BACKGROUND: Following vascularized lymph node (VLN) transfer (VLNT), the VLN may be at a risk for sclerosis because of efferent lymphatic vessel obstruction. We developed a new technique to prevent VLN sclerosis via a prefabricated lympho-venous (LV) shunt. This study compared the treatment outcomes of single VLNT with prefabricated LV shunt, conventional multiple VLNTs, and conventional single VLNT. METHODS: Overall, 47 limbs of 45 patients that underwent VLNT for lower-extremity lymphedema (LEL) in late clinical stage II/III were divided into 3 groups: conventional single VLNT group (control; 21 limbs where 4 had primary LEL), multiple VLNTs group (13 limbs where 3 had primary LEL), and prefabricated LV shunt group (13 limbs where 4 had primary LEL)...

BACKGROUND: Patients with secondary lower extremity lymphedema (LEL) often develop suprapubic lymphedema. We developed a novel surgical method of shaping the lower abdomen and debulking suprapubic lymphedema with simultaneous reconstruction of lymphatic flow in case of LEL. METHODS: A skin incision in a fleur-de-lis pattern was performed for horizontal and vertical abdominal skin and fat resection. A caudal-based isosceles triangular flap was created on the central suprapubic region to reduce wound tension at the intersection of the horizontal and vertical incisions...

PURPOSE: Despite extensive previous investigations regarding the efficacy of lymphaticovenular anastomosis (LVA) for the treatment of lymphedema, few studies have reported the long-term clinical course of individual patients undergoing LVA. The present study presented our experience of LVA and to report serial postoperative courses. METHODS: A retrospective chart review was performed for 17 patients (2 male and 15 female) with lymphedema refractory to conservative treatment who underwent LVA and were followed-up for at least postoperative 24 months...

Secondary lymphedema of the upper and lower extremities related to prior oncologic therapies, including cancer surgeries, radiation therapy, and chemotherapy, is a major cause of long-term morbidity in cancer patients. For the upper extremities, it is most commonly associated with prior oncologic therapies for breast cancer, while for the lower extremities, it is most commonly associated with oncologic therapies for gynecologic cancers, urologic cancers, melanoma, and lymphoma. Both non-surgical and surgical management strategies have been developed and utilized, with the primary goal of all management strategies being volume reduction of the affected extremity, improvement in patient symptomology, and the reduction/elimination of resultant extremity-related morbidities, including recurrent infections...

BACKGROUND: Lymphaticovenular anastomosis is a useful treatment option for compression-refractory lower extremity lymphedema, but its efficacy depends largely on the severity of lymphosclerosis. To maximize lymphaticovenular anastomosis efficacy, it is important to elucidate factors associated with severe lymphosclerosis. METHODS: Medical charts of 134 lower extremity lymphedema patients who underwent preoperative indocyanine green lymphography and lymphaticovenular anastomosis were reviewed to obtain data of clinical demographics, indocyanine green lymphography findings, and intraoperative findings...

INTRODUCTION: Lymphedema can be a debilitating condition, causing a great decrease in a person's quality of life (QoL). Treatment with lymphaticovenular anastomosis (LVA), in which an anastomosis is created between the lymphatic and venous system, may attenuate lymphedema symptoms and reduce swelling. In this study, we share the results using LVA to treat breast cancer-related lymphedema (BCRL) at our institution. MATERIALS AND METHODS: Patients were eligible for inclusion if they suffered from unilateral BCRL, if functional lymphatics were available, if compression therapy was used for at least 6 months, and if the follow-up was 12 months at minimum...

BACKGROUND: Lymphaticovenular anastomosis (LVA) is a supermicrosurgical procedure that involves the anastomosis of a functional lymphatic channel to a venule. Although peri-operative care might be an important contributor to the success of this technique, evidence about optimal peri-operative care seems limited. This review aims to summarize the peri-operative methods used by authors reporting on LVA. METHODS: A systematic search of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines...

OBJECTIVE: Lymphoedema of the extremities is a widespread pathological condition that mostly occurs as a complication of cancer resections, especially in women. Conventional therapy refers to conservative and physiotherapeutic approaches. Surgical strategies have been widely reported in the literature and are still challenging. Part of this literature focuses on the supra microsurgical lymphaticovenular anastomosis (LVA) technique. LVA is characterized by a high success rate, minimal invasivity and broad indications...

Background To date, only a few reports have been published on idiopathic lymphedema, and most of these are case reports. In this time, we performed a retrospective review of idiopathic lymphedema patients. Methods Forty patients presented with idiopathic lymphedema that was unrelated to surgery, injury, and medical conditions such as circulatory disease, kidney disease, and thrombotic venous disease. For these patients, we performed a retrospective review for edema-onset age, sex, location and stage of the edema, presence of cellulitis, episode related to edema onset, therapeutic intervention, and follow-up duration in the 33 patients whom we followed up...

Background Microsurgical vascularized lymph node transfer (VLNT) and supermicrosurgical lymphaticovenular anastomosis (LVA) are increasingly performed to treat lymphedema. The surgical outcome is commonly assessed by volume-based measurement (VBM), a method that is not consistently reliable. We describe indocyanine green (ICG) lymphography as an alternative postoperative tracking modality after lymphatic reconstruction with VLNT and LVA. Methods VLNT and LVA were performed in patients with therapy-refractory lymphedema...

BACKGROUND: Lymphaticovenular anastomosis plays an important role in the surgical treatment of lymphedema. The outcomes of lymphaticovenular anastomosis are evaluated based on changes in edema; however, isolated assessment of the anastomosis itself is difficult. The authors used an animal experimental model to conduct a detailed examination of histologic changes associated with lymphaticovenular anastomosis and determined the factors important for success. METHODS: The experimental lymphaticovenular anastomosis model was created using lumbar lymph ducts and iliolumbar veins of Wistar rats...

BACKGROUND: Lymphaticovenular anastomosis (LVA) is becoming a treatment option for lymphedema. It is challenging to perform LVA when a lymphatic vessel is too far from a vein to anastomose directly. METHODS: We applied vein grafting for simultaneous multisite LVA (SM-LVA), when there was a considerable distance between a lymphatic vessel and a vein. Five patients with lower extremity lymphedema (LEL) who underwent SM-LVA were included in this study. Feasibility and treatment effect of the method were evaluated...

BACKGROUND: Lymphatic vessel diameter and lymph flow are important for accurate anastomosis and effective lymph-to-venous flow in lymphaticovenular anastomosis. The authors developed a reliable method, the superioredge-of-the-knee incision method, for detecting and making the best use of high-flow lymphatic vessels in the distal medial thigh between the deep and superficial fascia, where movement of the knee, combined with compression between these fascial layers, theoretically results in upward propulsion of lymphatic fluid...
