Clinical Context
A typical patient is an adult with chronic, limb-threatening lymphedema of a single upper or lower extremity refractory to conservative therapy (compression, manual lymphatic drainage, and physical therapy). The patient presents with progressive swelling, recurrent cellulitis, activity limitations, and quality-of-life impairment despite conservative measures for 6–12 months. Preoperative workup includes history and physical exam, limb volume measurements or perometry, duplex ultrasonography to exclude deep venous thrombosis, lymphoscintigraphy or indocyanine green (ICG) lymphography to map functional lymphatic channels, and routine preoperative labs. The surgical workflow includes preoperative mapping, general or regional anesthesia, incision and microsurgical dissection to identify lymphatic vessels and adjacent veins in the affected arm or leg, performance of lymphaticovenous anastomosis(s) to restore drainage, possible use of robotic assistance if available, intraoperative assessment of anastomotic patency (fluorescence or dye), wound closure, and postoperative plan with limb elevation, pulse compression and staged rehabilitation. Follow-up includes surveillance for patency, wound healing, and functional outcome assessments. Typical site of service is an outpatient surgical center or hospital operating room with microsurgical capabilities; observation or short inpatient stay may be required for higher-risk patients or complex reconstructions.
