Fibro-Lipo-Lymph-Aspiration With a Lymph Vessel Sparing Procedure to Treat Advanced Lymphedema After Multiple Lymphatic-Venous Anastomoses: The Complete Treatment Protocol

Background: In lymphedema, excess adipose tissue occurs with progression of the disease because of chronic lymph stasis, impeding lymphatic flow. Recently, liposuction has been used as a less-invasive procedure to remove this excess tissue. Given the existing poor lymph drainage in patients with lymphatic diseases, extra caution should be taken to avoid damaging lymphatic vessels during liposuction. We developed a new technique (Fibro-Lipo-Lymph-Aspiration with a Lymph Vessel Sparing Procedure [FLLA-LVSP]) to improve chronic swelling in patients with advanced lymphedema. The FLLA-LSVP highlights the superficial lymphatic pathways in the treated limb. This visibility allows surgeons to avoid these pathways, while removing the maximum amount of excess tissue. Method: One hundred forty-six patients with primary or secondary lymphedema that had already been treated by lymphatic microsurgery, in Genoa, Italy, were included in this retrospective study. All patients had residual fibrotic/adipose tissue, resistant to conservative treatments. Indocyanine green fluorescent dye and Blue Patent Violet dye were injected laterally/medially to the main superficial veins at the wrist/ankle of the limb to be treated. Using a photodynamic camera, the superficial lymphatic network was made visible and sketched onto the skin in indelible ink. After the microlymphography, the excess adipose tissue was carefully aspirated. Preoperative and postoperative excess limb volume was calculated using cir...
