title: Case report: the malfunctioning implanted venous access device.
abstract: Totally implanted venous access devices (VADs) are an alternative to central line placement for those patients requiring frequent intravenous access. Venous thrombosis, infection, extrusion, extravasation and occlusion are commonly encountered complications of central VADS. Fracture with embolization of implantable venous access catheter is a rare complication of this commonly used device, but it may have serious consequences. Clinical manifestation may include infraclavicular or chest pain, paraesthesias in the arm, cardiac arrhythmias, palpitation or an extra heart sound, in addition to withdrawal occlusion, swelling, and resistance to infusion. Nursing staff should be aware of these signs and symptoms and they should immediately stop any infusion if these signs and symptoms emerge. Whenever problems with a VAD occur a chest radiograph or a contrast enhanced angiographic control of the VAD is advised. This article provides two cases relating to malfunction of a VAD. Despite typical symptoms in both cases a catheter fracture with embolization was not taken into consideration, and a radiological control of the VAD was not performed. It was only by chance that the patients did not sustain any harmful sequels from the broken VAD.
