Initial treatment consists of decongestive physiotherapy. In case of poor stability, recurrent lymphangitis, and/or progression of lymphedema, surgical treatment should be considered. A valid surgical treatment option consists of micro-surgical lymphatic-venous anastomosis (MLVA). The current video displays the key surgical steps of MLVA, based on a specific case of cancer-related left lower limb lymphedema after RARP and LND. METHODS: The current video (produced in March 2023) reports the clinical case of a 58-year-old male patient diagnosed with cancer-related left lower limb lymphedema after 18 months from RARP and LND for prostate cancer (GS 4+3, pT3a-pN1, three positive nodes on total 11 removed nodes). Lymphedema-related symptoms consisted of cutaneous swelling, pain and deambulation difficulty. Superficial and deep lymphatic circulation was assessed with preoperatory lymphoscintigraphy, which revealed absence of lymphatic return from the left lower extremity. MLVA was performed under the left groin crease. Lymphatic vessels were visualized after injection of blue dye and indocyanine green at five sites from the internal to the anterior surface of the thigh, into the dermal, subcutaneous and epifascial areas. For the lymphatic-venous anastomosis, the operating microscope (10-15x) was used. The patency of the lymphatic afferent was confirmed based on leakage of lymph. The superficial external pundendal vein was isolated and prepared for the anastomosis. The dissection of the venous tunica avventitia was performed in order to reduce the risk of anastomotic stricture, potentially due to the vasa nervorum hypertone. Two lymphatic vessels were then dunked into the venous branch through a sleeve technique, and the anastomosis performed with an invaginating running suture with U-shaped 8/0 stitch. The patency of the MLVA was checked at the operating microscope based on passage of blue dye from the lymphatics into the vein. RESULTS: Operative time was 90 minutes, and no intra-operatory complication occurred. Post-operatory period was uneventful, and the patient was discharged in second post-operatory day. At four months after MLVA, the left lower limb lymphedema was consistently reduced, and lymphedema-related symptoms were controlled. CONCLUSIONS: Lower limb lymphedema may affect a non-negligible rate of patients treated with RARP and LND for prostate cancer. An effective treatment, in case of unresponsiveness to conservative therapy, consists of micro-surgical lymphatic-venous anastomosis. This is an ultra-specialistic surgery, which demands referral to high-volume and high-expertise centres.
