Prospective observational study on infecitious adverse events in patients with central venous catheter and port system. - Prospective observational study on infection of CV ports.

Fifty-nine patients were enrolled in this study and 60 central venous ports (CVPs) were implanted. Thirty-six (61%) patients had head and neck malignancies. Access route was subclavian vein in 43 (71.7%) CVPs and forearm vein in 17 (28.3%). CVP-related infection was observed in three (5.1%) patients: port-pocket infection in one and probable CVP-related infection in two patients, respectively. No definitive CVP-related blood-stream infection was observed. Before the placement of CVP, colonization at the insertion site was observed in 10 subclavian CVP patients while no colonization was observed in the forearm CVP patients. At 1 and 4 weeks, detection rates of colonization were also higher in subclavian CVP patients. No definitive relationship was demonstrated between skin colonization and clinical development of CVP-related infection.
