Peripherally inserted central catheter (PICC) migration into azygos vein (AV) is a rare complication. It is recognised only when catheter malfunction occurs or when patients develop associated complications. PICC migration into AV has been reported to be associated with various complications such as catheter malfunction, perforation, haemorrhage, thrombosis, infection and stenosis of AV. Pleural effusion and trachea-azygos fistulas have also been reported. We present a patient with recurrent migration of PICC into AV after an initial corrective repositioning during the same hospital stay. In this case, PICC migration was possibly related to left-sided approach, use of smaller diameter PICC, severe congestive heart failure and her bedbound status. PICC migration should be considered when PICC found be malfunctioning, especially if associated with the above risk factors.
外周静脉穿刺中心静脉导管（PICC）移入奇静脉（AV）是一种罕见的并发症。只有当导管出现故障或患者出现相关并发症时才会被发现。据报道，PICC移入AV与各种并发症有关，如导管故障、穿孔、出血、血栓形成、感染以及AV狭窄。也有报道出现胸腔积液和气管-奇静脉瘘。我们报告一例患者，在同一住院期间首次进行纠正性重新定位后，PICC反复移入AV。在这种情况下，PICC移位可能与左侧入路、使用较小直径的PICC、严重充血性心力衰竭及其卧床状态有关。当发现PICC出现故障时，尤其是伴有上述危险因素时，应考虑PICC移位的情况。
