Experimental and clinical results of the application of Dallon prostheses in vascular surgery are presented. Dallon prostheses are produced in the Medical Materials Department of the Research Development Centre of the Knitting Industry in łódź. They are contained in disposable radially sterilized wrappings. The experiments were performed on 17 mongrel dogs and the process of healing in was observed after three and six months. The process was similar to the healing in of other porous, synthetic prostheses. In 37 patients operated because of the artheromasia bypasses or vascular flaps of Dallon prostheses were implanted. The results of experimental and clinical research proved that the radially sterilized Dallon prostheses have similar properties like the prostheses produced be well known foreign firms, and are very useful in arterial reconstruction.

The replacement of affected blood vessels of the polymer material can cause imbalances in the blood haemostatic system. Changes in blood after the implantation of vascular grafts depend not only on the chemical composition but also on the degree of surface wettability. The Dallon H unsealed hydrophilic knitted vascular prosthesis double velour was assessed at work and compare with hydrophobic vascular prosthesis Dallon.

Vascular prostheses produced on the basis of polyester are today commonly used in vascular surgery. To improve their biofuncionality special technologies are used, among them double knit and hydrophile feature enrichment. These modifications could cause the local activation of leukocytes to produce the mediators of inflammatory reaction, which in turn leads to hyperplasia of endothelium and other dangerous complications.

Author on the ground 124 of artificial grafts Dallon H grafted in years 2000--June 2002 in Department of Vascular, General and Transplantation Surgery in Wroclaw with protracted ischaemia of lower limbs, represents own experiences for observations of useful features this artificial graft. The hydrophility of these grafts, at maintenance all of other comparable features with grafts of westerly firms causes, that Dallon H I gained oneself large acknowledgement as many-sided artificial grafts alternative to vascular prosthesis of renowned westerly firms.

Vascular prostheses made of polyester or polytetrafluoroethylene fibres are most frequently used nowadays. Woven polyester prostheses are sealed following the suturing in the circulatory system, but they cause a tissue reaction. Knitted polyesters grafts cause a lesser tissue reaction, but demand intraoperative sealing.
