Percutaneous placement of large-diameter dialysis catheters via the Seldinger technique can be technically challenging in patients with coagulopathy, difficult anatomy, or several previous central line insertions. We describe a method for achieving safer access by combining an open approach to delineate the venous anatomy of the chest wall, with a micropuncture device and smaller diameter guidewire to gain intravascular access to the cephalic vein or its major tributaries. Serial dilation of otherwise unusable vessels can then permit successful and safer hemodialysis catheter insertion in these difficult cases.
对于患有凝血病、解剖结构复杂或先前多次进行中心静脉置管的患者,通过Seldinger技术经皮放置大口径透析导管在技术上可能具有挑战性。我们描述了一种方法,即通过开放入路来描绘胸壁静脉解剖结构,并结合使用微穿刺装置和较小直径的导丝来获得头静脉或其主要分支的血管内通路,以实现更安全的血管穿刺。然后,对原本无法使用的血管进行逐级扩张,从而在这些困难病例中成功且更安全地插入血液透析导管。
