Pathological Changes of the Blood Vessel Wrapped in Teflon(polytetrafluoroethylene) Felt in the Cat

ABSTRACT

Teflon(polytetrafluoroethylene) felt it utilized well as an implanted material for suboccipital microvascular decompression of hemifacial spasm, trigeminal neuralgia and glossopharyngeal neuralgia. Although the effect of Teflon has been studied widely, there are no studies about the effect on the cerebral vessels. The authors have examined the porribilities of the change of cat cerebral vessels and femoral vessels by direct contact the Teflon. There was no changes of vessel wall. Also the authors couldn't find any aneurismal changes of vessels wall. Teflon han only effect of foreign body reaction. This experiment shows that Teflon is relatively inert when used for microvascular decompression.
