FERREIRA NARVAEZ, Fidel Ernesto  and  ANGULO CARVALLO, Mónica. Predicting placenta accreta with Doppler ultrasound at the Neiva teaching hospital, Colombia: A cohort study. Rev Colomb Obstet Ginecol [online]. 2007, vol.58, n.4, pp.290-295. ISSN 0034-7434.

Objective: evaluating ultrasonographic findings and maternal and perinatal outcomes for patients with and without accretism who were submitted to antenatal ultrasonographies and Doppler ultrasound. Methods: a cohort of high-risk women was studied for accretism. Foetal Doppler results were compared with outcomes after surgery, the need for hysterectomy, perinatal outcome and clinical evolution following surgery. Results: a total of 51 patients having a high risk of accretism were evaluated. High-probability for accretism was confirmed in 5 patients, whereas low probability was found for 46 patients. Comparing the results in terms of the presence of accretism, there was a 60% hysterectomy rate for the high probability group whereas it was only 2% in the low-probability group. Blood transfusions were necessary in 40% of patients having high-risk of accretism, whereas it was only 2% in the low-probability group. Conclusions: maternal and neonatal complications are more frequent in patients having a high probability of accretism. Prenatal diagnosis of placenta accreta is essential in detecting patients at risk of maternal complications and determining the need for hysterectomy following a caesarean section.
