    Abstract:
    The objective of this study was to evaluate the efficiency of multiple vascular reconstructive procedures in the presence of an occluded synthetic graft. Over a four year period seventy-seven occluded synthetic grafts were treated with urokinase and reconstruction. Follow-up ranged from 1 to 1627 days (4 years, 5 1/2 months). Kaplan-Meier and generalized Wilcoxon test were used to determine patency and limb salvage rates. The cases were divided into three groups according to the number of previous reconstructive events. Group I consisted of patients that had undergone one previous vascular reconstructive procedure. Group II consisted of patients that had undergone two previous vascular reconstructive procedures. Group III consisted of patients who had undergone three or more previous reconstructive procedures. In Group I, the one, two, and three year patency rates were 48.6%, 34.7%, and 26.0% and the limb salvage rates were 76.2%, 67.9%, and 67.9% for one, two, and three years respectively. The Group II patency rates were 41.9%, 24.4%, and 16.3% and the limb salvage rates were 73.7%, 66.3%, and 66.3%. The Group III patency rates were 31.8%, 5.5%, and 5.5% and the limb salvage rates were 76.6%, 54.8%, and 54.8%. The patency rate was significantly reduced when Group III was compared to Group I (p < 0.01). There was no statistically significant difference in limb salvage rates between any of the groups. These results indicate that the number of secondary vascular reconstructive procedures combined with thrombolysis had no correlation with the prognosis of limb salvage.(ABSTRACT TRUNCATED AT 250 WORDS)
