Adverse events

Assessing Benefits of NIRAF Detection for Identifying Parathyroid Glands During Total Thyroidectomy. · Source last updated 2024-10-17

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Adverse events occurred during the study; they are not necessarily caused by treatment. Serious events are not interchangeable with severe/grade 3–4 events. These safety populations may differ from efficacy populations.

Collection time frame
Adverse event data was collected for 2 years and 5 months.

Parathyroid gland identification will be performed with PTeye using NIRAF detection technology as an adjunctive tool in patients who undergo total thyroidectomy (TTx) with or without lymph node dissection (LND). NIRAF Detection Technology: Near Infrared Autofluorescence (NIRAF) detection technology or 'PTeye' consists of a disposable fiber-optic probe that emits non-ionizing radiation from a NIR 785 nm laser source, and also transmits the resulting tissue NIRAF to a photo detector. The 785 nm laser source emits a maximum power of 20 mW. The device is FDA cleared for clinical use in general surgeries and dermatological use (Class 2 device). After surgeon identifies a potential parathyroid gland in the surgical field, the surgeon places the fiber-optic probe of PTeye on suspect tissue and presses the device foot-pedal to activate tissue NIRAF measurement. Auditory beep at high frequency with a Detection Ratio \> 1.2 is interpreted by device as the suspect tissue being positive for parathyroid.

Parathyroid gland identification will be performed with the naked eye of the surgeon without using PTeye - NIRAF detection technology in patients who undergo total thyroidectomy (TTx) with or without lymph node dissection (LND).
