Intercostal artery pseudoaneurysm is an exceedingly rare complication seen after chest wall insult, either through trauma or operative procedures. We present a case of a 74-year-old man with mitral regurgitation and aortic stenosis who underwent aortic and mitral valve replacement via sternotomy. At the 1-month follow-up, a 1-cm pulsatile mass was noted adjacent to the left of the sternotomy in the sixth intercostal space. Concern for a pseudoaneurysm of the intercostal artery prompted evaluation with ultrasound, which demonstrated a pseudoaneurysm originating from an intercostal artery. This unusually located pseudoaneurysm was treated with ultrasound-guided thrombin injection with complete resolution.
肋间动脉假性动脉瘤是一种极为罕见的并发症，见于胸壁受创后，无论是外伤还是手术操作所致。我们报告一例74岁男性患者，患有二尖瓣反流和主动脉瓣狭窄，接受了经胸骨切开术的主动脉瓣和二尖瓣置换术。在术后1个月的随访中，在胸骨切开处左侧第六肋间发现一个1厘米的搏动性肿块。考虑为肋间动脉假性动脉瘤，遂行超声检查，结果显示为起源于肋间动脉的假性动脉瘤。这个位置异常的假性动脉瘤通过超声引导下注射凝血酶进行治疗，最终完全消退。
