Chorangiosis is a placental pathology characterized by an abundance of blood vessels within the chorionic villi.
Associations
It is associated with gestational diabetes,[1] smoking and high altitude.
Diagnosis
It is diagnosed by a microscopic examination of the placenta.
Commonly used criteria from Altshuler[2][3] are: "a minimum of 10 villi, each with 10 or more vascular channels, in 10 or more areas of 3 or more random, non-infarcted placental areas when using a ×10 ocular." The Altshuler criteria are not theoretically rigorous, as they do not define the area. Normal villi have up to five vascular channels.[3]
