Cross-femoral venous bypass in combination with tumor resection.

The cross-femoral venous bypass procedure (also known as the Palma/Dale procedure) was introduced for unilateral iliac or common femoral vein occlusions resulting in chronic deep venous insufficiency. We have utilized the procedure successfully in a patient who required extensive pelvic tumor resection involving sacrifice of pelvic venous collateral channels and unilateral ligation of external, internal, and common iliac veins. The case report and review of the literature are presented.
