[Vascular sutures using polyglycolic acid in growing arteries. Experimental study].

Vascular anastomoses, carried out in a growing vessel, have certain peculiarities, since with the development of the artery a stenosis may remain in the suture zone which can compromise its success. We believe that the suture material should be absorbable. We carried out an experimental study in which we performed 18 anastomoses of the femoral artery in dogs using 5/0 polyglycolic acid sutures and vascular microsurgery technique. In no case, on reoperating, did we find the existence of stenosis, granuloma, false aneurysm, or disruption. Polyglycolic acid begins to be reabsorbed after one month of evolution, and after two months the reabsorption is almost total. Biological tolerance is optimal.
