Magnetic resonance imaging (MRI) is contraindicated with an indwelling lead. Lead migration is another complication that should be considered with device failure. This minimally invasive surgical procedure is subject to complications, … Treatment of infections of the extraneural tissues can be with oral or intravenous antibiotics if the problem is superficial. Epidural insertion in anesthetized adults: Will your patients thank you? Spinal cord stimulators are devices that produce a low voltage electrical signal that is thought to disrupt the pain pathway between the spine and … In a landmark study, Kemler reported an 11% incidence of postdural puncture headache [18]. In the 1700s, several great minds worked on the concept of capturing electricity to be used to help the suffering. They also must be psychologically stable, and if they suffer from comorbid depression, anxiety disorder, drug addiction, systemic infections, or bleeding disorders, these conditions must be successfully managed before proceeding [7]. Open incision and drainage is a treatment option if the seroma does not resolve. The following are some of the complications that may occur during or after spinal cord stimulator procedures. HHS 2015 Oct;39(4):E15. Both patients underwent reoperation. This 61-year-old … When the lesion compresses the spinal cord or nerves, serious deficits can occur which may progress to paraplegia. The process of implanting and caring for a patient with a SCS system is complicated. Minor complications were reported in six patients (8.82%) and included wound dehiscence, infection, and prolonged ileus in one case. However, the sedated patient does not identify nerve root pain to warn of impending difficulties, increasing the risk of complications due to injury to neural tissues. This technique is indicated in patients with moderate to severe pain of the limbs or trunk that has failed more conservative approaches. In most cases, a high fever is present and in many other cases it is in excess of 38.3°C. Neurosurg Focus. When additional reinforcement of the wound is needed, a skin closure with stainless steel staples or nonabsorbable sutures such as nylon is recommended. Incision and drainage may be required if the generator or leads are involved, and removal of the device may be required. Electrical current has been used to treat disease for thousands of years. The highest risk for bleeding is in the first 24 hours. Prior to moving forward with the scheduling and performance of the system, the physician should discuss the risks related to the needle and lead in the immediate procedural period, as distinct from the separate risks involved with making incisions, anchoring, and tunneling. Jeon SY, Ji JY, Yoo SH, Chon JY, Jung SH, Moon HS. The therapy was first reported four decades ago, and has improved in many areas including technical equipment, patient selection, and physician training. A recent panel of experts discussed this issue in depth when considering the need for standard MRI prior to implanting a lead. Due to the inherent difficulty of identifying complications by peer review and closed claim analysis, the incidence of complications with SCS is unknown. 1). Conclusion: A hematoma can occur at the generator site from an acute arterial bleed or a slow venous leak. Spinal cord and peripheral nerve stimulation therapies are safe and reversible therapies. Anesthesia options for SCS vary from local anesthesia to general anesthetics. Iota-carrageenan neutralizes SARS-CoV-2 and inhibits viral replication in vitro. Wound closure can best be achieved with an absorbable suture in the deeper tissues and also in the subcuticular layers. When the staples or sutures are removed, the wound should remain dry for approximately 24 hours to allow the holes and tracts left by the closure to seal. J Anesth. On average, patients who developed complications lost 20 mL more blood during surgery than those who did not develop complications (p = 0.006). Chronic pain is long standing pain that persists beyond the usual recovery period or that accompanies a chronic health condition. Biologic complications commonly occur within 3 months of implant, although infections can rarely present much later. If the aforementioned treatments are unsuccessful, the use of a blood patch has been reported to be helpful [19]. Most patients who undergo SCS implantation are satisfied with the results. When turned on, the SCS stimulates the nerves in the area where … The issue of fibrosis may be less critical in the future as systems allow for more extensive coverage of the spine and nerve fibers. Techniques that increase the risk of dural puncture include midline approach, angle of entry greater than 60°, and use of the retrograde approach. The patient should understand that the risk of the trial revolves around the lead, needle, and anesthesia. The technique involved with the placement of these implants requires the placement of a programmable lead into the