Infarction is the tissue necrosis due to acute blood and oxygen deprivation either to placental membranes or decidua basalis (laminar necrosis) or villous tissue (villous infarction).

The study does not specify if the decidual lymphocyte cells were isolated from decidua basalis or decidua parietalis.
The decidua can be divided into two anatomically different parts; the decidua basalis covers the basal plate of the placenta, while the decidua parietalis lines the fetal membranes.
The factors influencing immune cell composition and activation status in the decidua basalis and parietalis are still poorly characterized, but it is likely that these two sites are differentially influenced by the stromal microenvironment.
MAP occurs when there is a defect in the decidua basalis, resulting in abnormal invasion of the trophoblast into the myometrium.
(4) The diagnosis of abnormal placentation is histological, and reveals the absence or poor development of the decidua basalis associated with varying extents of trophoblasatic villus invasion of the myometrium.
At caesarean, the area of decidua basalis was curetted with uterine curette.
