Abstract
|
|
|
Totally implanted central venous access devices for chemotherapy (chemoport) are being used increasingly in lung
cancer patients. Vascular catheters are associated with various complications including infection, thrombosis as
well as spontaneous fractures and embolization of the catheter, which is known as ’pinch-off syndrome’. ’Pinch-off
syndrome’ refers to the compression of a subclavian central venous catheter between the clavicle and first rib
resulting in an intermittent or permanent obstruction, which can lead to tears, transection, or embolization. We
report two cases of fractured and embolized implanted subclavian venous catheters in which the fragments were
removed percutaneously. A 62-year-old man presented with back pain with a duration of a few weeks. The chest
radiograph revealed complete transsection and embolization of the catheter into the right atrium. In addition, a
47-year-old woman with a chemoport had a grade 3 pinch-off sign in a chest radiograph demonstrating complete
transsection and embolization of the catheter into the pulmonary artery. Both cases were managed by retrieving
the embolized distal fragment percutaneously and removing the proximal section of the catheter.
