Hypertrophic decidual vasculopathy, also known as decidual vasculopathy, is a pathology of the placenta seen in the context of (gestational) hypertension.
General
- A change seen in hypertension.
- Seen in intrauterine growth restriction (IUGR).
Microscopic
Features:[1]
- Mild or moderate:
- Perivascular inflammatory cells.
- +/-Vascular thrombosis.
- Smooth muscle hypertrophy.
- Endothelial hyperplasia.
- Above two lead to narrowing of the decidual spiral arteries[2] -- key feature.
- Severe:[1]
- Atherosis of maternal blood vessels.
- Foamy macrophages within vascular wall.
- Fibrinoid necrosis of vessel wall (amorphous eosinophilic material vessel wall).
- Atherosis of maternal blood vessels.
- Suggestive:[3]
- Decidual vasculitis - lymphocyte predominant without plasma cells.
Note:
- Smooth muscle hypertrophy can also be understood as lack of physiological conversion of spiral arteries of the uterus.[4]

PLACENTA, UMBILICAL CORD AND FETAL MEMBRANES, CESAREAN SECTION: - DECIDUAL VASCULOPATHY. - PLACENTA SMALL FOR GESTATIONAL AGE (222 GRAMS). - PLACENTAL DISC WITH EARLY THIRD TRIMESTER VILLI WITH: -- MULTIPLE PLACENTAL INFARCTS. -- PERIVILLOUS FIBRIN DEPOSITION. - THREE VESSEL UMBILICAL CORD WITHIN NORMAL LIMITS. - FETAL MEMBRANES WITHIN NORMAL LIMITS. COMMENT: The 10th percentile placental mass (pre-fixation) for 32 weeks and 6 days is approximately 247 grams.
