FIELD: vascular surgery. SUBSTANCE: after removal of autovein, the latter is cut longitudinally along its whole length. Thus formed vein tape is coiled with its intima inward on cylindrical template with controlled diameter in such a manner that edges of the tape were in touch with each other. Cylindrical template is made in the form of bunch of spokes fixed for radial divergence on two ring clamps. After that, one applies discontinuous-and- continuous nonabsorbable suture on adjoining edges of tape. Intima is repeatedly irrigated by heparin-containing solution. Defect of venous vessel is replaced with autovein. EFFECT: enabled formation of prosthesis with diameter strictly corresponding to diameter of injured vessel.
