BACKGROUND:  Venules have been usually neglected in the literature on lymphaticovenular anastomosis (LVA). The aim of this study was to analyze the flow dynamic of recipient venules in LVA and their impact on the surgical outcomes. PATIENTS AND METHODS:  Data from 128 patients affected by extremity lymphedema, who underwent LVA, were collected in two institutions from August 2014 to May 2016. Recipient venules were classified according to their flow dynamic into backflow, slack, and outlet (BSO classification)...

BACKGROUND:  Lymphedema is a progressive disease that negatively affects body image and physical, psychological, and social functions. There is lack of evidence in the present literature about the impact of super microsurgical lymphaticovenular anastomosis (LVA) on health-related quality of life (HRQoL). The aim of this prospective study is to report the outcomes of patients' HRQoL after LVA for lower and upper extremities lymphedema. METHODS:  Between September 2015 and February 2017, 74 patients with upper or lower limb lymphedema (ULL or LLL) underwent LVA at our center...

Although a large number of treatments have been developed for lymphedema, definitive management still remains a challenge for plastic surgery, because not all surgical techniques have a positive effect on every patient, and good results are difficult to reproduce. However, it is important to recognize the efforts that Professor Isao Koshima and his colleagues together with the Government of Japan are carrying out to spread information to the different countries on the newest surgical techniques available in current plastic surgery and to motivate young doctors in developing countries to create a microsurgery unit in their home country, providing them with the necessary knowledge and skills to deliver real solutions to complex problems that were previously unanswered...

Background: Surgical treatment of lower extremity lymphedema (LEL) remains challenging. Application of the superior-edge-of-the-knee incision method for lymphaticovenular anastomosis (LVA) is reported to have a strong therapeutic effect in patients with LEL because lymph-to-venous flow at the anastomosis is enhanced by knee joint movement during normal walking. We investigated whether a single LVA created by this method is adequate for early LEL. Methods: The study involved 10 patients with LEL characterized by stage 2 or 3 leg dermal backflow and treated by a single LVA at the thigh via the superior-edge-of-the-knee incision method...

BACKGROUND: Lymphaticovenular anastomosis (LVA) has become one of the useful surgical treatments for compression-refractory lower extremity lymphedema (LEL). It is important to anastomose larger lymphatic vessels with abundant lymph flows in LVA surgery. This study aimed to clarify factors associated with lymphatic vessel diameter. METHODS: One hundred thirty-four LEL patients who underwent pre-operative indocyanine green (ICG) lymphography and LVA from June 2009 to August 2014 in a single institution were included in this retrospective observational study...

BACKGROUND: Identification of functional lymphatic vessels and localization of lymphatic vessels are important for lymphaticovenular anastomosis (LVA). Indocyanine green (ICG) lymphography is useful for localization of superficial lymphatic vessels where dermal backflow is not observed, but not for lymphatic vessels in deep layer or where dermal backflow is observed. Ultrasound has been applied in LVA and is considered useful for localization of lymphatic vessels with ICG lymphography cannot be visualized...

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...

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...
