Aim: To evaluate factors related to the occurrence of Sheehan syndrome. Methods: The obstetrical disseminated intravascular coagulation score, total volume of hemorrhage, shock index, level of consciousness at the time of shock occurrence and pituitary magnetic resonance imaging findings were evaluated in nine women who showed massive hemorrhage during delivery. These clinical outcomes were analyzed in all these patients who were prospectively followed-up to identify any possible occurrence of Sheehan syndrome. Results: Compared to six women with non-Sheehan syndrome, three women who were diagnosed with Sheehan syndrome showed significant elevation of the obstetrical disseminated intravascular coagulation score, decrease in the level of consciousness during shock and remarkable pituitary gland atrophic change with an empty sella turcica detected by pituitary magnetic resonance imaging. The volume of hemorrhage during delivery and shock index were not significantly different between these two groups of women. Conclusion: Careful attention and follow-up should be paid to women with post-partum massive hemorrhage for early detection and management of women with Sheehan syndrome.;開始ページ : 46;終了ページ : 52;元資料の権利情報 : © 2013 Japan Society of Obstetrics and Gynecology.;元資料の権利情報 : The definitive version is available at Wiley Online Library , www.wileyonlinelibrary.com.
