68
Q

Underlying mechanism in all cases of preeclampsia syndromes

A

Inadequate maternal blood flow to the placenta due to inadequate development of spiral arteries

69
Q

Why do pre-eclamptic patients have high BP?

A

Placental hypoperfusion leads to decreased placental production of vasodilators (prostacyclin, NO, prostaglandin E2), which oppose RAAS.

70
Q

Why are pre-eclamptic patients at high risk of developing DIC?

A

The ischemic placenta secretes tissue factor and thromboxane.

71
Q

What are the placental changes noted in patients with pre-eclampsia/eclampsia?
