Villi, focally, have increased vascular channels; however, they are the appropriate size, for the gestational age, and have peripheral vessels. | Villi, focally, have increased vascular channels; however, they are the appropriate size, for the gestational age, and have peripheral vessels. | ||

Lack of physiologic conversion (of the spiral arteries of the uterus) is a feature seen in hypertrophic decidual vasculopathy (the histopathologic correlate of gestational hypertension). Other changes of hypertrophic decidual vasculopathy (atherosis, intimal hyperplasia, fibrinoid necrosis of the vessel wall, perivascular inflammation, thrombosis) are absent. | Lack of physiologic conversion (of the spiral arteries of the uterus) is a feature seen in hypertrophic decidual vasculopathy (the histopathologic correlate of gestational hypertension).
