Unfortunately, I cannot create an abstract of the requested article because the full text of the article titled "Top Causes of Maternal Death May Not Be What You Think" from MedPage Today is not found in the search results provided. Although the article is cited in some documents, its content is not available in its entirety. I can give you information about the causes of maternal deaths based on the World Health Organization data available in my results: the main causes of maternal deaths are heavy bleeding, infections, high blood pressure during pregnancy, complications during childbirth and unsafe abortions. These causes account for approximately 75% of all maternal deaths. If you would like me to create a summary of a particular article, please provide the full text.
