Spontaneous Catheter Migration of Implantable Vascular Access Device-Two Case Reports and Review of the Literature

植入式血管裝置，有時被稱為“植入式注射座”，通常用於抽取血液樣本、給藥、輸液及營養的補充。有些併發症會導致此裝置功能不彰，我們描述了兩個少見的例子乃有關植入式血管裝置之導管的自動漂移。在第一個病例中，植入座的功能不佳並且注射時常常無法全速開啟，最後導致完全阻塞。在第二個病例中，植入座功能不佳且導管持續漂移。中央靜脈導管的漂移可以導致血管、神經、或感染等併發症，雖然有些作者報告可用非手術的方式矯正移位元的中央靜脈導管，但很難將相同的方式應用於植入式注射座，因為這種裝置是完全埋於皮下的，在這種病例中，拔除原裝置及重新裝設通常是必需的。

The implantable vascular access device (IVAD), sometimes called the ”implantable infusion port”, is usually used for drawing blood samples, administering drugs, and supplying fluids or nutrition. Some of the complications that cause malfunctioning of the device have been reported. We describe herein two unusual cases with a spontaneous catheter migration of the IVAD. In the first case, the initial port malfunctioning was followed by a total occlusion and an inability to infuse. In the second case, the port malfunctioned, and only sometimes was not in a full-running mode during infusion. A migration of the central venous catheter can lead to vascular, neurologic, or infectious complications. Although some authors have reported non-operative methods to correct the positioning of the displaced central venous catheter, it is difficult to re-position the catheter of an IVAD, which is implanted completely subcutaneously. Removal and replacement are usually necessary in these cases.
