The appropriate length of great saphenous vein stripping should be based on the extent of reflux and not on the intent to avoid saphenous nerve injury.

Objective: To investigate the effect of stripping the below knee great saphenous vein (GSV) segment on varicose vein recurrence as well as any disability induced after saphenous nerve injury (SNI) during a 5-year period.

Methods: One hundred and six limbs (86 patients, 64 female, mean age 46 years), that underwent GSV stripping, to the knee or ankle level, were prospectively followed up at 1 month and 5 years postoperatively with clinical examination and color duplex imaging (CDI), in order to evaluate SNI and the development of recurrence. The extent of GSV stripping complied with preoperative CDI in 84 limbs (79%) that were subjected to GSV stripping to the ankle and full abolishment of duplex-confirmed reflux.
