Superselective microcoil embolization of the vasa recta of sigmoid artery for hemorrhaging after laparoscopic adnexectomy for corpus luteum hematoma with severe adhesion

: A 44-year-old multipara woman was referred because of the sudden onset of left lower abdominal pain. Corpus luteum hematoma was suspected and conservatively managed. Two days later, due to worsening of abdominal symptoms, emergency laparoscopic surgery was performed. Severe pelvic adhesion around the left ovary forming corpus luteum hematoma was identified. After adhesiolysis, which was complicated by massive bleeding, left adnexectomy was performed. Hemostasis was achieved by the coagulation of bleeding vessels, followed by spraying fibrin glue with the placement of oxidized cellulose cotton for bleeding oozing from dissected surface. Two hours after surgery, emergency computed tomography performed due to the development of hemodynamic instability demonstrated extravasation from the versa recta of the sigmoid artery. After the confirmation of hemorrhaging, superselective catheterization to the bleeding vessel followed by embolization by platinum microcoils were performed. Hemodynamic stability was immediately achieved, and the postoperative course was uneventful without manifestation of bowel ischemia.
