title: Gestational vascular complications.
abstract: Severe pregnancy complications, primarily severe pre-eclampsia, placental abruption, intrauterine growth restriction (IUGR) and intrauterine fetal death (IUFD) occur in about 1-5% of gestations. This rate is even higher in special medical situations. These pregnancy complications have been shown to increase maternal and fetal morbidity and mortality considerably. Severe pregnancy complications have also been shown to be associated with deficient uteroplacental circulation and are linked with intervillous and spiral vessel thrombosis. Moreover, it has been suggested that these complications could have their basis in a deficient trophoblast invasion in the uterine spiral arteries at a stage much earlier than the clinical manifestations become evident. In the last few years, evidence has accumulated to suggest that severe pregnancy complications could have a common thrombogenic basis associated with inherited and acquired thrombophilia. In this chapter we present a comprehensive update of the aetiology, pathophysiology, clinical manifestations, diagnosis and treatment of these severe pregnancy complications.
