Polyurethane versus silicone port a cath: What's going on at removal?

Background

Port-a-cath (PAC) is an essential device in the management of the patients of chronic illness, but despite theirs benefits there are many complications either at the time of insertion or at time of removal. Our aim of this study is to evaluate the fracture rate of the catheter at removal time in comparison with catheter type either polyurethane or silicone.

Methods

A retrospective monocentric study of all PACs which were removed at our university pediatric hospital between 1 January 2006 and 31 December 2016. Two groups were compared: polyurethane group and silicone group.

Results

Total of 216 central lines were removed, the mean age at the time of extraction was 9.7 ± 4.9 years and the mean time for both catheter was 2.7 ± 1.6 years, fracture occurred in 11 catheter of the polyurethane group (n = 119), with no fracture of silicone group (n = 86), in the polyurethane group, the risk of catheter fracture is significantly related to the duration of the PAC in place.

Conclusion

We found that the polyurethane-based catheters are more vulnerable for rupture and retained fragment in the blood vessels, especially if left in place for long time, for this reason we have switched to silicone-based catheter and all catheters should be remove within duration maximal of 2 years.

Type of study

Prognosis study.

Level of evidence

Level II.
