Device history record: the batch record, number 36982260 was reviewed: the batch is within the specifications and no discrepancy was observed.No other similar complaint was reported on the units released in august 2021.Summary of investigation: the device was implanted for 1 year.One celsite babyport set pur device, from batch 36982260, was returned for investigation.- visual inspection of the returned device: -> access port housing: some blood traces are observed.Around 5 puncture marks are detected inside the silicone septum.No defect is visually present.-> connection ring: the connection ring is still thread on the catheter and connected to the access port housing.No visible defects are detected.-> catheter: some coagulated blood is present inside the catheter.The catheter, of around 9.5 cm long, is still connected to the access port housing.4 longitudinal diametrically opposite cracks, between 2 to 7 mm long, are detected at the graduation level 5.In this area the catheter is also flattened.This proves that the catheter was pinched at this level, leading to these cracks.- dimensional measures: the inner and outer diameters of the returned catheter are measured and are compliant with the defined specifications.- x-ray picture review: the date of the x-ray picture is not visible, so it was impossible to determine whether it was the x-ray taken during device implantation or not.The catheter, of around 10 cm long, is implanted via the subclavian route onto a 3-year-old patient.Root cause: base on the observation performed on the returned catheter and on the x-ray picture, the root cause is confirmed: the catheter was crushed in the costo-clavicular space and repeated squeezing has led to the cracks of the catheter: it is the pinch-off syndrome.Conclusion: the complaint is not confirmed.Indeed, the cracks of the catheter was due to the fact that the catheter was crushed in the costo-clavicular space and repeated squeezing has led to the rupture of the catheter.This is the pinch-off syndrome.The instructions for use warn the physicians against the risk entailed by placing via the subclavian route.The incident is not imputable to the device; no actions plan is foreseen at that time.
