Using gore-tex strip film sheet in the fresh cadaveric cow brain for evaluating brain protection

Abstract

Aim: The aim of this experimental study was to evaluate the use of gore-tex stripfilm sheet in the protection of brain tissue from the harmful mechanical effect of metallic microsurgical instruments. Material and Method: Thirty uncovered fresh cadaveric cow brains were equally divided into two groups: group with the gore-tex stripfilm sheet (Group I) and without gore-tex (Group II). In Group I, the gore-tex stripfilm sheet, 40 mm in length and 12 mm in width, was sprawled over the left lateral side of the interhemispheric sulcus of anterior brain surface. The mechanical traumatic effects of metallic surgical instruments were divided into three groups : minor, moderate, and severe. Results: In Group I (n=15), the number of minor injured brains was found to be 10 (66. 67%). In Group II (n=15), the number of minor injured brains was found to be 3 (20%). On the contrary, the number of moderately injured brains parenchyma in Group I cow brains was estimated to be 3 (20%). However, the number of moderately injured brains in Group II was found to be 8 (53. 33%). The number of severe injury was found to be 4 (26. 67%) in Group II. The number of same injury was found to be 2 (13. 33%) in Group I. Conclusions: In conclusion, this study showed that protecting the naked brain tissue from the mechanical injury effect of metallic microsurgical instruments using the gore-tex stripfilm sheet is feasible. It is believed that this material might contribute to the practical microneurosurgery in protecting the brain tissue.
