Cardiac catheterization through the radial artery has reduced the percentage of complications seen previously in the femoral approach. Computed tomographic angiography is a noninvasive technique that can accurately diagnose pseudoaneurysms and other vascular pathologies. A 93-year-old female presented to the emergency department with pain and swelling of her right distal arm and wrist after a transradial cardiac catheterization procedure, as part of a transcatheter aortic valve replacement evaluation for severe aortic stenosis. Angiography is the standard diagnosing technique for aneurysms and pseudoaneurysms, but it is an invasive procedure. We show this case in order to highlight the importance of computed tomographic angiography as a noninvasive approach in diagnosing uncommon complications in the clinical setting.
经桡动脉进行心脏导管插入术已降低了先前经股动脉途径出现的并发症百分比。计算机断层血管造影术是一种无创技术，可准确诊断假性动脉瘤和其他血管病变。一名93岁女性在经桡动脉心脏导管插入术后，因右上肢远端和手腕疼痛肿胀而就诊于急诊科，该导管插入术是对严重主动脉瓣狭窄进行经导管主动脉瓣置换评估的一部分。血管造影术是诊断动脉瘤和假性动脉瘤的标准技术，但它是一种侵入性操作。我们展示此病例是为了强调计算机断层血管造影术作为一种无创方法在临床环境中诊断罕见并发症的重要性。
