RESUMO

Truncular venous malformations and acquired functional or anatomical venous occlusions (or sub-occlusions) can be the cause of secondary lymphedema and even the cause of primary lymphedema when they are associated with lymphatic malformations (lymphangiodysplasia - LAD I, lymphadenodysplasia - LAD II, or a combination of both) in pediatric patients. This understanding recognizes the shared and successive embryogenesis of both systems. These conditions can exhibit hypertension in the venous pedicles intended for lymph-venous anastomosis, and this finding would be a formal contraindication to the procedure. However, this hypertension is a rarely considered condition and is not commonly identified. As a technique to solve this problem, we have combined Nielubowicz, Olszewski, Campisi, and Palma's proposals and created a lymph-venous anastomosis from the side with lymphedema and venous hypertension (lymphatic donor and venous recipient) with an internal suprapubic saphenous venous bridge (from the normal side to the lymphedematous side with venous hypertension) to enable a crossed inguinal lymphatic/venous rescue. We believe this newly synthesized approach will allow better clinical care of pediatric patients with complex and combined lymphatic-venous malformations and is worthy of further investigation.
