Near-infrared Imaging Techniques for Identifying and Preserving Viable Parathyroid Glands During Thyroidectomy
Denmark155 participantsStarted 2021-10-01
Plain-language summary
The parathyroid glands and their blood vessels are notoriously difficult to visualize and may therefore be unintentionally and irrevocably damaged during thyroid surgery. This project investigates new surgeon-performed imaging techniques that visualize the parathyroid glands and their vessels in real-time during thyroid surgery. The purpose is to examine, in a matched cohort study, whether the implementation of near-infrared-induced autofluorescence for identification of the parathyroid glands, combined with indocyanine green near-infrared angiography of the parathyroid feeding vessels, can reduce the incidence of postoperative hypocalcaemia in patients undergoing total and completion thyroidectomy at Odense University Hospital.

Exclusion Criteria:
* Not legally competent.
* Does not read or speak Danish.
* Is pregnant or nursing.
* Suffers from chronic kidney disease with an estimated glomerular filtration rate \< 45 ml/min/1.73m2.
* Has a history of allergy to iodides or to indocyanine green.
* Suffers from hyperparathyroidism, hypoparathyroidism, or hypocalcaemia prior to surgery.
* Prescription use of supplemental active vitamin D: dihydrotachysterol (ATC 11CC02), alfacalcidol (ATC A11CC03), or calcitriol (ATC A11CC04).
* Patients scheduled to have a radioactive iodine uptake study performed ≤ 7 days after the thyroidectomy.
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.
