Incidence of myointimal hyperlapsia late in arterial prosthetic anastomosis with and without venous ring: Prospective, randomized and paired experimental study
Incidencia de la hiperlapsia miointimal tardía en anastomosis protésico arteriales con y sin anillo venoso: Estudio experimental prospectivo, aleatorio y pareado
Resumen:
Various studies conducted at internationalleve/ have shown a significant incidence of failures ofprothesico-arterial bridges, particular/y those in whichdistal anastomosis is /ocated at infrapoplitea/ leve/,in sma/1 calibre arteries. Primary permeability isapproximately 40% after one year and 12% after 4years, evolution. In a paper concerning experimentalwork carried out by the Basic Surgery department,which was presented to the Uruguayan Congress ofSurgery in 1997, we showed that there was a /owerincidence of miointimal hyperplasia (MIH) after onemonth 's evolution in distal porthesico-arterial anastomosiswith venous ring, in sheep.
