ObjectivesSaphenous nerve injury is the most common complication after surgical treatment of varicose veins. The aim of this study was to establish its frequency at great saphenous vein long stripping when four methods of surgery were applied.MethodsEighty patients were divided into four groups depending on different stripping methods. Sensory transmission in saphenous nerve and sensory perception of shank were examined before surgery and two weeks, three and six months afterwards with clinical neurophysiology methods.ResultsIn 36% of patients, surgeries caused the injury of saphenous nerve mainly by proximal stripping without invagination (65%, group I). Transmission disturbances ceased completely after three months in patients undergoing distal stripping with invagination (group IV), while in group I they persisted for six months in 35%. Group IV patients were the least injured and group I the most.ConclusionNeurophysiological findings may suggest that distal stripping with vein invagination gives the best saphenous nerve sparing.

AbstractThe management of elimination of the pathological reflux in the saphenous vein has been developed recently by introducing the endovenous thermal techniques (EVTA), which have become the first line treatment. However, thermal techniques require tumescent infiltration, what may be the cause of discomfort. Furthermore, the use of EVTA has a potential risk of thermal damage of superficial nerves and requires to wear stocking after the procedure.Non-thermal non-tumescent techniques (NTNT) were proposed as a valid, safe and effective alternative to EVTA with significant clinical improvement, high complete occlusion rate and high posttreatment patient satisfaction. The most common novel NTNT are catheter-directed cyanoacrylate adhesive closure (CAC) and mechanochemical ablation.In the paper an overview of the currently available data regarding the NTNT efficacy and safety are presented.Based on the literature, NTNT has a high efficacy, comparable with the EVTA techniques, with an acceptable risk increase. However further studies with long-term results are needed also with regard to safety aspects.
