Official title

Early Feasibility Study on Intraoperative Parathyroid Gland (PTG) Identification Using a Hand-Held Imager (HHI)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

It is often challenging to tell apart the parathyroid glands from the surrounding area such as lymph nodes, fat and thyroid tissue. If the surgeons are not able to tell where the parathyroid glands are, they might accidentally be removed or damaged. This can lead to complications such as hypocalcemia (low calcium level) requiring treatment and sometimes lead to longer hospital stay. This study is designed to test a new method (a non-invasive hand-held imaging device) to assist surgeons in identifying the parathyroid glands, in order to decrease the rate of post-operative complication.
