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.
子宫动脉假性动脉瘤是剖宫产、子宫切除术、子宫肌瘤切除术、顺产及妇科手术后阴道出血的罕见原因。一名29岁女性（孕4产1122）急诊剖宫产术后放置宫内节育器，随访超声检查发现左侧子宫动脉有一个1.6厘米的假性动脉瘤。患者前往介入放射科进行血管造影和子宫动脉栓塞术，以降低自发性出血风险。据我们所知，这是罕见的与近期剖宫产相关的子宫动脉假性动脉瘤病例报告。计算机断层血管造影结合多平面和最大密度投影图像，能够最佳地显示假性动脉瘤及其供血血管，可为影像引导下的导管栓塞术提供有价值的信息。
