Postpartum hemorrhage is the most common cause of maternal morbidity in the United States. However, secondary postpartum hemorrhage is rare and includes pseudoaneurysms, which represent only 3.3% of all cases of secondary postpartum hemorrhage. Vulvar labial artery pseudoaneurysm had never been reported in the literature.
This is a case of ruptured vulvar labial pseudoaneurysm leading to secondary postpartum hemorrhage. Computerized tomography angiography showed it to be located in a distal branch of the vulvar labial artery. This location is unique, although there are reported cases of pseudoaneurysms in the uterine artery. The patient was successfully treated with arterial embolization.
Recognition of a ruptured pseudoaneurysm as the cause of postpartum hemorrhage allows for its proper management by arterial embolization.
产后出血是美国孕产妇发病的最常见原因。然而，继发性产后出血很少见，包括假性动脉瘤，其仅占所有继发性产后出血病例的3.3%。文献中从未报道过外阴唇动脉假性动脉瘤。
这是一例破裂的外阴唇假性动脉瘤导致继发性产后出血的病例。计算机断层血管造影显示其位于外阴唇动脉的远端分支。尽管有子宫动脉假性动脉瘤的报道，但该位置是独特的。该患者通过动脉栓塞成功治疗。
认识到破裂的假性动脉瘤是产后出血的原因，有助于通过动脉栓塞进行适当的处理。
