The benefict of near-infrared for lymphatic surgery
Lymphedema is a chronic peripheral swelling caused by a dysfunction of the lymphatic system, leading to discomfort and loss of upper limb movement. Therapies to treat or manage this swelling have limited evidence, partly because of a paucity in objective lymphatic measures. This study explored the role of near-infrared (NIR) imaging in evaluating interventions.
Vascularized lymph node transfer as a surgical treatment
Vascularized lymph node transfer (VLNT) as a surgical treatment for cancer-related lymphedema has shown beneficial effects. The mechanism of action of this procedure involves lymphangiogenesis and lymphovenous communications (LVC) within the lymph nodes.
The use of near-infrared imaging for parathyroid surgery
Parathyroid glands (PGs) can be particularly hard to distinguish from surrounding tissue and thus can be damaged or removed during thyroidectomy. Postoperative hypoparathyroidism is the most common complication after thyroidectomy. Very recently, it has been found that the parathyroid tissue shows near-infrared (NIR) auto-fluorescence which could be used for intraoperative detection, without any use of contrast agents.
Identification of autofluorescent parathyroid glands
Identification of parathyroid glands may be challenging during thyroid and parathyroid surgery. Accidental resection of the glands may increase the morbidity of the surgery. The aim of this study was to evaluate accuracy in identification of autofluorescent parathyroid glands with the use of near infrared light in real time.
Indocyanine green fluorescence and parathyroid autofluorescence
Indocyanine green fluorescence (ICGF) and parathyroid autofluorescence (AF) are two new techniques that aid in the identification of parathyroid glands (PG) intraoperatively during thyroidectomy. There is no study comparing the efficacy of these techniques.
Indocyanine green advantages for the detection of free-flap vascular complications
We evaluated the feasibility and the tolerance of repeated fluorescent indocyanine green angiography in free flap monitoring, and determined the intraoperative predictive values of flap vitality.
L’angiographie par fluorescence pour le suivi des lambeaux perforants
Reconstructive surgery has for objective to restore anatomical defects using flaps. We tested fluorescent angiography in reconstructive surgery using the Fluobeam™ device for flap planning and monitoring.
Dermal lymphatic function and pressure ulcers
It is proposed that direct mechanical loading can impair dermal lymphatic function, contributing to the causal pathway of pressure ulcers. The present study aims to investigate the effects of loading on human dermal lymphatic vessels. Ten participants were recruited with ages ranging from 24 to 61 years.
Utilisation de la fluorescence lymphographie pour la fonction lymphatique
Impaired lymph formation and clearance has previously been proposed as a contributory factor in the development of pressure ulcers. The present study has been designed to trial fluorescence lymphangiography for establishing how lymphatic function is altered under a clinically relevant form of mechanical loading.
Fluorescence tracer imaging or radioguided technique for sentinel node biopsy
Sentinel node biopsy (SNB) is an established method in oral squamous cell carcinoma (OSCC) for staging the cN0 neck and to select patients who will benefit from a neck dissection. Near-infrared fluorescence (NIRF) imaging has the potential to improve the SNB procedure by facilitating intraoperative visual identification of the sentinel lymph node (SN).
