Variations of Saphenous Veins: Case Report and Literature Review.

Introduction: the superficial veins of the lower limbs, usually used as an autograft for arterial bypass surgery, can be affected by chronic venous insufficiency (CVI) and complications such as thrombosis, ulcers and thromboembolism. In addition to full knowledge of the anatomy, it is essential to consider anatomical variations and their clinical and surgical implications. Case Report: this paper presents the atypical pattern of superficial veins in the right lower limb during the dissection of the intact formaldehyde-preserved cadaver of an adult man from Brazil. The great saphenous vein (GSV) extension does not course in a single trunk, but as an anastomotic network connected with the small saphenous vein (SSV). The elongated aspect of anterior cutaneous femoral vein (ACFV) which runs in the interfascial compartment from the knee to the right femoral triangle. Review: a literature review on aspects related to the unusual path of superficial venous drainage of the lower limbs was carried out using the MeSH (Medical Subject Headings) terms: "Saphenous Vein" AND "embryology", "Saphenous Vein" AND "Anatomic Variation". Conclusion: these morphological findings must be taken into account by clinicians because of the possible physiopathological implications of anatomical remodeling, flow by-passing and structural modifications related to variation of these veins.
