“…Based on our experience and the literature, it should be possible, especially for placenta increta or percreta [8,15,21] . The placental implantation site must be explored carefully, especially when the placental insertion is anterior and previa and the patient has undergone a previous cesarean delivery.…”

Objective: Placenta increta or percreta is an uncommon pathology, sometimes associated with high maternal morbidity. Its prevalence increases proportionally to the number of cesarean sections. This study analyzed the changes of our management strategy to devise treatment guidelines for this uncommon disorder. Materials and methodology: Between 2005 and 2011, 10 cases of placenta increta or percreta were managed at our university hospital maternity department. Results: Among the 10 cases, seven were diagnosed prenatally. Two patients were diagnosed early, at 14 and 17 weeks of gestational age, and their pregnancies were terminated. Five had hysterectomies during the intrapartum period, and despite attempted conservative treatment for the two others, hysterectomy proved necessary 2 months postpartum because of intrauterine infections. Seven of the 10 women had hysterectomies. Conclusion: Prenatal diagnosis of placenta increta or percreta is essential to plan the delivery in a competent tertiary care center. The decision to perform a cesarean hysterectomy or leave the placenta in situ for spontaneous delivery is based on the extent of infi ltration, the patient ' s hemodynamic status, and her desire to remain fertile. The high-risk of infection and severe hemorrhage must not be overlooked should conservative treatment be chosen. This situation requires prolonged close monitoring.

“…In addition, Shi et al (39) found that the most prominent grayscale sign to diagnose placenta accreta was dilated vessels extending from the placenta to the myometrium, and the most prominent color Doppler diagnostic sign was the presence of abnormal vessels connecting the placenta to the bladder. Shi et al (40) found that numerous vessels observed by the 3D power Doppler was the best single diagnostic sign of placenta accreta, with 97% sensitivity, and they concluded that the 3D power Doppler is a useful tool for the diagnosis of MAP. Chou et al (12) found that the (41) found that irregular tortuous vessels affecting the entire placenta and the uterine serosa-bladder interface were the diagnostic signs of MAP observed by the 3D power Doppler.…”

Placenta accreta occurs when placental trophoblasts invade the endometrium beyond the Nitabuch's layer of decidua basalis, placenta increta occurs when placental trophoblasts invade the myometrium, and placenta percreta occurs when placental trophoblasts invade the serosa (1, 2). Morbid adherent placenta (MAP) is generally associated with excess blood loss, bladder injuries and hysterectomies (3, 4). The incidence of MAP has increased significantly over the last 50 years (5, 6). A past history of a cesarean delivery, placenta previa, and damage of the Nitabuch's layer of decidua basalis following intrauterine infection or scarring are the risk factors of MAP. The incidence of MAP is increased concomitantly with increased cesarean section rates (1, 7-9). The incidence of MAP is 3.3% in pregnant women with no past history of cesarean delivery and placenta previa and is 40% in pregnant women with a history of two cesarean sections and placenta previa (4). If MAP was diagnosed or suspected before delivery, the optimum time for planned delivery is around 34-35 weeks, following a course of corticosteroids and multidisciplinary team care approach (2, 10, 11). An accurate diagnosis of MAP is essential to prepare both the patient and health providers for possible complications during delivery. Authors reported that ultrasound is a useful tool to diagnose MAP, with 77%-93% sensitivity and 71%-98% specificity (12-16). Moodley et al. (17) concluded that the color flow Doppler was more specific, with a 95% negative predictive value (NPV) in the prenatal diagnosis of MAP, than magnetic resonance imaging (MRI), and MRI should be reserved for cases with inconclusive sonographic findings (13,15,17). The sonographic markers of placenta accreta can be seen in the first trimester of pregnancy in the form of low implantation of the pregnancy sac and multiple vascular spaces within the placenta (2). Prenatal diagnosis of MAP with gray-scale and Doppler sonography allows the development of the multidisciplinary team care approach during delivery (14). This current study aimed Objective: To detect the accuracy of the three-dimensional multislice view (3D MSV) Doppler in the diagnosis of morbid adherent placenta (MAP). Material and Methods:Fifty pregnant women at ≥28 weeks gestation with suspected MAP were included in this prospective study. Two dimensional (2D) trans-abdominal gray-scale ultrasound scan was performed for the subjects to confirm the gestational age, placental location, and findings suggestive of MAP, followed by the 3D power Doppler and then the 3D MSV Doppler to confirm the diagnosis of MAP. Intraoperative findings and histopathology results of removed uteri in cases managed by emergency hysterectomy were compared with preoperative sonographic findings to detect the accuracy of the 3D MSV Doppler in the diagnosis of MAP. Results:The 3D MSV Doppler increased the accuracy and predictive values of the diagnostic criteria of MAP compared with the 3D power Doppler. The sensitivity and negative predictive value (NPV) (79.6%...

“…Shih et al [3] have reported that three-dimensional power Doppler signs had a sensitivity of 100 % and a specificity of 85 % when at least one of the three criteria was present, i.e., confluent vessels between bladder and uterine serosa, hypervascularity on lateral view and inseparable cotyledonal and intervillous circulations with chaotic appearance.…”
