Abstract

Purpose: Repairing of the duramater is one of the major factor that effects the mortality andmorbidity of patients after neurosurgical approaches. The gold standard for repairing ofduramater is watertight suture or duraplasty with autografts such as pericranium and/ortemporal fascia. Sometimes edges of the dura mater generally are shrunken and the watertightsuture of the dura becomes impossible especially in emergency conditions. In the presentstudy, we aimed to determine the most effective artificial dural graft in experimental duraldefect in rats.Materials and Methods: Twenty eights wistar albino rats weight ranging from 280-320grams and equal numbers of male and female were used. The animals were divided into fourgroups. Control (n=7 Group-1), collagen matrix graft (n=7 Group-2), cellulose graft (n=7Group-3) and teflon graft (n=7 Group-4). Rats were sacrificed after 30 days and theirdamaged dura were removed and sections were taken. All histological preparations examinedusing light microscope. Histological analysis focused on fibroblastic activation, new capillaryformation, inflammatory reaction, foreign body reaction and capsule formation and resultswere compared.Results: While fibroblastic activation was observed most frequently in teflon graft group,new capillary formation, inflammatory reactions and capsule formation were most frequentlyseen in cellulose grafts group.Conclusion: This animal model for artificial dural grafts suggest that cellulose was the mosteffective dural substitute for repairing of defective dura.

Özet

Amaç: Duramater tamiri nöroşirürjikal yaklaşımlardan sonra mortalite ve morbiditeyietkileyen en önemli faktörlerden biridir. Altın standart duramaterin, su geçirmez şekildesütüre edilmesi veya perikranium, temporal fasya gibi otogreftlerle duraplasti yapılmasıdır.Bu işlem özellikle acil durumlarda dura kenarlarının kısalması nedeniyle mümkünolmayabilir. Çalışmamızda ratlarda deneysel dura defekti yaparak en etkili yapay dura greftinibelirlemeyi amaçladık.Materyal ve Metod: Ağırlıkları 280-320 gr arasında değişen, eşit sayıda erkek ve dişi toplam28 adet wistar albino cinsi rat kullanıldı. Hayvanlar, kontrol (n=7 Grup-1), kollojen matriksgreft (n=7 Grup-2), selülöz greft (n=7 Grup-3) ve teflon greft (n=7 Grup-4) olmak üzere 4gruba ayrıldı. Ratlar 30 gün sonra kesilip hasarlı dura mater kısımları çıkarıldı ve kesitlerialındı. Tüm histopatolojik kesitler ışık mikroskobu kullanılarak yapıldı. Histolojik çalışmadafibroblastik aktivite, yeni kapiller oluşumu, inflamatuar reaksiyon, yabancı cisim reaksiyonuve kapsül formasyonu değerlendirilip sonuçlar karşılaştırıldı.Sonuç: Fibroblastik aktivite en fazla teflon grubunda görülürken yeni kapiller oluşumu,inflamatuar reaksiyon ve kapsül oluşumu en fazla sellüloz grubunda görüldü. Karar: Budeneysel model, selülözün hasarlı duramater tamirinde en etkili yapay dura grefti olduğunugöstermi tir.
