Event Description

Mfr received pa and lateral chest and left neck x-rays from the treating physician to review the integrity of the lead. The physicians notes regarding the x-rays stated that there was no lead breaks observed and the sys appeared intact. Review of x-rays by the mfr revealed no obvious lead discontinuities or anomalies. The lead pin was fully inserted in to the generator, but was not able to be visualized past the connector block. Further follow up with the treating physician revealed that the pt had surgery recently to remove cysts on the posterior neck region, and that the pt has lennox-gastaut syndrome, static encephalopathy, and medically intractable epilepsy. Additionally, it was noted at a recent follow up visit, a sys diagnostic test revealed high lead impedance. Attempts to obtain add'l info from the treating physician are underway. Revision surgery is likely.
