The radial artery as a superficial structure at the wrist is susceptible both to direct penetrating injury and to blunt trauma, with the potential development of both false and true aneurysms. This report summarizes the sonographic features of seven consecutive patients who were referred for evaluation of the radial artery. The diagnoses include two cases of radial artery aneurysm, one tortuous nonaneurysmal artery, two cases of arteriovenous fistulae (one surrounded by fluid and one aneurysmal), a ganglion, and an inflammatory mass of the wrist. Although radial aneurysms are unusual and angiography may be required to define the nature and extent of distal embolization to the hand, the nature of a palpable aneurysm in this region, vascular vs avascular, is easily and quickly assessed with high-resolution sonography.
桡动脉作为腕部的浅表结构，易受直接穿透伤和钝性创伤影响，有形成假性和真性动脉瘤的可能。本报告总结了连续七例因桡动脉评估而转诊患者的超声特征。诊断包括两例桡动脉动脉瘤、一例迂曲的非动脉瘤性动脉、两例动静脉瘘（一例有液性包绕，一例为动脉瘤性）、一个腱鞘囊肿和一例腕部炎性肿块。尽管桡动脉瘤并不常见，可能需要血管造影来确定手部远端栓塞的性质和范围，但通过高分辨率超声可以轻松快速地评估该区域可触及动脉瘤的性质，是血管性还是非血管性。
