2. Fig. 1
Numbers and types of umbilical vein grafts implanted from 1975 to Grafts implanted since 1990 were prepared by new manufacturer. Each bar since 1986 represents total umbilical vein bypass grafts for that year. Bottom numbers are popliteals, and above those are crurals. See Dardik et al15 for details for first decade. UV, Umbilical vein graft; Pop, popliteal.

3. Fig. 2
Type, number, and percentage of distal anastomoses of umbilical vein grafts for 1990 to Shift of 10% occurred from popliteals to crurals in comparison of two decades. n indicates the numbers of bypass grafts. UV, Umbilical vein graft; pop, popliteal; BK, below-knee; AK, above-knee; AT, arterior tibial; PT, posterior tibial.

5. Fig. 4
Comparative cumulative graft patency rates for popliteal reconstuctions with use of umbilical vein grafts during decades from 1975 to 1985 (bold lines) and from 1990 to 2000 (light lines and italics ). Difference in curves was statistically significant in comparison of decades with log-rank test (P <.05). UV, Umbilical vein graft; Pop, popliteal; SE, standard error.

Comparative cumulative graft patency rates for crural reconstuctions with use of umbilical vein graft during decades from 1975 to 1985 (bold lines) and from 1990 to 2000 (light lines and italics ). Differences between curves were statistically significant (P <.05). UV, Umbilical vein graft; SE, standard error.

Comparative cumulative limb salvage rates for popliteal and crural reconstuctions with use of umbilical vein graft during decades from 1975 to 1985 (bold lines) and from 1990 to 2000 (light lines and italics ). Differences between any curves were not statistically significant. UV, Umbilical vein graft; Pop, popliteal; SE, standard error.
