Introduction: Placenta accreta spectrum (PAS) is a serious condition with a mortality as high as 7%. However, the factors associated with this type of death have not been adequately described, with an almost complete lack of publications analyzing the determining factors of death in this disease. The aim of our work is to describe the causes of death related to PAS and to analyze the associated diagnosis and treatment problems. Material and methods: This is an inter-continental, multicenter, descriptive, retrospective study in low-and middle-income countries. Maternal deaths related to PAS between January 2015 and December 2020 were included. Crucial points in the management of PAS, including prenatal diagnosis and details of the surgical treatment and postoperative management, were evaluated. | 1453 NIETO-CALVACHE ET AL.

Placenta accreta spectrum (PAS) quality care demands abundant health resources, including trained surgical teams. Although surgeon training is related to better clinical results 1 and improper surgical techniques are associated with death due to PAS, 2 training in the management of this disease is challenging because no specific educational programs exist and the flow of patients is variable, even at specialized centers.
