To determine the frequency of arm port catheter fracture and embolization related to the Cook Vital Port Mini Titanium.
A retrospective audit of our Cerner Radiology Information System was performed between June 1, 2006, and June 30, 2011, to determine the number of Cook arm venous ports implanted and the frequency of foreign body retrievals related to catheter fracture for these arm ports.
A total of 691 arm implantations of the Cook Vital Port during the 5-year time frame were analysed. Eleven of these patients (1.6%) required intravenous foreign body retrieval in the interventional radiology suite related to catheter fracture and embolization. Three of these fractured catheters were retrieved from the peripheral venous system upstream of the pulmonary circulation, whereas 8 embolized to the pulmonary arteries. All were successfully extracted with an intravenous snare by interventional radiology.
We discovered a 1.6% frequency of catheter fracture and embolization associated with arm implantation of the Cook Vital Port. All the catheters fractured at the vein entry site and did not detach from the port housing. The cause for catheter fracture and embolization is uncertain. Pulmonary embolization of the fractured catheters puts the patients at risk for possible further complications. No patients had ancillary complications related to catheter embolization or to catheter extraction procedures. Further investigation is required in an attempt to determine the circumstances that may result in catheter fracture and embolization related to this venous access device.
确定与 Cook Vital Port Mini Titanium 相关的臂部端口导管断裂和栓塞的频率。
对我们的 Cerner 放射信息系统进行回顾性审核，时间范围为 2006 年 6 月 1 日至 2011 年 6 月 30 日，以确定 Cook 臂部静脉端口的植入数量以及与这些臂部端口相关的导管断裂导致的异物取出的频率。
在 5 年的时间内，共分析了 691 例 Cook Vital Port 臂部植入。其中 11 例（1.6%）患者需要在介入放射学室进行静脉内异物取出，与导管断裂和栓塞有关。其中 3 例断裂导管在肺循环上游的外周静脉系统中取出，8 例栓塞至肺动脉。所有病例均通过介入放射学成功地用静脉内圈套器取出。
我们发现，与 Cook Vital Port 臂部植入相关的导管断裂和栓塞的频率为 1.6%。所有导管均在静脉入口处断裂，未从端口外壳上脱落。导管断裂和栓塞的原因尚不确定。断裂导管的肺栓塞使患者面临可能进一步发生并发症的风险。没有患者因导管栓塞或导管取出过程出现其他并发症。需要进一步调查，以确定可能导致与这种静脉接入装置相关的导管断裂和栓塞的情况。
