The frequency of arterial trauma or hematoma can be reduced by using smaller puncturing needles (21-gauge) and catheters (4- or 5- French). Versatile ultrafine guide wires are now available for selective and superselective catheterization. This miniaturization of angiographic equipment allows many vascular procedures to be performed safely on an outpatient basis or in short procedure units.
使用较细的穿刺针(21号)和导管(4或5法式)可降低动脉损伤或血肿的发生率。现在有通用的超细导丝可用于选择性和超选择性导管插入术。血管造影设备的这种小型化使得许多血管手术能够在门诊或短程手术单元中安全地进行。
