Hypertrophic decidual vasculopathy
Diagnosis in short

Hypertrophic decidual vasculopathy. H&E stain.
Synonyms decidual vasculopathy
LM mild or moderate: perivascular inflammatory cells, +/-vascular thrombosis, smooth muscle hypertrophy, endothelial hyperplasia; severe: atherosis of maternal blood vessels, foamy macrophages within vascular wall, fibrinoid necrosis of vessel wall
Site placenta
Associated Dx intrauterine growth restriction
Signs hypertension
Prevalence uncommon
Clin. DDx gestational hypertension, HELLP syndrome
Treatment dependent on severity

Hypertrophic decidual vasculopathy, also known as decidual vasculopathy, is a pathology of the placenta seen in the context of (gestational) hypertension.

General

Microscopic

Features:[1]

  • Mild or moderate:
    1. Perivascular inflammatory cells.
    2. +/-Vascular thrombosis.
    3. Smooth muscle hypertrophy.
    4. Endothelial hyperplasia.
      • Above two lead to narrowing of the decidual spiral arteries[2] -- key feature.
  • Severe:[1]
    1. Atherosis of maternal blood vessels.
      • Foamy macrophages within vascular wall.
    2. Fibrinoid necrosis of vessel wall (amorphous eosinophilic material vessel wall).
  • 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]
