Traditionally, gonadal vein embolization is done by placing coils 10-20% over sized compared to the target vein. Often 10 or more coils are required to treat a single vein. Each coil only treats a short segment of vein leaving other segments open. The "uncoil coil" technique utilizes large diameter longer coils allowing a gonadal vein to be treated with 2-3 coils. The procedure is faster, exposes the patient to less radiation and reduces the risk of maldeployment and migration.
