Abstract: Lymphatic malformation (LM) is a congenital malformation of lymphatic development in which a large amount of lymph fluids accumulating in the malformed and dilated lymphatic lumen of the lesions. When the lymphatic immune response of the patient is enhanced, the swelling and dysfunction of the lesion area will occur, which brings great pain to the patient. At present, the main treatment methods for LM include sclerotherapy, surgical resection, targeted drug therapy, etc. However, none of these treatment methods can achieve long-term recovery and reconstruction of abnormal lymphatic reflux in the lesion area. Lymphatic-venous anastomosis(LVA), as one of the representatives of supermicrosurgical techniques, can reconstruct the lymphatic vessels in the lesion area with the surrounding veins through lymphatic visualization and microscopy, so as to achieve the goal of improving and reconstructing the local lymphatic drainage. At present, some studies have attempted to perform such surgery in patients with LM and achieved good results, but it has not been widely promoted. Based on the latest research results both at home and abroad, this article reviewed lymphatic imaging technology, lymphatic imaging staging and classification of LM, surgical methods of LVA, research and application status of LVA in the treatment of LM, and perioperative nursing of LVA, in order to promote the research, application and development of this technology in the field of LM treatment.
