BACKGROUND: Thermal @entity1897 is a known complication of @entity1931 ( @entity1931 ) of the small saphenous vein ( @entity12432 ). Therefore, the main objective of this anatomic study was to define a safe zone in the lower leg where @entity1931 of the @entity12432 can be performed safely. METHODS: The anatomy of the @entity12432 and adjacent nerves was studied in 20 embalmed @entity1 specimens. The absolute distances between the @entity12432 and the sural nerve (SN) (closest/nearest branch) were measured over the complete length of the leg (>120 data points per leg), and the presence of the interlaying deep fascia was mapped. The distance between the @entity12432 and the @entity4957 ( @entity4957 ) and the common peroneal nerve was assessed. A new analysis method, computer-assisted surgical anatomy mapping, was used to visualize the gathered data. RESULTS: The distance between the @entity12432 and the SN was highly variable. In the proximal one-third of the lower leg, the distance between the vein and the nerve was <5 mm in 70% of the legs. In 95%, the deep fascia was present between the @entity12432 and the SN. In the distal two-thirds of the lower leg, the distance between the vein and the nerve was <5 mm in 90% of the legs. The deep fascia was present between both structures in 15%. In 19 legs, the SN partially ran beneath the deep fascia. In the saphenopopliteal region, the average shortest distance between the @entity12432 and the @entity4957 was 4.4 mm. In 20%, the distance was <1 mm. The average, shortest distance between the @entity12432 and the common peroneal nerve was 14.2 mm. The distance was <1 mm in one leg. CONCLUSIONS: At the saphenopopliteal region, the @entity4957 is at risk during @entity1931 . In the distal two-thirds of the lower leg, the SN is at risk for (thermal) damage due to the small distance to the @entity12432 and the absence of the deep fascia between both structures. The proximal one-third of the lower leg is the optimal region for @entity1931 of the @entity12432 to @entity16 ; the fascia between the @entity12432 and the SN is a natural barrier in this region that could preclude (thermal) damage to the nerve.
