Experimental Artery Graft Angulation

Arch Surg. 1962;85(2):173-175. doi:10.1001/archsurg.1962.01310020003001

Experimental studies concerning the replacement of arteries with arterial and venous grafts—autogenous, homologous, and heterologous—and various cloth prostheses have been well-documented in the surgical literature.1-4 In the majority of these reports, a fixed artery, such as the abdominal aorta, has been the principal artery replaced, while only a few publications have been concerned with the behavior of grafts when they are used to replace an artery that crosses a flexion crease. The purpose, therefore, of this report is to present a series of laboratory experiments in which arteriography was employed to study the effect of flexion on various implanted arterial substitutes.

Methods  Thirty-eight mongrel dogs weighing 20-30 kg. were anesthetized with intravenous sodium pentobarbital. Under sterile operating conditions the common iliac artery and femoral artery of each animal were mobilized through separate incisions, and a tunnel connecting the 2 sites was made by forcible dilatation of the infrainguinal area
