[Comparison of peritoneal patch and vascular prosthesis monitored with isotopes and parameters of humoral and cell...

The aim of this experimental study was to assess the reaction of peritoneal patch and vascular graft after implantation in arterial system. We compare complement haemolytic activation CH-50%, serum elastase and scintigraphy using Tc99 labeled leukocytes. There were significant differences in parameters of humoral and cell-mediated response between implantation of peritoneal patch and vascular graft. Twelve months later histological examination was made to determine healing processes of implanted materials. The results of this study are encouraging and confirm benefits of peritoneal patch in vascular surgery creating a new possibilities of angioplasty.
