Relaciones anatómicas de la vena safena magna con el nervio safeno a nivel talocrural

Abstract

Despite the clinical and anatomical significance of the anatomical relationship of the saphena magna vein (SMV) and the saphenous nerve in (SN) in the talocrural region there are few studies in the literature. Thirty feet of adult formolized cadavers of both sexes were dissected describing the origin of the SMV and its relation with the SN in the talocrural region. Distance between the SN and the SMV was measured at the apex level, anterior margin and at 1 cm from the upper margin. The SMV originated from the medial marginal vein and dorsal venous arch. Anatomical relation between the SMV and the SN is varied, traveling anterior the SN 63.3%, and posterior the SMV 30%; in 6.7% the SN divided in two branches which joined anterior and posterior to the SMV. The distance of the SMV and the SN medial malleolus apex was 10.75mm ±3.06 and 13.38±2.82 mm. SMV distance to anterior margin of the medial malleolus was 0.53 mm± 0.51. The relation between the SMV and SN is important for clinicians particularly at the time of determining peripheral venous access not as frequent in veins of the talocrural region.
