Experimental evaluation of the net "Dallop" covered with collagen as the dural substitute.
Evaluation of the usefulness of the net "Dallop" produced by Tricomed Lódź covered with collagen to the dural defects reparation was analysed. This new original product of Lódź Technical University was compared with widely used in neurosurgery "Zenoderm" produced by Ethicon and "Duratexol" produced by Czechoslovakia. The trial was conducted on 38 rabbits: 4 as a control group (just an original dura sutured after incision with Mersilk Ethicon sutures), 19 with implanted the net "Dallop" covered with collagen, 11 with the "Zenoderm" and 4 with the "Duratexol". Animals were sacrificed after 3, 14, 30 or 90 days after surgery. There were no significant differences between all analysed groups in clinical, macroscopical and morphological investigations. No negative local reactions in histopathological evaluation of the net "Dallop" covered with collagen were observed. The results of our investigations show that the net "Dallop" covered with collagen seems to be the "Zenoderm" and the "Duratexol" dural substitute.
