NEUROPHYSIOLOGICAL MONITORING IN TETHERED CORD SYNDROME SURGERY: TWO CASE REPORTS

Abstract Tethered cord syndrome (TCS) is a neural tube defect that results from an attachment of the conus medullaris that limits movement of the spinal cord within the spinal canal. Temporary and permanent neurological complications may be observed after microsurgical release of the spinal cord. Currently, intraoperative neuromonitorization is used to decrease morbidity during TCS microsurgery.Pre- and postoperative results for 2 patients with tethered cord syndrome followed by intraoperative neuromonitorization are reported here. Key words: Tethered cord syndrome, intraoperative neuromonitorization, electromyography, motor evoked potentials, somatosensory evoked potentials. Ozet Gergin omurilik sendromu konus medullarisin spinal kanalda hareketinin yetersizligi ve/veya dusuk yerlesimli olmasiyla sonuclanan bir noral tup defektidir. Mikrocerrahi olarak serbestlestirilmesini takiben kalici veya gecici norolojik komplikasyonlar gozlenebilir. Gunumuzde gergin omurilik sendromu mikrocerrahisi esnasinda morbiditeyi azaltmak icin intraoperatif noromonitorizasyon kullanilmaktadir.Bu olgularin sunumu ile, intraoperatif noromonitorizasyon modaliteleri ile takip edilen gergin omurilik sendromu olgularinin peroperatif ve postoperatif sonuclari bildirildi. Anahtar kelimeler: Gergin omurilik sendromu, intraoperatif noromonitorizasyon, electromitografi, motor uyarilmis potansiyel, somatosensoryel uyarilmis potansiyel.
