surgical approach to uterine incisions in caesarean deliveries is yet to be found and universally applied. The said approach will aim at decreasing short and long term complications of uterine scarification resulting in decreased number of placenta accreta cases and possibly downgrading their difficulty, too. Having failed to prevent such occurrence, optimization of PAS management can be attempted to try and decrease implicated injuries. As previously noted, multidisciplinary systematic approach of managing placenta accreta spectrum disorders is indispensable to reduce maternal morbidity and mortality afflicted by this grave condition. The said approach begins with identification of the risk factors of PAS occurrence, calculating pretest probability of PAS and thus early suspicion and referral can be offered by the widely applicable 2nd trimester anomaly scan. After confirming the diagnosis in the 3rd trimester, birthing plans are formulated according to the gravity of the condition assessed by the patient's clinical condition, the ultrasound scan signs, together with social factors as proximity to a healthcare facility capable of offering such management alongside the maternal take on prolonged hospitalization. Decision making and choosing the place of delivery is shared between the pregnant lady, her birth companion and her following up obstetrician. Since elective management of such cases has been proven to be associated with less adjacent organ injuries and associated morbidities, late preterm delivery is usually elected after a course of antenatal corticosteroids as per local protocol.
Guidelines concerned with PAS management still consider caesarean hysterectomy as the main management of placenta accreta disorders. Owing to the high rate of associated morbidity with caesarean hysterectomy, different researchers are hunting down updated recent management approaches with less morbidity and mortality.
Our study evaluated different outcomes with conservative management of placenta accreta spectrum disorders, namely, focal myometrium resection of the adherent defective myometrium along with its overlying placenta after devascularization, as opposed to caesarean hysterectomy. Data will be observed in a total of 36 PAS patients managed in the OBGYN department, in Kasr Al-Ainy School of medicine hospital, with 18 patients undergoing the previously explained conservative management and 18 patients undergoing caesarean hysterectomy. Demographic data of both study groups, alongside operative time, adjacent organ injury estimated blood loss, need for blood transfusion, Inotropic support and ICU admission will be collected, recorded and analyzed.
