Herein we report a case of cardiac tamponade secondary to perforation of the superior vena cava by a central venous catheter in an obstetric patient. 我们在此报告一位产科病患进行中央静脉导管术，因上腔静脉穿刺破裂导致心包膜填塞。
The unexpected focal activity in the central venous catheter was more likely due to the accumulation of FDG in the catheter. 此不预期之局部活性最有可能是因为气化去氟葡萄糖累积于中央静脉导管。
