An unusual placement of a "central" venous catheter in the porto-hemiazygous system of a cirrhotic patient in septic shock is described. The catheter was misinterpreted as being located in a central vein and served initially as a guide for volume replacement. The high central venous pressure recorded (22 cm H2O) in spite of signs of hypovolemia led to the introduction of a Swan-Ganz catheter which confirmed the presence of hypovolemia. The proper position of the central venous catheter, especially in cirrhotic patients, should not only be confirmed by plain chest x-ray but also by injection of contrast medium.
描述了一名感染性休克肝硬化患者的“中心”静脉导管在门静脉-半奇静脉系统中的异常放置情况。该导管被误判为位于中心静脉，并最初用作容量补充的引导。尽管存在低血容量迹象，但记录的中心静脉压较高（22 cm H2O），这促使插入了一根Swan-Ganz导管，该导管证实了低血容量的存在。中心静脉导管的正确位置，尤其是在肝硬化患者中，不仅应通过胸部平片确认，还应通过注射造影剂来确认。