epidural space by either a percutaneous needle approach or an open surgical approach [5]. Spinal cord stimulation (SCS) has been shown to be a safe, effective, and drug-free treatment option for many chronic pain conditions including refractory low back pain. An MRI was recommended in the cervical spine if the patient had a history of cervical spine disease (Levy R., personal communications, November 10, 2006). He reported that in his experience, the relief provided was often overridden by complications including skin burns and pain with increasing current and voltage. Further work revealed that electricity is involved in muscle movement, neurological function, and pain perception. In some settings, the amount of fibrosis does not appear to cause any change in the patient's condition and does not require treatment [20]. Outcomes of percutaneous and paddle lead implantation for spinal cord stimulation: a comparative analysis of complications, reoperation rates, and health-care costs. When using local anesthetics with epinephrine, the risk of acute bleeding is reduced because of vasoconstriction, but the risk of subacute bleeding is increased because the epinephrine may lose its effect after wound closure. In some cases, an epidural hematoma can develop due to intrinsic clotting disorders, medications that effect clotting, or severe tears in the vessels. How much you can expect to pay out of pocket for spinal cord stimulation, including what people paid. The most disastrous complications that can arise during implantation of these devices involve the neuraxis. Other options include surgical lead revision, or revision to a more complicated system [25–27]. If the patient has had staples or sutures, removal could occur anywhere from 7 to 10 days depending on the general health of the patient, body habitus, and condition of the wound. Complications related to spinal cord stimulation may be technical or biologic. 2015 Jul;18(5):367-75. doi: 10.1111/ner.12239. 2013 Sep-Oct;16(5):418-26; discussion 426-7. doi: 10.1111/ner.12065. When an epidural hematoma is suspected, the radiologists, spine surgeon, and implanting doctor should work together to expedite the diagnosis and treatment of the problem. In these settings, the author recommends a surgical lead revision. A spinal-cord stimulator implant lawsuit is an option for patients injured as a result of electronic pain-management devices marketed by Abbot/St. I’m so scared of more surgeries […] In some facilities with a history of patients infected with resistant organisms such as methicillin-resistant Staphylococcus aureus, vancomycin is recommended as a first line agent. Painful stimulation may also occur with fibrosis causing current transfer to the lateral nerve roots and spinal structures. If a hematoma goes untreated, it can lead to wound dehiscence and wound infection with loss of the system. Side Effects of Spinal Cord Stimulator Here are some Spinal Cord Stimulator side effects generally experienced: The procedure may not work everyone. Neuromodulation. When epidural hematoma is confirmed, treatment is by surgical evacuation within 24 hours of the injury [14]. Spinal Cord Stimulator (SCS) Systems Boston Scientific’s Spinal Cord Stimulator (SCS) systems are designed to help treat chronic pain. Bleeding. Timothy R. Deer, MD, C. Douglas Stewart, PA/C, MBA, Complications of Spinal Cord Stimulation: Identification, Treatment, and Prevention, Pain Medicine, Volume 9, Issue suppl_1, May 2008, Pages S93–S101, https://doi.org/10.1111/j.1526-4637.2008.00444.x. In another analysis, Kumar found lead complication rates to be 5.3%, a low infection rate of 2.7%, and an epidural fibrosis rate of 19% [9]. However, it requires implantation of an electrode array and its associated power source. Jude, Boston Scientific Corp., Medtronic, Inc., or Nevro. Would you like email updates of new search results?

A close analysis is also made of clinical assessment and actions that are important in reducing or preventing these sometimes devastating events. This can produce a surgical level of anesthesia for pocketing and tunneling. When considering these possible complications, the patient and the physician should have a frank discussion on the relatively low risk of the trial and comparatively increased risks of placing the device permanently. (A) Pre-lead migration; (B) lead migration. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Postoperative complications occurred in eight patients (11.75%), two of which were classified as major (2.94%). Neuromodulation. Since the initial use of SCS by Shealy, the devices have changed from bipolar leads with an external power source to multi-contact leads with rechargeable generators. Hardware-related complications are more common than biological complications with lead-related complications most frequent. Electromyograms and nerve conduction studies may be helpful but may be normal for several weeks following injury [17]. Treatment is by surgical revision and by adding new technology to reduce the impact of future fractures. Treatment can be by pressure applied to the tissue, needle aspiration, or by surgical incision and drainage. Spinal cord stimulation is a therapy used for the relief of neuropathic pain of the trunk and limbs. We identified 68 patients during this interval who had a paddle electrode removed. 