Pseudoaneurysm formation is a recognized complication of arterial catheterization or traumatic arterial disruption, which may lead to considerable morbidity. Ultrasound-guided thrombin injection has been shown to be effective in the treatment of peripheral pseudoaneurysms; however, its application in the management of radial or ulnar artery pseudoaneurysms has not been well established. Arterial thrombosis and distal embolization are concerns when treating a pseudoaneurysm involving a small vessel. We performed successful ultrasound-guided thrombin injection of a 3-cm radial artery and a 2.5-cm ulnar artery pseudoaneurysm resulting from arterial catheterization and missed arterial trauma, respectively. Radial artery recannalization occurred 28 days after the procedure whereas the ulnar artery remained patent throughout the observation period.
假性动脉瘤形成是动脉插管或外伤性动脉破裂公认的并发症，可能导致相当大的发病率。超声引导下注射凝血酶已被证明对外周假性动脉瘤的治疗有效；然而，其在桡动脉或尺动脉假性动脉瘤管理中的应用尚未得到充分确立。在治疗涉及小血管的假性动脉瘤时，动脉血栓形成和远端栓塞是需要关注的问题。我们分别对因动脉插管和动脉创伤遗漏导致的3厘米桡动脉假性动脉瘤和2.5厘米尺动脉假性动脉瘤成功进行了超声引导下凝血酶注射。术后28天桡动脉再通，而在整个观察期内尺动脉保持通畅。
