“…Kastner et al found that the rates of placenta creta were 35, 56, 75, and 100% after zero, one, two, and more than two CSs, respectively (15). Chou et al identified 14 patients with a histologically proven placenta accreta, of which seven (50%) had had a previous CS (16). In our smaller study, the incidence of placenta creta was 20, 10, and 70%, after zero, one, and two or more CSs, respectively.…”

“…In placenta creta cases, remodeling of the larger radial and arcuate arteries is seen (3). In these arteries, the loss of muscular and elastic tissue render them unresponsive to vasospasm because of their larger diameter and greater blood flow compared to the smaller diameter spiral arteries (3,9,16). Thus, when removal of the adherent placenta is attempted, heavy haemorrhage occurs.…”

“…The depiction of turbulent blood flow in placental lacunae and the presence of low-resistance arterial blood flow in the serosa-bladder interface on color Doppler imaging are highly predictive of accreta. 30 If the ultrasound findings are not considered definitive or the placenta is located on the posterior wall or to assess possible bladder involvement, MRI can be performed using gadolinium contrast intravenously. Magnetic resonance imaging findings suggestive of placenta accreta include placental heterogeneity; mass effect of the placenta into the underlying bladder or extending laterally or posteriorly beyond the normal uterine contour; obliteration of the myometrial zone visible on initial uptake of gadolinium and a beading nodu larity within the placenta.…”

The etiology of postpartum hemorrhage (PPH) is diverse and management depends on identifying the cause and tailoring treatment appropriately. The major causes of PPH are uterine atony, endometritis, retained placental tissue, placental abnormalities, i.e. placenta accreta, increta and percreta, sub in volution of the placental implantation site, arteriovenous malfor mation (AVM), lower genital tract trauma, uterine abnor malities, bleeding disorders, coagulopathies and use of anticoagulants. Use of imaging modalities (i.e. ultrasound scanning and color and pulsed Doppler) at an early stage in the search for the etiology of PPH helps to decrease morbidity and mortality.This article reviews the differential diagnoses for bleeding in the postpartum period and assesses the role of ultrasound in the diagnosis and treatment of postpartum bleeding. By using illustrative images, the reader will be able to correlate findings on Bmode, color Doppler and 3D ultrasound in diagnosis and treatment of postpartum bleeding. It is important to be aware of the appearance of normal postpartum uterus to avoid misdiagnosis.

“…8 However, in a small series of 6 cases, Levine et al 5 found that color Doppler imaging added no appreciable information in diagnosing placenta accreta. False-positive diagnoses may occur with these criteria because of technical factors and the presence of bladder varices; therefore, it is important that the examination is made with the proper resolution and focus using both transabdominal and transvaginal transducers.…”

Objective. Placenta accreta is a life-threatening problem that is rising in incidence in the developed world. The increased risk of placenta accreta in women with placenta previa and 1 or more prior cesarean deliveries is well established and prompts careful sonographic evaluation. Our objective was to emphasize that accreta is also identified at sites other than cesarean scars. Methods. Two cases of placenta accreta without placenta previa seen in association with uterine scarring from myomectomy and uterine fibroids are described. Results. The sonographic and magnetic resonance imaging findings of accreta are reviewed in the classic setting of prior cesarean deliveries as well as myomectomy and uterine fibroids. Conclusions. We suggest that when the placenta overlies any uterine abnormality, a careful search for invasive placentation is warranted. Key words: accreta; sonography, fibroids; sonography, placenta. Maternal-Fetal Medicine, University of Ottawa, Ottawa Hospital, Ottawa, Ontario, Canada (A.A.) lacenta accreta occurs when there is a defect in the decidua basalis, allowing the anchoring villi to adhere to the myometrium. The frequency of abnormal placentation has increased 10-fold over the last 20 years and is now observed in 9.3% of women with placenta previa or in 1 per 533 deliveries. Received June 5, 2008, from the Department of1 Cesarean delivery is probably the most common cause of decidual defects, and the increase in placenta accreta may be attributed primarily to the rising cesarean delivery rate, which has risen to greater than 30% in the United States at the time of writing. Among those with previous cesarean deliveries who have placenta previa or a lowlying anterior placenta, the risk of placenta accreta increases from 24% for a single cesarean delivery to 67% for 4 cesarean deliveries.2 Other risk factors for accreta include subserosal uterine myomas, previous myomectomy, Asherman syndrome, maternal age older than 35 years, smoking, and elevated α-fetoprotein levels. 3,4 Massive hemorrhage at the time of delivery is the most important clinical issue in cases of placenta accreta.
