Experimental investigations on the possibility of transplantation of venous grafts stored at low temperatures.
At the Laboratory of Experimental Surgery, Institute of Haematology in Warsaw 13 dogs received homografts of venous patches stored at low temperatures to fill defects in the wall of the lower caval vein. Venous patches were prepared from segments of femoral veins and were placed in 1.41 M DSMO and stored at the temperature of liquid nitrogen. The authors describe the methods of obtaining venous patches, the technique of freezing and defreezing of grafts, and details of operations. Full healing in of grafts took about 15 days. The results of histological examinations of grafts obtained during planned autopsies between 12 and 29 days after application of the graft are discussed.
