Incidence and outcome of retained Port-A-Cath fragments during removal

Abstract

Purpose

Port-A-Cath devices are frequently used for long-term venous access. We postulate that long-term use predisposes them to getting stuck and retained in a central vein at the time of removal. We aim to report the incidence and outcome of this complication.

Methods

Between January 2006 and July 2016, a retrospective review of all Port-A-Cath removals that were performed at our centre was conducted. At the time of removal, catheters that could not be removed from the vein were considered retained.

Results

During the study period, 107 children had 174 episodes of silicone Sitimplant (Vygon, Ecouen, France) Port-A-Cath insertions. These children required 135 removal episodes and there were 3 (2.2%) instances whereby the catheter fragment was retained. These episodes of retained catheters only occurred in children with factor VIII deficiency (4.1% incidence in this cohort). For each episode of catheter insertion and removal, the catheters had been left in situ for a mean duration of 43 months in children with factor deficiency and no retained fragments, and the mean duration was 91 months in children with factor deficiency and retained catheter fragments (p = 0.0011).

Conclusions

Port-A-Caths that are retained after attempted removal is a complication encountered predominantly in catheters that have been in use for a prolonged duration. Furthermore, factor replacement therapy in haemophiliacs may be a risk factor for this complication.
