A case of spontaneous fracture of the outlet catheter of a totally implanted catheter system (Port-A-Cath) is presented. The outlet catheter was fractured at the entrance into the left subclavian vein twenty-one weeks after insertion and the distal part was embolized in the right ventricle. The embolized catheter fragment was retrieved by a 'goose-neck' snare via the right femoral vein. The awareness of a possible spontaneous fracture of the outlet catheter of a totally implanted catheter system (Port-A-Cath) is important to prevent accidental spillage of potent cytotoxic substances.
本文报告一例完全植入式导管系统（Port-A-Cath）出口导管自发性断裂的病例。出口导管在植入后21周于左锁骨下静脉入口处断裂，远端部分栓塞于右心室。通过“鹅颈”圈套器经右股静脉取出栓塞的导管碎片。认识到完全植入式导管系统（Port-A-Cath）出口导管可能发生自发性断裂对于防止强效细胞毒性物质意外溢出很重要。
