Lymphaticovenular anastomosis for breast cancer-related upper extremity lymphedema: a literature review.

Breast cancer-related lymphedema is a long-term condition that affects almost half of breast cancer survivors. Clinical studies have looked at the benefits of lymphaticovenular anastomosis (LVA) for the treatment of upper extremities lymphedema after breast cancer, however, there is still controversy if it improves lymphedema. This study aimed to analyze the studies and outcomes related to LVA for breast cancer-related lymphedema. A PubMed/Medline search was performed using "lymphovenous bypass", "upper extremity lymphedema", "arm lymphedema after breast cancer treatment", and "lymphaticovenular anastomosis" as key words. Only English articles reporting outcomes after LVA were included. We found 22 articles that met the inclusion criteria. Positive outcomes were found in 21 studies with an objective volume reduction and subjective symptoms relief after LVA. This literature review concluded that LVA has demonstrated a significant decrease in upper extremity volumes and an improvement in subjectively reporting symptoms in breast cancer-related lymphedema patients. 2020 Gland Surgery.
