Abstract

AIM: Ethylene vinyl alcohol copolymer (EVOH), its organic solvent dimethyl sulfoxide (DMSO), and N-Butyl 2-Cyanoacrylate (NBCA) are widely used in neurovascular embolization procedures and yet with potential risk of cytotoxicity. The aim of this study was to evaluate the toxic effect of EVOH-DMSO, its solvent DMSO and NBCA on cerebral parenchyma in a rabbit model. MATErIAL and METHods: Forty-eight albino male rabbits were divided into 6 groups based on the substance injected into the parenchyma; normal saline, DMSO, NBCA, 6% EVOH-DMSO and 20% EVOH-DMSO and control group. At 72 hours the subjects were sacrificed and brain samples were harvested for histopathological examination and lipid peroxidase measurements. rEsuLTs: Neuronal degeneration and inflammatory reaction in the brain parenchyma was prominent especially in DMSO group and EVOHDMSO groups. Furthermore, the extent of degeneration and inflammatory reaction was related to the concentration of the embolic agent in the EVOH group. Lipid peroxidase activity was significantly increased in the NBCA group as compared to all but to 20 % EVOH-DMSO group. CoNCLusIoN: EVOH and its solvent DMSO cause degeneration and inflammatory reaction in brain parenchyma and for EVOH this reaction was appeared to be dose dependent.

Özet

AMAÇ: Etilen Vinil Alkol Kopolimer (EVOH), organik solventi dimetil sülfoksid (DMSO) ve N-Bütil 2-Siyonoakrilat (NBCA) potansiyel olarak sitotoksik özellikler taşıyan ve sıklıkla nörovasküler embolizasyon işlemlerinde kullanılan maddelerdir. Bu çalışma ile EVOH-DMSO ile solventleri olan DMSO ve NBCA'nın serebral parankim üzerindeki toksik etkileri deneysel tavşan modelinde araştırılmıştır.yÖNTEM ve GErEÇLEr: Çalışmada kırksekiz erkek albino tavşan kullanıldı ve beyin parankimine enjekte edilen maddelere göre tavşanlar 6 gruba ayrıldı. Kontrol grubu dışındaki tavşanlara normal salin, DMSO, NBCA, %6'lık EVOH-DMSO ve %20 lik EVOH-DMSO verildi. Tavşanlar yakın nörolojik takip altında tutuldu. 72 saat sonra tavşanlar sakrifiye edildi ve beyin dokusu çıkarılarak histopatolojik inceleme ve lipid peroksidaz ölçümleri için hazırlandı. BuLGuLAr: Özellikle DMSO ve EVOH-DMSO gruplarında nöronal dejenerasyon ve inflamatuvar reaksiyonlar belirgindi. Dahası, EVOH grubunda dejenerasyon ve inflamasyon düzeyi, kullanılan embolizan ajan konsantrasyonu ile ilişkiliydi. Lipid peroksidaz aktivitesinin %20'lik EVOH-DMSO grubu dışındaki diğer gruplara nazaran belirgin olarak NBCA grubunda arttığı tespit edildi. soNuÇ: EVOH ve solventi DMSO beyin parankiminde dejenerasyona ve inflamatuvar reaksiyona yol açmaktadır ve bu etki EVOH için doz ilişkilidir.
