3. Fig. 2
Cumulative life-table secondary patency rates for in situ and reversed vein grafts ≤3.0 mm in MDD. Standard error is represented by the vertical bars. The patency difference between the two types of grafts was not statistically significant (p > 0.50).

Arteriograms demonstrating the development of hyperplasia and marked narrowing of the lumen over the entire length of an in situ vein graft. Left: intraoperative. Right: 6 months after operation. Histologic examination of this graft 1 month later revealed diffuse intimal and subintimal fibrosis and hyperplasia.
