Retained port connectors after central venous port removal

We report three cases where the connector/sleeve, which helps fix the flexible catheter section to a port injection chamber, was inadvertently left in scar tissue during port removal. Concerned patients presented months later with a palpable subcutaneous nodule, near the port site. The nodules were variably imaged with plain X-rays, mammography or ultrasound with the diagnosis correctly made by a surgeon familiar with devices. Two connectors were removed, and one was left in place following discussions with the patient. Prevention, recognition and management of this problem are discussed.
