Severe pre-eclampsia is a significant risk factor for intrauterine fetal death. A rise in baseline blood pressure (BP) of 30 mmHg systolic or 15 mmHg diastolic, while not meeting the absolute criteria of 140/90, is important to note but is not considered diagnostic.
Disseminated intravascular coagulation (DIC) is a condition in which blood clots form throughout the body, blocking small blood vessels. [1] Symptoms may include chest pain, shortness of breath, leg pain, problems speaking, or problems moving parts of the body. [1] As clotting factors and platelets are used up, bleeding may occur. [1]
The federal guidelines recommend reporting those fetal deaths whose birth weight is over 12.5 oz (350 g), or those more than 20 weeks gestation. [63] Forty-one areas use a definition very similar to the federal definition, thirteen areas use a shortened definition of fetal death, and three areas have no formal definition of fetal death.
A placental abruption caused by arterial bleeding at the center of the placenta leads to sudden development of severe symptoms and life-threatening conditions including fetal heart rate abnormalities, severe maternal hemorrhage, and disseminated intravascular coagulation (DIC).
Placental syndromes include pregnancy loss, fetal growth restriction, preeclampsia, preterm delivery, premature rupture of membranes, placental abruption and intrauterine fetal demise. [ 7 ] Signs and symptoms
Spontaneous fetal termination after 20 weeks of gestation is known as a stillbirth. [15] The term miscarriage is sometimes used to refer to all forms of pregnancy loss and pregnancy with abortive outcomes before 20 weeks of gestation. The most common symptom of a miscarriage is vaginal bleeding, with or without pain. [1]
Antithrombin III deficiency (abbreviated ATIII deficiency) is a deficiency of antithrombin III.This deficiency may be inherited or acquired. [1] It is a rare hereditary disorder that generally comes to light when a patient suffers recurrent venous thrombosis and pulmonary embolism, and repetitive intrauterine fetal death (IUFD). [2]
Fetal mortality refers to stillbirths or fetal death. [9] It encompasses any death of a fetus after 20 weeks of gestation or 500 gm. In some definitions of the PNM early fetal mortality (week 20–27 gestation) is not included, and the PNM may only include late fetal death and neonatal death.
