Lymphaticovenular anastomosis

Satoshi Onoda, Kiyoshi Yamada, Kumiko Matsumoto, Yoshihiro Kimata
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: The impact of lymphaticovenous anastomosis on lymphedema has yet to be defined. The authors investigated the clinical evidence regarding the effectiveness of lymphaticovenous anastomosis in lower limb lymphedema. METHODS: Eighty-four patients (162 limbs; 73 female and 11 male patients) with lower limb lymphedema who underwent multisite lymphaticovenous anastomosis in the authors' clinic between August of 2010 and May of 2014 were included in this retrospective study...

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...

OBJECTIVE: To investigate the therapeutic effect of modified side-to-end lymphaticovenular anastomosis in the treatment of post-mastectomy upper limb lymphedema. METHODS: Between May 2010 and May 2011, 11 female patients with post-mastectomy upper limb lymphedema underwent a modified side-to-end lymphaticovenular anastomosis. The average age was 49.5 years (range, 38-55 years). Lymphedema occurred at 7-30 months (mean, 18.3 months) after resection of breast cancer, with an average disease duration of 25...

BACKGROUND AND METHODS: Indocyanine green (ICG) lymphography is one of several methods of lymphography to detect lymphatic channels and evaluate patients clinically with limb lymphedema. ICG imaging is made possible by the use of a near-infrared camera device. The fluorescence images were digitalized for real-time display. RESULTS: ICG lymphography findings are largely classifiable into two patterns: normal linear pattern and abnormal dermal backflow (DB) pattern...

BACKGROUND: Collecting lymphatics have lymph-drainage function with contraction of smooth muscle cells. Patients with edema have lost this drainage function due to degeneration of smooth muscle cells. Lymphaticovenular (LV) anastomosis salvages smooth muscle cells from reversible degeneration (mild edema), but muscle cells cannot be recovered from irreversible degeneration (severe edema). Therefore, in severe edema, LV anastomoses cannot reestablish the drainage function of the lymphatic system...

INTRODUCTION: Lymphaticovenular anastomosis (LVA) has become an important procedure for the surgical treatment of lymphedema. In the past, the anatomy of the lymphatic system of animal models has been reported. However, to our knowledge, there have been few reports of animal models of LVA including training model. In this study, we report on a relatively simple and ideal animal LVA model based on peritoneal lymph ducts and veins. PATIENTS AND METHODS: For 10 rats, diameters of lumbar lymphatic ducts and iliolumbar veins in the peritoneal cavity on both sides were measured, and LVA was performed...

BACKGROUND: Supermicrosurgical lymphaticovenular anastomosis (LVA) is a promising treatment modality for lymphedema. However, its practice is restricted by the surgeon/equipment-related factors, and its effectiveness limited by technical constraints. We conducted a pilot study to evaluate the feasibility of a modified "octopus" LVA technique in addressing the above problems. METHOD: Nine consecutive lymphedema patients underwent LVA procedure using the "octopus" technique...

Lymphedema is a chronic progressive edematous disease that in the United States is most commonly related to malignancy and its treatment. Lymphaticovenular anastomosis is a recently introduced microsurgical treatment option for lymphedema that requires the identification and mapping of individual lymphatic channels. While nuclear medicine lymphoscintigraphy has been the primary imaging modality performed to evaluate suspected lymphedema, lymphoscintigraphy does not provide the spatial information necessary for presurgical planning...

BACKGROUND: Vascularized lymph node transfer has become a popular surgical option to improve lower extremity lymphedema (LEL), although potential donor sites are limited. The free supraclavicular flap with deep cervical lymph nodes has been recently associated with a minimal risk of secondary lymphedema caused by donor site dissection. However, the effectiveness of this procedure has not yet been evaluated. METHODS: Vascularized supraclavicular lymph node transfer (VSLNT) was performed for patients with International Society of Lymphology late stage II or more severe LEL...

BACKGROUND: Identification of lymphatic vessels for lymphaticovenular anastomosis (LVA), which is an effective surgical treatment for obstructive lymphedema, is important. Indocyanine green (ICG) lymphography is useful for that purpose, but is not common in many institutions. Although ultrasound is a very common modality, no research has yet underlined the feasibility of the device to detect the lymphatic vessels. METHODS: First, identification of lymphatic vessels in the lower legs using ultrasound was performed in non-edematous limbs with linear-pattern on ICG lymphography (n = 12)...

Lymphatic supermicrosurgery or supermicrosurgical lymphaticovenular anastomosis (LVA) is becoming popular for the treatment of compression-refractory upper extremity lymphedema (UEL) with its effectiveness and minimally invasiveness. In conventional LVA, superficial lymphatic vessels are used for anastomosis, but its treatment efficacy would be minimum when superficial lymphatic vessels are severely sclerotic. Theoretically, deep lymphatic vessels can be used for LVA, but no clinical case has been reported regarding deep lymphatic vessel-to-venous anastomosis (D-LVA)...

Microscope-integrated lymphangiography is a useful method in the field of lymphatic supermicrosurgery. Fluorescence based on indocyanine green (ICG) is the most commonly used. Fluorescein sodium is a fluorescent tracer used for retinal and neurosurgical angiography but not yet for lymphatic supermicrosurgery. In this report, we present a case in which the fluorescein sodium fluorescence microscope-integrated lymphangiography was used for assessment of lymphatic drainage pathway and patency in a patient treated for secondary lymphedema by lymphaticovenular anastomoses...

Background: Lymphaticovenular anastomosis (LVA) is becoming a choice of treatment for compression-refractory lymphedema. However, LVA requires highly sophisticated microsurgical technique called supermicrosurgery, and no training model for LVA has been developed. This study aimed to develop and evaluate feasibility of a new LVA model using rat thigh lymphatic vessels. Methods: Ten Sprague-Dawley rats were used for the study. After preoperative indocyanine green (ICG) lymphography, lymphatic vessels in posteromedial aspect of the thigh were dissected...

Supermicrosurgical lymphaticovenular anastomosis (LVA) has been reported to be useful for the treatment of obstructive lymphedema. However, LVA has a potential risk of anastomosis site thrombosis. It is more physiological to use a lymphatic vessel as a recipient vessel of lymphatic bypass surgery, because there is no chance for blood to contact the anastomosis site. We report a chronic localized lower leg lymphedema case treated with supermicrosurgical superficial-to-deep lymphaticolymphatic anastomosis (LLA)...

BACKGROUND: One of the complications of lymphoedema is recurrent cellulitis. The aim was to determine whether lymphaticovenous anastomosis (LVA) was effective at reducing cellulitis in patients with lymphoedema. METHODS: This was a retrospective review of patients with arm/leg lymphoedema who underwent LVA. The frequency of cellulitis was compared before and after surgery. The diagnostic criteria for cellulitis were a fever of 38·5°C or higher, and warmth/redness in the affected limb(s)...

BACKGROUND: Lymphorrhea can occur after surgical intervention to the lymphatic system. Most cases with lymphorrhea can be treated conservatively, but some cases are refractory to conservative treatments and require further surgical treatments. METHODS: Eight patients developed inguinal lymphorrhea after surgical intervention in the groin region. Navigation lymphatic supermicrosurgery (NLS) was performed for the treatment of iatrogenic lymphorrhea refractory to conservative treatments...
