It affects 4-6% of placentas sent to pathologists for examination.16 The syndrome encompasses the following histopathological lesions and terms: Other contributing factors may include maternal The term fetal vascular malperfusion (FVM) is used to describe placental pathology that is throught to result from an obstruction in fetal blood flow that could result from a number of conditions (eg, umbilical cord lesions, hypercoagulability, complications of fetal cardiac dysfunction, such as hypoxia, etc.). Abnormally long and hypercoiled umbilical cords are associated with an increased risk of umbilical cord blood flow restriction, which in turn can result in adverse perinatal and maternal outcomes. Intrauterine fetal demise due to fetal vascular malperfusion in mid-gestation is a rare occurrence.

Hypo- or hyperechoic, well-circumscribed mass, which is usually located underneath the chorionic plate near the umbilical cord insertion, and often protrudes into the amniotic cavity. Abnormally long and hypercoiled umbilical cords are associated with an increased risk o.
