Summary

A rare silastic dural substitute complication occurred 32 years post-implantation, a record latency period. This case highlights the risk of late infections and hemorrhages from silastic dural implants, emphasizing the need for increased awareness.

Background:

A silastic dural substitute complication is presented, occurring after a 32-year latency period, the longest documented.
This case involves a patient who received a silastic duraplasty following a traumatic brain injury.

Observation:

A patient developed memory problems and dysphasia 32 years after a silastic duraplasty.
Imaging revealed an expanding hemorrhagic mass around the dural implant.
Cultures identified Acinetobacter spp. in the cerebrospinal fluid.

Findings:

Surgical removal of the silastic implant and hemorrhagic mass was performed.
The patient experienced a slow improvement but with lasting cognitive deficits.
This represents the longest reported latency period for such a complication.

Implications:

This case extends the known latency period for silastic dural substitute complications by 60%.
Increased awareness of late-onset infections and hemorrhages from these implants is crucial for timely diagnosis and treatment.
Neurosurgeons should consider the potential for delayed complications even decades after implantation.
