Key result
Autogenous vein grafts developed progressive subendothelial proliferative lesions, causing up to 90% luminal narrowing in coronary grafts by 6 to 12 months.

Progressive vein graft narrowing warrants surveillance post-CABG; leaves open mechanisms and prevention strategies.
Observational
What are the histopathological changes that occur in autogenous vein grafts used for arterial bypass over time?
Autogenous vein grafts develop progressive subendothelial proliferative lesions leading to significant luminal narrowing, likely driven by recurrent endothelial damage.
Jones et al. (1973) conducted an observational in Autogenous vein grafts. Autogenous vein grafts was evaluated on Pathological lesions in vein grafts. Autogenous vein grafts developed progressive subendothelial proliferative lesions, causing up to 90% luminal narrowing in coronary grafts by 6 to 12 months.
