Assessment of Lymphaticovenous Drainage Through Vascularized Lymph Node Flaps Using Real-Time High-Resolution Fluorescent Imaging.
نویسندگان
چکیده
PURPOSE: Vascularized lymph node (VLN) transfer is a promising treatment option for patients suffering from lymphedema. Despite positive preliminary outcomes, several questions remain unanswered, including mechanism of action and optimal flap design. The purpose of this study was to: 1) evaluate the mechanism of lymph drainage through the VLN flap, and 2) investigate if the number of VLNs impacts lymph transit time through the flap.

Vascularized groin lymph node transfer using the wrist as a recipient site for management of postmastectomy upper extremity lymphedema.
BACKGROUND Restoring the continuity of lymphatic drainage by lymphaticovenous or lymphaticolymphatic anastomosis was observed in the short term to be patent but eventually occluded because the elevated interstitial pressure will cause obliteration of these tiny, thin-walled, low-pressure lumens. The purpose of this study was to evaluate the outcome of vascularized groin lymph node transfer usin...

Lymphedema is a condition characterized by tissue swelling caused by localized fluid retention. Advanced lymphedema is characterized by irreversible skin fibrosis (stage IIIb) and nonpitting edema, with leather-like skin, skin crypts, and ulcers with or without involvement of the toes (stage IVa and IVb, respectively). Recently, surgical treatment of advanced lymphedema has been a challenging r...

متن کاملQuantity of lymph nodes correlates with improvement in lymphatic drainage in treatment of hind limb lymphedema with lymph node flap transfer in rats.
PURPOSE This study was conducted to investigate the correlation between the number of vascularized lymph nodes (LN) transferred and resolution of hind limb lymphedema in a rat model. METHODS Unilateral hind limb lymphedema was created in 18 male Sprague-Dawley rats following inguinal and popliteal LN resection and radiation. A para-aortic LN flap based on the celiac artery was subsequently tr...
