A view of maternal mortalities in women conceiving through assisted reproductive techniques: A nation-based study of Turkey.

BACKGROUND: Our aim was to evaluate maternal mortality causes among Turkish women giving birth after assisted reproductive techniques (ARTs). METHODS: All maternal deaths following conception with ART pregnancies were identified through the National Maternal Mortality Surveillance System. We analyzed the system data collected between 2007 and 2014. During this period, there were 10,369,064 live births and 1788 maternal deaths resulting from both direct and indirect causes. We identified 28 maternal death cases following ART procedures. The age, gestational age at birth, number of antenatal visits, delivery route, time of death, cause of death, and neonatal outcomes were recorded. Also, any existing delay (phase 1, 2, or 3) and preventability of maternal death were assessed. RESULTS: Hypertensive disorders, pulmonary embolism, and cardiovascular disease were the leading causes of maternal death. Twelve (40%) women were over 35 years of age. Of the deaths, 15 (54%) were attributed to indirect causes. The number of unpreventable maternal deaths was 19 (67.9%), and 9 (36%) were classified as preventable after being assessed by the review commission of maternal mortality. CONCLUSION: Pregnancies conceived with ARTs should undergo a careful assessment of risk factors for hypertensive disorders, pulmonary embolism and cardiovascular diseases. Those women require closer antenatal surveillance because 1/3 of these deaths were preventable.

Maternal mortality due to hypertensive disorders in pregnancy, childbirth, and the puerperium between 2012 and 2015 in Turkey: A nation-based study.

OBJECTIVE: To analyze maternal deaths in Turkey due to hypertensive disorders. MATERIAL AND METHODS: In this retrospective study 812 maternal deaths were analyzed. Maternal demographic features, presence of antenatal care, medical and obstetric history, mode of delivery, and use emergency antihypertensive therapy were recorded. The delay model for each case was investigated. RESULTS: Hypertensive disorders accounted for 15.5% (n=126) out of all maternal mortality. They were the third most frequent cause among all causes and the 2nd among direct causes of maternal deaths. Sixty-one (48.4%) cases were in severe preeclampsia or pre-existing hypertensive disorder with increased/superimposed proteinuria, 30.1% were in eclampsia, 9.5% cases were diagnosed as hemolysis, elevated liver enzymes, low platelet count syndrome, and 11.1% in pre-existing hypertension complicating pregnancy, childbirth, and puerperium without increased or superimposed proteinuria. The median age was 32 years, 37.3% women were ≥35 years. All deaths except for 2 cases occurred during the postpartum period. Twenty-three percent of deaths occurred in the first 48 hours postpartum, and 51.6% between 8-42 days. Intracranial hemorrhage was the major final cause of death with a rate of 41.3%. With the exception of fifteen patients with intracranial hemorrhage, emergency antihypertensive agents were not implemented in optimal dose and/or duration. A first and/or third delay was identified in 36.5% of cases. CONCLUSION: Approximately one third of maternal death due to hypertensive disorders could be prevented. The importance of acute antihypertensive treatment should be emphasized because of most frequent cause of death was intracranial hemorrhage.
