[Portacaval anastomosis with a bypass of lyophilized dura mater. Experimental research in young dogs].

A review of the relevant literature is followed by an account of the use of freeze-dried dura mater prostheses in the construction of porta-cava anastomoses in young dogs. Results of an experiment showed that involution of the dura mater in the new passage between the porta and the cava was followed by the establishment of connective tissue only, and later by the appearance of smooth muscle. The conclusion is drawn that this material gives satisfactory results and is ripe for further development, using various modalities.
