The Dynamic Lymphaticovenular Anastomosis for Breast Cancer–related Lymphedema without Compression: Salvaging Lymphedema Patients Who Lost Conservative Treatment Opportunity

In conservative treatment for breast cancer–related lymphedema (BCRL), compression therapy has a crucial role. However, some BCRL patients are unable to use compression, and then their lymphedema continues to worsen as they miss treatment opportunity. Although lymphaticovenular anastomosis (LVA) is an effective and minimally invasive surgical treatment for BCRL, compression therapy is still important to enhance lymphatic fluid flow in LVA. The authors previously reported the dynamic LVA method for BCRL, in which patient's natural hand movements theoretically propel lymph to the anastomosed vein. This study is conducted to clarify whether dynamic LVA can salvage BCRL patients without pre- and postoperative compression therapy. METHODS: The study involved 17 BCRL patients, 18 limbs. All patients had International Society of Lymphology stage-2 lymphedema, but they had no compression: six patients had difficulty by other diseases to undergo compression, and other 11 patients refused any compression usage because of the burden of the treatment itself. Three dynamic LVAs were performed in each patient. RESULTS: Patients’ mean age was 60.4 ± 10.1, and mean body mass index was 24.0 ± 3.3. The mean follow-up period was 25.5 ± 9.2 months. The volume of the lymphedematous limb, according to the upper extremity lymphedema (UEL) index, was reduced in all 18 limbs postoperatively (postoperative UEL index 101.8 ± 9.4 versus preoperative UEL index 116.0 ± 20.1; P < 0.01). Twelve of the 18 limbs were cured without edema. CONCLUSION: Even without compression therapy, International Society of Lymphology stage-2 BCRL patients can be treated by the dynamic LVA method.