2016 Jan;19(1):85-90. doi: 10.1111/ner.12370. 2015 Dec;29(6):953-6. doi: 10.1007/s00540-015-2038-4. Disease states that may benefit from preoperative intercession include psychiatric disorders, diabetes mellitus, immunological diseases, disorders of the coagulation system, recent infectious diseases, and other hormonal disorders. However, removal is not without some risk though the overall risk of minor or major complication is low. Thin wires carry current from a pulse generator to the nerve fibers of the spinal cord. USA.gov. Pain at the generator site, lead site, or connectors, can lead to poor patient satisfaction. Percutaneous adjustment method for transversely migrated spinal cord stimulation leads: a technical report. Physical discomfort from the implanted stimulator and/or leads. The risk of infection can be reduced by careful prepping, draping, and gentle treatment of the tissues. In thin patients this may require moving the generator below the fascia or muscle belly. In some patients, particularly those with significant coexisting diseases, fever may not be present and no symptoms of infection may occur. Results: Table 2 shows the occurrence of these problems. Alo reported a much lower number of 6% [23]. © 2017 International Neuromodulation Society. Much like the history of electrical therapies for the treatment of disease, spinal cord stimulation (SCS) has seen a major evolution since it was first reported in the literature four decades ago. Epub 2015 Dec 8. If the problem does not resolve in a reasonable time, an incision and drainage must be performed [21] (See Figure 4). The consensus was that an MRI is not required of the thoracic spine prior to a lumbar thoracic implant. Cameron reported the following complication rates based on reviewed studies: 1) lead migration 13.2%; 2) lead breakage 9.1%; 3) infection 3.4%; 4) hardware malfunction 2.9%; and 5) unwanted stimulation 2.4% [24]. ... Spinal Cord Stimulation Prescription and Safety Information. If the patient has had a previous history of staphylococcal infection, a consultation with infectious disease may be warranted in the preoperative period. The wound should be closed in the usual fashion using either interrupted or running absorbable sutures and multiple layers to assure that all dead space is obliterated and there is no tension on the skin. You will not get 100% pain relief. The most common neurological insult from SCS is inadvertent dural puncture.  |  We retrospectively reviewed the outcomes of all patients at the Cleveland Clinic who underwent removal of SCS paddle electrodes between 2009 and 2016. The use of preoperative antibiotics is sometimes debated in regard to their utility or benefit. In rare cases, a burn of the skin can occur due to overheating. A sterile nonocclusive dressing is applied over the wound and should remain undisturbed for 48–72 hours if the dressings are not grossly soiled; at this point, if the wounds are dry and there is no seepage, the patient may shower without disturbing the wounds. If weakness develops, a vigilant search should occur for the cause of this problem. High pressure, high volume antibiotic irrigation should be considered at the time of surgical exploration, to dilute any possible contaminants in the tissue. Prophylactic removal is not recommended. Chronic pain may prevent people from working, eating properly, participating in physical activity or enjoying life. Device-related complications consist of lead migration, lead breakage, over or under stimulation, intermittent stimulation, hardware malfunction, loose connections, battery failure, … Please enable it to take advantage of the complete set of features! It is important to consult with an infectious disease practitioner prior to reimplant for advice on antibiotic coverage. Biological complications include commoner complications such as infection and pain over the … One of these patients developed a postoperative cerebrospinal fluid leak, and another suffered a large suprafascial hematoma. The patient and implanting doctor should also discuss the different methods of placing a permanent system through a percutaneous approach similar to the trial or the surgical lead approach which involves a more extensive surgical technique. We report a case of spinal cord injury (SCI) during SCS explant and revision. A spinal cord stimulator (SCS) device is surgically placed under your skin and sends a mild electric current to your spinal cord (Fig. If the problem does not resolve, surgical revision may be required. In regard to pain relief and neurological diseases, early reports