Pseudoaneurysms arise from a disruption in the arterial wall and blood dissecting into the tissues around the damaged artery creating a perfused sac that communicates with the arterial lumen. Trauma to the wall of the artery may lead to the development of a pseudoaneurysm. Post-traumatic pseudoaneurysm development is very rare in the peripheral artery and often is a consequence of venipuncture. We have reported the case of the four-month-old boy who developed a pseudoaneurysm following an accidental arterial puncture. In the antecubital area we noticed a pulsative mass and palpable thrill. The patient underwent a Doppler ultrasound examination and CT with contrast. Surgery was indicated. Following excision of the pseudoaneurysm, an end-to-end anastomosis was performed. Follow-up for four years revealed palpable peripheral pulsation at the wrist level. In the postoperative period, all ultrasound findings were normal. End-to-end anastomosis is preferable if it can be performed without tension or damage to the major collateral vessels.
假性动脉瘤是由于动脉壁破裂，血液流入受损动脉周围的组织中，形成一个与动脉腔相通的充满血液的囊袋。动脉壁的创伤可能导致假性动脉瘤的形成。在外周动脉中，创伤后假性动脉瘤的发展非常罕见，通常是静脉穿刺的后果。我们报告了一例 4 个月大的男孩，他在一次意外的动脉穿刺后出现了假性动脉瘤。在前臂区域，我们注意到一个搏动性肿块和可触及的震颤。患者接受了多普勒超声检查和 CT 增强扫描。手术指征明确。假性动脉瘤切除后，进行了端端吻合术。随访 4 年，发现手腕水平可触及外周搏动。术后所有超声检查结果均正常。如果可以无张力或不损伤主要侧支血管进行端端吻合，则更为理想。
