1. INTRODUCTION
Pre-eclampsia is one of the most common complications
in obstetrics. The exact etiology is unknown, but it is
associated with a failure of the trophoblastic invasion of the
spiral arteries. Current hypothesis is that pre-eclampsia is a
two stage disorder, stage 1 caused by faulty endovascular
trophoblastic remodeling that downstream causes the stage 2
clinical syndrome [1]. An early detection of this complication
may pave the way to an improvement in pregnancy outcome
by increasing the patient’s surveillance or allowing an early
initiation of appropriate therapeutic interventions