were optimistic for the use of this treatment for headaches, joint pain, hysteria, and depression. Complications; electrode paddle; electrode removal; paddle removal; spinal cord stimulation. The patient should be prepped on each occasion over an area greater than 6 cm from the proposed surgical site with a solution found to be beneficial in the facility in which the procedure is being performed. Franzini A Ferroli P Marras C Broggi G. Torrens JK Stanley PJ Ragunathan PL Bush DJ. The physician should limit the use of electrocautery near the superficial tissues, near the dermis, should consider bipolar heating when possible, and should close in two to three layers to better approximate the tissue edges. It is critical to inspect the wound prior to closure for this problem. Epub 2015 Jun 21. The risks of the procedure are small compared with repeat back surgery, and outcomes may be more effective compared with other chronic pain therapies as measured by patient satisfaction and cost-effectiveness, [28–30]. Infection of the pocket or paraspinous electrodes can lead to the need for revision or removal of the system. During that time period, energy was harnessed in crude capacitors called Leyden jars. In rare cases, this may require explanting of the device. With specific nerve stimulation such as that with the retrograde or transforaminal approach, the presence of fibrosis may lead to the inability to program the system or even to perceive stimulation. If the physician chooses to aspirate the seroma, careful attention should be paid to sterile technique. Objective: Complications related to the use of spinal cord stimulation for managing persistent postoperative neuropathic pain after lumbar spinal surgery. The use of conscious sedation with monitoring is helpful to enable the patient to tolerate the procedure while also remaining conversant and alert to reduce the risk of neurological damage. A previous study submitted by stimulator manufacturers (Medtronic, Boston Scientific and St. Jude Medical) showed a rate of only 3.8 complications per 1,000 implants. Once the lead is in proper position, as determined by patient response or X-ray confirmation, a subcutaneous pocket is made and tunneling tool is used to place wires from the leads to a generator. Some of the reported complications from a spinal cord stimulator include: Device malfunctions; Shocks or burns; Infection; Spinal cord nerve damage; Muscle weakness; and Paraplegia. Epidural fibrosis can occur with an indwelling lead in place. The Incidence of Spinal Cord Injury in Implantation of Percutaneous and Paddle Electrodes for Spinal Cord Stimulation. The surgical areas should be patted dry and then redressed with a sterile nonocclusive dressing. COVID-19 is an emerging, rapidly evolving situation. The evolution of these therapies can be traced from Ancient Greeks using torpedo fish to treat arthritis and other disease states [1]. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Stimulation patterns should be monitored and reprogrammed as needed in the first 6 weeks after surgery. This may be caused by excessive tissue trauma, such as aggressive sharp dissection, excessive use of cautery, or forceful blunt retraction. Taylor had a device complication rate of 43%, which was elevated by the inclusion of minor issues such as pain at the pocket site [22]. The skin may be approximated with a subcuticular stitch, nylon, or staples. In the past few years, a new complication has developed due to recharging of generators. The use of general anesthesia or deep sedation appears to increase the risk of this type of complication [16]. When other pain treatments have failed, spinal cord stimulation may be an option. Babu R, Hazzard MA, Huang KT, Ugiliweneza B, Patil CG, Boakye M, Lad SP. When invading the epidural space with a needle or rigid lead, the chance exists to puncture a blood vessel. I had Stimwave spinal stimulator placed a year ago and nothing but problems and severe pain thinking of having it removed and possibly replaced with nevro hf10 . It should take between two to four weeks for complete healing, but as with all medical procedures this varies from patient to patient. NIH Telemetry and impedance testing can be done in the pocket prior to closure to assure the depth is not excessive. The diagnosis of meningitis requires cerebral spinal fluid analysis [15]. Intrauterine contraction parameters at baseline and following epidural and combined spinal-epidural analgesia: A repeated measures comparison. Chapter Synopsis: Electrical stimulation of the spinal cord (SCS) is generally a safe and effective treatment for neuropathic pain and other conditions. By careful attention to detail, the implanting doctor can reduce the incidence of bad outcomes, enhance the effectiveness of the procedure, and improve patient outcomes. At the time of the procedure, the patient should be assessed for skin disorders or infection at the site of the needle entry or incision.
