Why the study?
Uterine artery pseudoaneurysm is an uncommon cause of vaginal bleeding following cesarean section or other gynecologic procedures.
This case highlights the utility of CT angiography and uterine artery embolization in the diagnosis and management of a rare uterine artery pseudoaneurysm following cesarean section.
Supports vigilance for uterine artery pseudoaneurysm in postpartum bleeding; hypothesis-generating for embolization protocols.
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.
