Persistent left superior vena cava catheterization for venous port is still sporadically reported, let alone combined with variations of the azygos.
During the implantation of a venous access port in a 73-year-old patient, who was planned to carry out postoperative chemotherapy, a persistent left superior vena cava was discovered. A review of the preoperative plain chest computed tomography further corroborated the existence of a double superior vena cavas. Besides, the right azygos vein was absent and a left azygos vein draining into the persistent left superior vena cava was evident. The diameter of the persistent left superior vena cava was greater than that of the right SVC. Consequently, the decision was made to insert the catheter into the persistent left superior vena cava for the subsequent implantation procedures. The surgery was successful and no complications related to the venous port occurred during the whole catheter days.
The rare persistent left superior vena cava with variant azygos vein should not be a contraindication for venous port implantation after a comprehensive evaluation.

静脉输液港行永存左上腔静脉置管仍有零星报道，更不用说合并奇静脉变异的情况了。
在为一名计划进行术后化疗的73岁患者植入静脉输液港时，发现了永存左上腔静脉。术前胸部平扫计算机断层扫描进一步证实存在双上腔静脉。此外，右侧奇静脉缺如，可见左侧奇静脉汇入永存左上腔静脉。永存左上腔静脉的直径大于右侧上腔静脉。因此，决定在后续植入过程中将导管插入永存左上腔静脉。手术成功，在整个置管期间未发生与静脉输液港相关的并发症。
经过全面评估，罕见的永存左上腔静脉合并奇静脉变异不应成为静脉输液港植入的禁忌证。
