Preoperative Indocyanine Green Lymphography and High-Frequency Ultrasound as Predictors of Lymphaticovenous Anastomosis Outcome in Post-Mastectomy Upper Limb Lymphedema
Egypt30 participantsStarted 2026-05-27
Plain-language summary
This study aims to evaluate the predictive value of preoperative indocyanine green (ICG) lymphography and high-frequency ultrasound in determining the outcomes of lymphaticovenous anastomosis (LVA) in patients with post-mastectomy upper limb lymphedema. Patients undergoing LVA surgery will undergo preoperative assessment using ICG lymphography and ultrasound mapping of lymphatic vessels and recipient veins. Surgical outcomes will be assessed clinically and functionally through limb circumference measurements, symptom improvement, and postoperative imaging findings. The study seeks to identify imaging predictors associated with successful LVA outcomes and improved postoperative recovery.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* • Female patients aged 18 to 75 years.
* Unilateral secondary upper limb lymphedema following mastectomy with axillary lymph node dissection.
* Minimum interval of six months from completion of oncological treatment (surgery, radiotherapy, systemic therapy) to enrollment.
* ISL clinical stage I or II at the time of enrollment; late stage II eligible if patent lymphatic vessels are identified on preoperative HFUS.
* Provision of written informed consent (prospective phase).
Exclusion Criteria:
* Bilateral upper limb lymphedema.
* Active locoregional or distant oncological recurrence.
* Prior lymphatic surgery on the affected limb.
* Severe peripheral vascular disease.
* Pregnancy or planned pregnancy during the study follow-up period.
* Documented hypersensitivity to indocyanine green or iodine
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
