The popliteal artery aneurysms are the most common among peripheral aneurysms and can be treated with stents through endovascular surgery. However, these stents have the same diameter at the proximal and distal part, not being compatible with the vascular anatomy of that segment. The aim of this study was determine the difference between the diameter of the distal third of the femoral artery and the diameter of the posterior tibial artery, and to obtain the diameter of others arteries of the lower limb. We study 28 formalized cadavers of adult individuals of both sexes, which were dissected in the corresponding region. The following arterial diameters were recorded: the distal third of the femoral artery, distal part of the popliteal artery, anterior tibial artery and posterior tibial artery. In males from the distal third of the femoral artery to the posterior tibial artery there was a narrowing of 27.92% (p < 0.0001). In women, the reduction was 52.61 % (p<0.0001). By comparing the diameter of the distal third of the femoral artery between the sexes, a statistically significant difference was obtained (p<0.0497), as well as between the posterior tibial artery diameters (p < 0.0142). These data are of clinical importance for endovascular surgery procedures and may reduce complications in such procedures. Stents must adapt to these differences in diameter.
