[A plastic substitute for the superior sagittal sinus in pigs]

The substitute of the superior sagittal sinus by a new method namely a vessel prosthesis (Gore-Tex) and special connecting pieces in relationship with drug treatment is represented. The method is very simple and can also be carried out by microsurgically untrained operators. Moreover, this method allows a clear faster operation without using a bypass. The sinus was ligated, partially resected or incised and replaced by the described prosthesis in 15 pigs. 3 experiments were without any assertion at all. The sufficiency of the prosthesis was provable in 10 of the 12 remaining pigs. With that a high sufficiency quota was obtained in comparison with the literature. An open prosthesis for a longer time makes possible the formation of a collateral circulation. Furthermore, the prosthesis enables the microsurgical implantation of bigger pontine veins.
