title: Experimental evaluation of microarterial grafts in rats and rabbits: long-term histological studies.
abstract: This experimental study was done to compare the fate of microarterial grafts versus microvenous grafts. Based on morphological aspects, patency rates, and histological features, the arterial grafts gave better long-term results than the venous grafts--due mainly to an absence of subintimal fibrotic changes in the microarterial grafts.
