Abstract
Can long-term subcutaneous venous (Mediport) catheters be safely inserted without routine chest X-ray (CXR) verification? An estimated 500,000 Mediport catheters are inserted yearly in the United States, and elimination of unnecessary radiographs would result in substantial savings of increasingly limited health care resources. A total of 513 consecutive Mediport catheters were inserted by a single surgeon over a 5-year period using a standardized protocol and selective indications for follow-up CXR that included unilateral chest pain, aspiration of air, decreased breath sounds, and difficult catheter insertion. The 513 catheters were inserted in 498 patients with 271 patients (53%) undergoing postprocedure CXR. Of the 513 catheters 461 (90%) were placed by percutaneous approach to the subclavian vein. Six pneumothoraces (1.2% incidence) occurred, all in patients who met criteria for immediate CXR. The overall complication rate was 3.1 per cent and included eight instances of catheter-tip malposition (seven of the eight were successfully repositioned by vascular radiology), one mediastinal hematoma, and one chest-wall hematoma. This largest single-surgeon-reported series demonstrates that Mediport insertion can be safely accomplished with minimal complications following a standardized protocol using selective radiologic evaluation.
