We report on a 66-years-old oncological patient with a spontaneous dislocation of a portcatheter into the pulmonary artery. The catheter fragment had a loop formation, both ends were located in the proximal right segment arteries. The first attempt of a removal of the catheter via the right heart into the inferior caval vein by means of a hooked pulmonalis-catheter failed. In a second manoeuvre, the catheter fragment was successfully fixed by means of a catheter with an extendable loop configuration (goose-neck) and retrieved from the pulmonal artery into the inferior caval vein. Then, the entire system could be removed together with the introducer sheet under mild traction from the femoral vein without any complications. In conclusion, the percutaneous interventional method appears to be a minimally-invasive approach to deal with catheter fragments dislocated in the central veins and the pulmonary arteries.
我们报告了一例66岁的肿瘤患者,其输液港导管自发脱位至肺动脉。导管碎片形成一个环,两端位于右肺上叶前段动脉。首次尝试通过带钩的肺动脉导管经右心将导管送入下腔静脉,但未成功。在第二次操作中,使用可伸展环形结构(鹅颈形)的导管成功固定导管碎片,并将其从肺动脉取出至下腔静脉。然后,在轻微牵引下,可将整个系统连同导入鞘一起从股静脉取出,无任何并发症。总之,经皮介入方法似乎是处理脱位至中心静脉和肺动脉的导管碎片的一种微创方法。
