Abstract
OBJECTIVE: To assess the safety and efficacy of transcatheter arterial embolization (TAE) of the inferior mesenteric artery (IMA) for the management of post-partum hemorrhage (PPH). METHODS: A retrospective analysis was performed regarding eight patients (mean age, 34.4 y; age range, 31 - 40 y) who underwent TAE of the IMA for PPH between March 2001 and September 2018. Obstetric records, including maternal characteristics, clinical manifestations, complications, and clinical outcomes, as well as TAE details were obtained. RESULTS: All eight patients had primary PPH and the vaginal delivery mode. CT scans of two patients showed active bleeding from the lower uterus or hematoma and with the origin of contrast extravasation abutting the adjacent rectum. In seven patients, an aortogram or IMA arteriogram following persistent vaginal bleeding after sufficient embolization of the bleeding focus from the bilateral iliac arteries, found the bleeding focus of the IMA, while in one patient, the IMA bleeding focus was found at the second session 4 h after the first session. TAE of the IMA was technically successful in all eight patients and cessation of bleeding without repeated TAE or additional hemostatic surgery was achieved in all patients after TAE of the IMA. There were neither procedure-related complications nor bowel ischemia during follow-up. CONCLUSION: TAE of the IMA for PPH was safe and effective with successful hemostasis. Bleeding from the IMA should be suspected when there is persistent vaginal bleeding after sufficient embolization of bleeders from the bilateral iliac arteries. ADVANCES IN KNOWLEDGE: Bleeding from the IMA should be suspected when there is persistent vaginal bleeding after sufficient embolization of bleeders from the bilateral iliac arteries.
