SANTOS, Carlos Adriano Silva dos et al. Valves of the common brachial vein: anatomical study. J. vasc. bras. [online]. 2007, vol.6, n.1, pp. 35-41. ISSN 1677-5449. http://dx.doi.org/10.1590/S1677-54492007000100006.
BACKGROUND: A great part of venous insufficiencies is due to valve incompetence. Valved venous grafts in the insufficient segment are a surgical alternative. OBJECTIVE: To describe the anatomy of the common brachial vein valves. METHODS: We used 30 male corpses of varied races with their upper limbs articulated to the trunk. They were preserved in formol and fixed in a 10% formol solution. Exclusion criteria were presence of disarticulation in one limb or deforming alterations in the topography of assessed structures. RESULTS: The total number of identified valves was 28 in the right arm and 33 in the left arm, 15 of them in the right proximal segment and 21 in the left proximal segment. More than 91% of the valves were bicuspid and parietal. CONCLUSION: We conclude that the common brachial vein often presents bicuspid and parietal valves.
