Central Pain Syndrome

Central pain syndrome (CPS) is a neurological disorder caused by damage or dysfunction of the central nervous system. Both conservative and operative methods of treatment are used in its treatment, but in most cases their effectiveness is rather low. We are presenting the clinical observation of a 60-year-old patient with spinal cord injury at the level of Th10 due to a car accident that occurred 44 years before the treatment in our clinic, who suffered from phantom pain that occurred after bilateral above the knee amputation because of advanced peripheral vascular disease. Due to the ineffectiveness of the conservative treatment, it was decided to proceed with spinal cord stimulation. The presence of pronounced postoperative changes in the area of spinal cord injury has complicated the transcutaneous placement of trial leads at the L1-L2 and Th12-L1 level. We managed to introduce leads at the level of Th7-Th8 and position them at the level of Th5-Th7. During continuous neurostimulation the pain in the sacrum, in the area of the hip joints, the phantom pain was relieved. The patient stopped using all pain medications. Spinal cord stimulation can be utilized as an alternative treatment for patients with intractable CPS.

Central Pain Syndrome

Central pain syndrome (CPS) is a debilitating condition that affects a large number of patients with a primary lesion or dysfunction in the CNS, most commonly due to spinal cord injury, stroke, and multiple sclerosis lesions. The pathophysiological processes underlying the development and maintenance of CPS are poorly understood. We have recently shown, in an animal model of CPS, that neurons in the posterior thalamic nucleus (PO) have increased spontaneous and evoked activity. We also demonstrated that these changes are due to suppressed inhibitory inputs from the zona incerta (ZI). The anterior pretectal nucleus (APT) is a diencephalic nucleus that projects on both the PO and ZI, suggesting that it might be involved in the pathophysiology of CPS. Here we test the hypothesis that CPS is associated with abnormal APT activity by recording single units from APT in anesthetized rats with CPS resulting from spinal cord lesions. The firing rate of APT neurons was increased in spinal-lesioned animals, compared with sham-operated controls. This increase was due to a selective increase in firing of tonic neurons that project to and inhibit ZI and an increase in bursts in fast bursting and slow rhythmic neurons. We also show that, in normal animals, suppressing APT results in increased PO spontaneous activity and evoked responses in a subpopulation of PO neurons. Taken together, these findings suggest that APT regulates ZI inputs to PO and that enhanced APT activity during CPS contributes to the abnormally high activity of PO neurons in CPS.

Abstract Background Patients with spinal cord injury (SCI) frequently complain of intractable pain that is resistant to conservative treatments. Here, we report the successful application of 1-kHz high-frequency spinal cord stimulation (SCS) in a patient with refractory neuropathic pain secondary to SCI. Case presentation A 69-year-old male diagnosed with SCI (C4 American Spinal Injury Association Impairment Scale A) presented with severe at-level bilateral upper extremity neuropathic pain. Temporary improvement in his symptoms with a nerve block implied peripheral component involvement. The patient received SCS, and though the tip of the leads could not reach the cervical vertebrae, a 1-kHz frequency stimulus relieved the intractable pain. Conclusions SCI-related symptoms may include peripheral components; SCS may have a considerable effect on intractable pain. Even when the SCS electrode lead cannot be positioned in the target area, 1-kHz high-frequency SCS may still produce positive effects.

AbstractInjury to the spinal cord injury with paraplegia, is a rare complication of surgical repair of aortic coarctation recognized immediately post-operatively. We present the case of a 41-year-old male undergoing surgery for restenosis at the site of a repair. Intra-operatively, he suffered inadvertent injury to an intercostal arterial branch during isolation of the aorta below the graft. Over the following months, he developed unusual symptoms involving the legs and genitourinary tract which, only after extensive investigations, were attributed to ischemic damage to the spinal cord related to the surgery. We suspect that similar syndromes reflecting injury to the spinal cord injury may be unrecognized following surgical repair of coarctation.

Purpose of the work. The article is devoted to the first experience of epidural stimulation in the Khanty-Mansiysk Autonomous Okrug at the budgetary institution Surgut Clinical Trauma Hospital. Clinical examples are presented for two main indications for the application of this technique (disease of the operated spine, a consequence of spinal cord injury in combination with chronic neuropathic pain syndrome). Research methods. An assessment of the intensity of pain syndrome was given according to a visual analogue scale, the Pain Detect questionnaire; indicators of anxiety, depression on the HADS scale; quality of life according to the Oswestry questionnaire for a follow-up period of 6-12 months in patients with chronic epidural stimulation. Results. A positive assessment of the action during test neurostimulation was 63.3% (38 patients). Of the established permanent systems, a good result was achieved and persisted for 12 months or more in 96% (24 patients). It was necessary to change the stimulation parameters in 13% (3 patients). Revision of permanent systems was performed in 20% (5 patients), due to the progression of the degenerative-dystrophic process of the spine, damage and migration of system elements. Conclusions. Chronic epidural spinal cord stimulation has established itself as a personalized, highly effective, minimally invasive and safe method of treating chronic neuropathic pain syndromes. Multicomponent corrective action is of scientific interest and requires further study.
