Pseudoaneurysm is a known complication of penetrating arterial injuries such as catheterization, gunshot wounds, and open fractures. Vaccination is an effective method for preventing multiple, serious, infectious diseases in children. Common adverse reactions related to vaccination include fever, swelling, redness, and pain. Brachial pseudoaneurysm after vaccination has not been previously reported.
Herein we describe a novel case of brachial pseudoaneurysm after vaccination in a child aged 1 year and 3 months. A pulsatile mass was formed in the medial left arm of the infant 10 days after vaccination at a community hospital and gradually grew larger. Preoperative images depicted an eccentric aneurysm in the brachial artery and a swirling flow pattern in the mass. The pseudoaneurysm was excised, and vein graft interpositioning was successfully performed. There were no short-term or long-term complications during the follow-up period.
Brachial pseudoaneurysm is a rare complication of vaccination via intramuscular injection. Medical staff should avoid puncture wounds to the brachial artery during vaccination, especially in infants.
假性动脉瘤是已知的穿透性动脉损伤的并发症，如导管插入术、枪伤和开放性骨折。疫苗接种是预防儿童多种严重传染病的有效方法。与疫苗接种相关的常见不良反应包括发热、肿胀、发红和疼痛。接种疫苗后发生肱动脉假性动脉瘤尚未见报道。
在此，我们描述了一例 1 岁零 3 个月儿童接种疫苗后发生肱动脉假性动脉瘤的新病例。在社区医院接种疫苗 10 天后，婴儿的左手臂内侧形成了一个搏动性肿块，并逐渐增大。术前图像显示肱动脉偏心性动脉瘤和肿块内漩涡状血流模式。假性动脉瘤被切除，并成功进行了静脉移植物间置。在随访期间没有出现短期或长期并发症。
肱动脉假性动脉瘤是肌肉内注射疫苗的罕见并发症。医务人员在接种疫苗时应避免肱动脉刺伤，尤其是在婴儿中。
