Abstract


Lymphatic complications following great and small saphenous vein surgery show a varying and non-negligible incidence in the literature. We undertook this study to investigate a new protocol to reduce lymphatic injuries in patients undergoing venous surgery. Eighty-six patients with lower limb venous insufficiency and varices were treated. Lymphoscintigraphy was performed preoperatively in 65 of them and postoperatively in 19. Blue dye was used in all patients and blue lymph nodes and lymphatics were identified intra-operatively and preserved or used to perform multiple lymphatic-venous anastomoses (MLVA). Patients were followed up for a period varying from 3 months to 6 years. Sixty-six patients were treated by greater saphenectomy and varicectomy, 12 patients had crossectomy and varicectomy, 4 patients underwent greater saphenectomy and varicectomy associated with MLVA, and 4 patients were treated by small saphenous vein stripping and varicectomy. No lymphatic complications occurred in any of the patients. A decrease of over 75% of excess volume was observed in 4 patients treated by MLVA. Lymphoscintigraphy showed normalization in the Transport Index in 4 patients treated with MLVA. Our results demonstrate that accurate diagnostic investigation and proper surgical technique is of paramount importance in the effort to avoid lymphatic complications during venous surgery.
