The primary aim of this study is to investigate and test whether the use of combined indocyanine green (ICG) lymphography and ultra high frequency ultrasonography can correctly identify lymphatic vessels and venoles in close proximity to each other, for identification prior to lymphovenous anastomosis (LVA) surgery.
BACKGROUND
Breast-cancer related lymphedema is a life-disabling side-effect of breast cancer treatment, affecting more than 1 in every 5 patients. With breast-cancer being the most common cancer diagnosis in women, affecting up to 2.3 million new cases globally, and with a generally high survival rate of 80% or higher in developed countries, the number of breast-cancer survivors with long-term sequela is significant. Compression garments have been considered the standard treatment and rehabilitation for lymphedema. Some of the disadvantages with these treatments include variability in patient compliance, clinical effect and lack of statistical significant results. Therefore, the rehabilitation and treatment options for lymphedema are in high demand, affecting patients physical and mental health.
Lymphovenous anastomosis (LVA) surgery is an attempt to re-establish the lymphatic flow, utilizing the patient's own lymphatic- and venous vessels. Surgical treatment seems effective in selective patient groups, but systematic studies for this are lacking. It is based on this lack of knowledge of patient characteristics and preoperative planning that the project's hypothesis and idea was formed.
Indocyanine green (ICG) lymphography is commonly used for identification of lymphatic vessels pre-operatively, and is considered superior to other modalities. However, until recently, the identification of adjacent venoles has remained a challenge. Ultra high frequency ultrasound may have solved the challenge of identifying the small venoles prior to surgery. The combined use of ICG lymphography and ultra high frequency ultrasound may be the key to optimise patient selection and pre-operative planning of lymphovenous anastomosis surgery.
METHOD
This study is designed as a pilot study with a planned inclusion of 10 patients with a 3 months follow-up period.
The inclusion of patients, the surgical procedure and 3 months follow-up evaluation will take place at the Department of Plastic Surgery Odense University Hospital (OUH), Denmark.
The ICG lymphography is performed by injecting ICG subcutaneously, and used for visualization of the superficial lymphatics for preoperative planning. During real-time visualization, lymphatic vessels are drawn up on the patients arm using a permanent marker.
Ultra high frequency ultrasound (>30MHz) has the ability to visualize small, superficial anatomical layers. Using this ultra high frequency ultrasound (70MHz), following the mapped lymphatic vessels, venous vessels are found nearby and likewise mapped for anastomosis.
The number of LVA anastomosis sites is set to a minimum of two sites per extremity. The number of mapped lymphatics vessels and venoles are compared to the number identified during surgery and recorded.
Prior to and 3 months after surgery, patients are seen for objective measures of upper extremity volume, body composition, L-Dex score of the affected arm and health-related quality-of-life, in addition to ICG lymphography.

| Changes in L-Dex score | L-Dex score is a measurement of extracellular fluid of the arm. A stand-on bioimpedance device, estimates the extracellular fluid trough electric impulses between its electrodes. Based upon the impedance ratio of the affected and unaffected arm, the bioimpedance calculates a Lymphedema index, called L-Dex ratio score. A number between -10 and 10 is considered normal, and diagnostic for lymphedema if above 10. Its sensitivity and specificity are 0.66 and 0.99, respectively, at a receiver operating characteristic curve (ROC) value of 10. The score correlates with the limb volume and lymphatic function. | Baseline and 3 months follow-up |
| Changes in health-related quality-of-life measured by the LYMPH-Q questionnaire | The LYMPH-Q Upper extremity module questionnaire is a validated patient-reported outcome tool for women with breast cancer related lymphedema. The module contains seven individual scales, measuring: symptoms, function, appearance, psychological function, and satisfaction with information on lymphedema and satisfaction with arm sleeve. Each scale gives an independent score reaching from 0 (worst) to 100 (best), which can be used for comparison of change over time. A higher score indicates a better outcome. Patients will complete the questionnaire at baseline and 3 months follow-up. | Baseline and 3 months follow-up |
| Changes of lymphatic flow pattern before and after surgery by ICG lymphangiography | Video recordings of ICG lymphographies are stored for later classification of the lymphedema. Staging will be done using the MD Anderson scale; a classification system based upon pattern recognition of the dermal backflow from the ICG lymphography, see table 1. MD Anderson stage ICG lymphography findings Stage 0 No dermal backflow Stage 1 Many patent lymphatics and minimal dermal backflow Stage 2 Moderate number of patent lymphatics and segmental dermal backflow Stage 3 Few patent lymphatics with extensive dermal backflow Stage 4 Dermal backflow involving the hand Stage 5 ICG does not move proximally to injection site Table 1: MD Anderson classification based upon ICG lymphography findings. | Baseline and 3 months follow-up |
