Long-term outcomes of radiologically placed arm ports.

Abstract

To evaluate long-term outcomes of an initial experience with radiologic placement of arm ports. The follow-up of 46 consecutive arm port placements (44 patients) was reviewed by means of chart review (hospital, office, and clinic) in 41 patients, telephone interview in 20, physical, examination in 15, and venous ultrasound in 14. Data on port complications and function were recorded. Statistical methods were the Fisher Exact Test and Cochran-Mantel-Haenszel Test. Technical success for placement was 100%. Follow-up was obtained in 41 (93%) of the 44 patients (43 ports); mean days of catheter use was 344 days (total, 14,797 days; range, 10-1,104 days; median, 278 days). Rate (per 100 catheter days) of symptomatic central venous thrombosis was 0.054; arm phlebitis, 0.007; confirmed infection, 0.034; and catheter dysfunction, 0.095. Prophylactic anti-coagulants did not affect symptomatic central venous thrombosis (P > .05, Fisher Exact Test). Catheter tip high in the right atrium was marginally associated with better catheter function (P = .041, Fischer Exact Test). Good long-term results can be anticipated with radiologic placement of arm ports.
