Pseudoaneurysm of intercostal artery following laparoscopic nephrectomy is rare. We report a 69-year-old man who developed pseudoaneurysm of intercostal artery 2 months after undergoing laparoscopic right radical nephrectomy. On follow-up, patient presented with an expanding palpable mass under 5-mm trocar wound. Color Doppler ultrasound showed bidirectional blood flow in sac, and dynamic contrast-enhanced CT confirmed the pseudoaneurysm. Aneurysmectomy was performed after ligating proximal feeding artery and confirming the disruption of blood supply into sac on color Doppler ultrasound.
腹腔镜肾切除术后肋间动脉假性动脉瘤较为罕见。我们报告一名69岁男性，在接受腹腔镜右根治性肾切除术后2个月发生了肋间动脉假性动脉瘤。随访时，患者在5毫米套管针伤口下方出现一个可触及的、不断增大的肿块。彩色多普勒超声显示瘤腔内有双向血流，动态对比增强CT证实了假性动脉瘤。在结扎近端供血动脉并经彩色多普勒超声确认瘤腔内血供中断后，进行了动脉瘤切除术。
