Concordance for Transthyretin Amyloidosis Between Synovial Biopsy and Anterior Carpal Ligament Biopsy (ATTR2026)
Assessment of Diagnostic Concordance for Transthyretin Amyloidosis Between Synovial Biopsy and Anterior Carpal Ligament Biopsy in Patients Who Underwent Endoscopic Carpal Tunnel Syndrome Surgery
Transthyretin amyloidosis (ATTR) is an underdiagnosed condition that can present early as carpal tunnel syndrome, sometimes preceding cardiac involvement by several years. The recent emergence of new treatments underscores the importance of early diagnosis. Synovial biopsy performed during open carpal tunnel surgery is considered the gold standard for local screening, but it is less accessible, more difficult, and riskier to perform via endoscopy-a minimally invasive surgical technique that is currently the standard at our center and is becoming increasingly widespread.
The anterior annular ligament of the carpus constitutes an alternative tissue to the synovium, easily accessible via endoscopy, safe, and standardizable.
In this study, the systematic performance of an annular ligament biopsy in conjunction with a synovial biopsy during endoscopic carpal tunnel surgery would allow for the evaluation of the diagnostic concordance of the ligament biopsy by comparing it to the results obtained using the gold standard method. This strategy would also provide an opportunity to analyze the feasibility of systematic screening for ATTR on the ligament during endoscopic procedures.
This approach could offer a practical and innovative method for the early identification of at-risk patients and facilitate appropriate and timely management of the condition.

|
To evaluate and describe the feasibility of routinely performing a biopsy of the anterior annular ligament of the carpus during endoscopic carpal tunnel surgery.
Feasibility will be assessed by the proportion of procedures in which a biopsy specimen of the anterior annular ligament of the carpus can be successfully obtained and submitted for histopathological analysis during endoscopic carpal tunnel surgery.
