Abstract

GABRIELLI, Carla et al. ANATOMICAL AND BIOMETRIC ASPECTS OF THE DORSALIS PEDIS ARTERY IN HUMANS. Rev. chil. anat. [online]. 2001, vol.19, n.3, pp.325-330. ISSN 0716-9868.  http://dx.doi.org/10.4067/S0716-98682001000300015.

The feet are important in the weight support, biped posture, locomotion and equilibrium. The attempts of its revascularization are frequent, through the arterial bypasses, with the purpose of avoid amputations.  Due to the dorsalis pedis artery (DP) is used as flow receptor vessel, we study its anatomical and biometrics characteristics. We used (utilized) 30 feet from 15 Brazilian adult cadavers, of both sexes, from the Department of Morphological Sciences of the Universidade Federal de Santa Catarina, Brazil. The arteries were injected with neoprene latex (Artifix L14) stained red and the dorsum of foot was dissected under magnification. The DP was present in 100%; the average diameter in its origin was 3.16 ± 0.67 mm  and at level of its termination was 2.19 ± 0.71 mm. The DP length was 78.32 ± 13.58 mm. The DP placed between the extensor hallucis longus and extensor digitorum longus tendons in 90% of the cases. Its relationship with the cutaneous branch of the deep fibular nerve was variable: the branch was medial to DP in 33.3%; it was lateral in 13.3% and it crossed superiorly the artery (usually from medial to lateral) in 26.7%. The branch did not related with the DP in 10%, because it was replaced by endings of the superficial fibular nerve. In the remaining 16.7% we observed other relationship patterns, as the overlaying of the branch on the DP. In respect to the DP collateral branches, the most frequent number of medial tarsal arteries was two (56.6%), equal to the lateral tarsal arteries (60%); the arcuate artery was present in only 26.7%. The DP has compatible anatomical characteristics with the arterial bypasses construction, but it must have care in those cases which the nerve crosses the artery or superposes it, to avoid its  lesion during of surgical procedures
