Background: Vascularized submental lymph node (VSLN) transfer is an emerging approach for extremity lymphedema. This study investigated the long‐term outcome and venous complications of VSLN for unilateral lower extremity lymphedema. Methods: Between 2010 and 2018, patients who underwent VSLN for unilateral lower extremity lymphedema were retrospectively evaluated. Patient demographics, operative records, complications, circumferential improvement, and episodes of cellulitis were analyzed. Further comparisons were performed between different types, numbers, and techniques of venous anastomoses. Results: A total of 75 VSLNs in 70 patients survived, giving a 100% success rate. Six flaps (8%) had venous complications (VC group) and 69 flaps (92%) did not (No‐VC group). There were no statistical differences in types, numbers, and techniques of anastomoses between two groups ( P = .65, 1, and .56, respectively). At a mean follow‐up of 32.0 ± 23.0 months, mean circumferential improvement and episodes of cellulitis between two groups did not statistically differ significantly ( P = .31 and .09, respectively). Conclusions: VSLN is an effective treatment for lower extremity lymphedema. The types, numbers of veins, and techniques of venous anastomoses did not statistically affect the venous complication rates. Functional outcomes of the VSLNs were not compromised if venous complications were salvaged promptly.
