The objective of present paper was to carry out an anatomic study of the gastrocnemic veins in adult human cadavers by dissection. This study was made with 20 human adult cadavers, all male, fixed and maintained in 10% formaldehyde solutions. Bodies presenting detectable macroscopic alterations, such as fracturations (broken bones) deformities, malformation and surgery done in the popliteal region were excluded from the observation. The dissection and observation of these veins was done without optical tools. All gastrocnemic veins were dissected from their emerging of the heads of the gastrocnemic muscle to the place of draining. In order to take the measurements, a digital pachymeter was used. Descriptive statistics were used for the variables of the study. In 80 gastrocnemic dissected muscle heads 438 gastrocnemic heads were found, 233 of which on the right peg and 205 on the left leg. 95 main trunks were identified, 51 of which on the right leg and 44 on the left leg. The average extension of these trunks was 2.17 cm on the right leg and 2.0 cm on the left leg. Of the total of the main gastrocnemic trunks, 83 end in the popliteal vein and 12 in other veins. In 30 gastrocnemic trunks of the right leg 32 valves were found and the lack of valves in 21. On the left leg 33 valves were found on 30 gastrocnemic trunks and the lack of valves on 14 trunks. Of the anatomic point of view, the gastrocnemic veins present an arrangement in form of a net. The right leg showed a major quantity of these veins than the left leg. The anatomic arrangement of these veins is rather complex and assumes the typical disposition of a net. Four different types of nets were described. The average length and number of valves of the gastrocnemic trunk were similar on both legs. Most of the gastrocnemic trunks emerge into the popliteal vein. The statistic treatment applied indicated that there is significance of the variation of extension of the main gastrocnemic veins, when considered by type of net and head of the gastrocnemic muscle.
