Summary

This study aimed to determine the impact on outcomes when recipient veins with reflux were used for LVA for the treatment of unilateral lower limb lymphedema.

Detailed description

The use of recipient veins with reflux for lymphaticovenous anastomosis (LVA) is discouraged because of the common belief that it may lead to venous-lymphatic reflux (VLR), a phenomenon in which venous blood is refluxed into the lymphatic lumen after anastomosis, which can lower the long-term patency rate. However, this concept has yet to be validated.

Conditions

• Lymphedema

Interventions

Type	Name	Description
