All are true about pre eclampsia except:
Severe complications of Preeclampsia:

Pulmonary edema


It is a common complication of severe preeclampsia and eclampsia affecting ~3% of patients.
Most cases are a result of aggressive use of crystalloid solutions, for intravascular volume expansion
It usually occurs in the post partum period and is characterized by profound respiratory distress, severe hypoxemia and diffuse rales.

Treatment:

Administering oxygen by nasal prongs.
Restriction of I/V or oral fluids.
Furosemide 20-40 mg l/v every 6 hours.


Acute renal Failure:


Oliguria is common in patients with severe preeclampsia
It is mostly prerenal in origin.


Intracranial bleeding: It is the leading cause of death in preeclampsia. It is seen that main connection of this event is with systolic BP and not with diastolic B/P.
Visual disorder: Blindness may occur in patients with severe preeclampsia and eclampsia and may persist for several days, although quick recovery after delivery is the rule.

As far as DVT is concerned – I know some of you may think that DIC is a result of preeclampsia which in turn can lead to DVT – But –
DIC is a complication of eclampsia and HELLP syndrome, perse preeclampsia does not lead to DIC. Only if preeclampsia is associated with abruption of placenta it leads to DIC,
Read the following lines from COGDT 10/e, p 997
“Eclampsia is associated with DIC 11% of the time, with HELLP syndrome this increases to 15%. Peeclampsia together with placental abruption also significantly increases this association.”
