A Vascath dialysis line was inserted under direct ultrasound guidance into the left internal jugular vein for plasmapharesis to treat a 60-year-old woman admitted with a myasthenic crisis secondary to sepsis. A chest X-ray was arranged to check the position of the line and look for any complications, which revealed the presence of a left superior vena cava. Because of the uncertainty of the drainage of this vein a right-sided catheter was then inserted. The repeat chest X-ray (Figure 1) shows both lines, and the two vena cava.
在直接超声引导下，将一根Vascath透析导管插入左颈内静脉，用于进行血浆置换，以治疗一名因败血症继发重症肌无力危象而入院的60岁女性。安排了胸部X光检查导管位置并查找任何并发症，结果显示存在左上腔静脉。由于该静脉引流情况不确定，随后插入了一根右侧导管。复查胸部X光片（图1）显示了两根导管以及两条腔静脉。
