Uterine artery pseudoaneurysm following cesarean section; a case report

Uterine artery pseudoaneurysm is an uncommon cause of vaginal bleeding that can occur after cesarean, hysterectomy, myomectomy, uncomplicated vaginal delivery, as well as gynecologic surgery. A 29-year-old woman (G4P1122) who underwent stat cesarean section and intrauterine device placement was found to have a 1.6-cm left uterine artery pseudoaneurysm on follow-up ultrasound. The patient presented to interventional radiology for angiography and uterine artery embolization to minimize the risk of spontaneous hemorrhage. This is the rare reported case, to our knowledge, of a uterine artery pseudoaneurysm associated with a recent cesarean section. Computed tomography angiogram, with multiplanar and maximal intensity projection images, can optimally display the pseudoaneurysm and the feeding vessel, which can provide valuable information for image-guided catheter embolization.
