Manufacturer Narrative
Please note that this age is the average age of the parkinson's disease patients reported in the article; please note that this is the gender of the majority of parkinson's disease patients reported in the article ; please note that this date is based off the date of publication of the article as the actual event date was not provided.Other relevant device(s) are: product id: neu_unknown_lead, serial/lot #: unknown; product id: neu_unknown_ext, serial/lot #: unknown; product id: neu_ins_stimulator, serial/lot #: unknown.The reported events were from the following literature article: levi v, messina g, franzini a, di laurenzio ne, franzini a, tringali g, rizzi m.Antibiotics impregnated catheter coating technique for deep brain stimulation hardware infection: an effective method to avoid intracranial lead removal.Operative neurosurgery 0:1-8(2019).Doi: 10.1093/ons.Opz118.If information is provided in the future, a supplemental report will be issued.
 
Event Description
The following events were reported in literature: one (b)(6) year-old male patient with bilateral subthalamic nucleus (stn) deep brain stimulation (dbs) for parkinson¿s disease (pd) experienced a type ii infection of the right implantable neurostimulator (ins) 180 days after ins replacement.It was unclear if there was skin erosion and subcutaneous tissue involvement.After performing a brain computed tomography with contrast enhancement to rule out brain or meninges involvement, a superficial swab was obtained, and the patient was immediately started on ceftriaxone 2g iv q 12h and vancomycin 15 mg/kg q 12h for two weeks.Antibiotic treatment was then modified according to the results of the microbiological culture.Microbial cultures were negative.Due to the non-response to antibiotic therapy, incision, drainage, and hardware exploration was performed.The right ins and cable were removed 15 days later, with an attempt to spare the intracranial lead.The distal end of the lead was enveloped with a short segment (approximately 4cm long) of antibiotic-impregnated ventricular catheter containing clindamycin and rifampin.Sutures were used to close off the proximal end of the catheter in order to anchor it to the lead.After hardware removal, antibiotic treatment was continued intravenously for another two weeks.At the six-month follow-up, the patient underwent successful reimplantation of the extension and ins, which were connected to the salvaged lead.No further infective or hardware-related complications were noticed during the long-term follow-up.One (b)(6) year-old male patient with bilateral subthalamic nucleus (stn) deep brain stimulation (dbs) for parkinson¿s disease (pd) experienced a type ii infection of the left lead-cable junction 180 days after implantable neurostimulator (ins) replacement.After performing a brain computed tomography with contrast enhancement to rule out brain or meninges involvement, a superficial swab was obtained, and the patient was immediately started on ceftriaxone 2g iv q 12h and vancomycin 15 mg/kg q 12h for two weeks.Antibiotic treatment was then modified according to the results of the microbiological culture.Microbial cultures found coagulase-negative staphylococci (cons).Due to the non-response to antibiotic therapy, incision, drainage, and hardware exploration was performed.The left ins and cable were removed 16 days later, with an attempt to spare the intracranial lead.The distal end of the lead was enveloped with a short segment (approximately 4cm long) of antibiotic-impregnated ventricular catheter containing clindamycin and rifampin.Sutures were used to close off the proximal end of the catheter in order to anchor it to the lead.After hardware removal, antibiotic treatment was continued intravenously for another two weeks.At the six-month follow-up, the patient underwent successful reimplant ation of the extension and ins, which were connected to the salvaged lead.No further infective or hardware-related complications were noticed during the long-term follow-up.One (b)(6) year-old male patient with bilateral subthalamic nucleus (stn) deep brain stimulation (dbs) for parkinson¿s disease (pd) experienced a type ii infection of the right lead-cable unction 210 days after ins replacement.After performing a brain computed tomography with contrast enhancement to rule out brain or meninges involvement, a superficial swab was obtained, and the patient was immediately started on ceftriaxone 2g iv q 12h and vancomycin 15 mg/kg q 12h for two weeks.Antibiotic treatment was then modified according to the results of the microbiological culture.Microbial cultures were negative.Due to the non-response to antibiotic therapy, incision, drainage, and hardware exploration was performed.The right ins and cable were removed 15 days later, with an attempt to spare the intracranial lead.The distal end of the lead was enveloped with a short segment (approximately 4cm long) of antibiotic-impregnated ventricular catheter containing clindamycin and rifampin.Sutures were used to close off the proximal end of the cathete r in order to anchor it to the lead.After hardware removal, antibiotic treatment was continued intravenously for another two weeks.A dehiscence of the antibiotic catheter was noticed after two months; therefore, all hardware was removed.It was noted that this was initially conservatively managed by the patient¿s general practitioner with two weeks of oral antibiotics.One (b)(6) year-old female patient with bilateral subthalamic nucleus (stn) deep brain stimulation (dbs) for parkinson¿s disease (pd) experienced a type ii infection of the left implantable neurostimulator (ins) 240 days after lead placement.After performing a brain computed tomography with contrast enhancement to rule out brain or meninges involvement, a superficial swab was obtained, and the patient was immediately started on ceftriaxone 2g iv q 12h and vancomycin 15 mg/kg q 12h for two weeks.Antibiotic treatment was then modified according to the results of the microbiological culture.Microbial cultures showed (b)(6).Due to the non-response to antibiotic therapy, incision, drainage, and hardware exploration was performed.The left ins and cable were removed 17 days later, with an attempt to spare the intracranial lead.The distal end of the lead was enveloped with a short segment (approximately 4cm long) of antibiotic-impregnated ventricular catheter containing clindamycin and rifampin.Sutures were used to close off the proximal end of the catheter in order to anchor it to the lead.After hardware removal, antibiotic treatment was continued intravenously for another two weeks.At the six-month follow-up, the patient
