[ADRENAL HEMORRHAGE: 6 CASES AND A REVIEW OF 57 REPORTED CASES].

PURPOSE: The guidelines on adrenal hemorrhage has not established in Japan. In this article, we discuss the management of adrenal hemorrhage. OBJECTS AND METHODS: We experienced 6 patients from November 2004 to September 2013 in The University of Tokyo Hospital and The Fraternity Memorial Hospital, and we searched 57 cases already reported in Japan by using Japan Medical Abstracts Society (http://search.jamas.or.jp/). So we analyzed total 63 adrenal hemorrhage cases in Japan. RESULTS: In 63 cases, 5 cases were performed TAE, 3 cases were performed emergent surgeries, 13 cases were managed conservatively and elective surgeries were performed in the other cases. 5 cases were fulfilled criteria for Hb < 10 g/dl and the maximum diameter of the hematoma > 10 cm. Of 5 cases, 4 cases were performed emergent hemostasis. CONCLUSIONS: Adrenal hemorrhages caused by metastatic tumor tend to be serious anemia. In addition, the most patients with adrenal hemorrhages, who had Hb < 10 g/dl and the maximum diameter of the hematoma > 10 cm, required immediate medical treatment, e.g. TAE or surgical hemostasis.
