摘要： 口腔颌面恶性肿瘤术前诱导化疗时，常规行经外周静脉中心静脉置管（Perpherally inserted cerctral Denous cathetere, PICC）。在PICC置管正确，完成术前诱导化疗后，出现PICC管异位的情况罕见。本文报道1例舌癌术前诱导化疗后，术中发现PICC管异位于术侧颈内静脉内，经妥善处理后将其取出。

Abstract: Induction chemotherapy before oral and maxillofacial ablative surgery is often treated with PICC catheter. On the premise of correct placement of PICC catheter, it is rare to see the malposition after preoperative induction chemotherapy. This article reported a 61-year-old male with tongue cancer staged at T2N2aM0. During neck dissection, the PICC catheter was found misplaced in jugular vein. This malposition occured after preoperative induction chemotherapy. After proper treatment, it was completely removed.

Key words: jugular vein, PICC, ectopic, radical neck dissection
