This paper presents our experience with two-dimensional echocardiography in the detection of 61 intravascular catheters or wires in a series of 39 infants and children. It was possible to identify intravascular wires as small as 0.5 mm in diameter and intravascular catheters as small as 0.9 mm in diameter. In no instance, was an intravascular catheter not detected. The two-dimensional echocardiogram is demonstrated to be a tool to assist the physician in placement of intravascular catheters. In the catheterization laboratory, the two-dimensional echocardiogram is useful in determining catheter location, particularly in the presence of complex congenital defects. Two-dimensional echocardiographic guidance of catheters minimizes exposure to ionizing radiation.
本文介绍了我们利用二维超声心动图检测39例婴幼儿血管内61根导管或导丝的经验。能够识别直径小至0.5毫米的血管内导丝以及直径小至0.9毫米的血管内导管。无一例血管内导管未被检测到。二维超声心动图被证明是协助医生放置血管内导管的一种工具。在导管插入实验室，二维超声心动图有助于确定导管位置，尤其是在存在复杂先天性缺陷的情况下。导管的二维超声心动图引导可将电离辐射暴露降至最低。
