Portacath implantation with introduction of a catheter into the superior vena caval system is a commonly performed procedure. Catheterization of the internal jugular vein can be difficult due to anatomical variation, individual patient morphology, or as a result of previous catheterization. Use of 2D ultrasonography facilitates localization of the internal jugular vein and decreases the risks of catheter placement.
将导管引入上腔静脉系统的输液港植入术是一种常见的操作。由于解剖变异、个体患者形态或既往插管的原因，颈内静脉插管可能会很困难。使用二维超声有助于颈内静脉的定位，并降低导管放置的风险。
