Carpal tunnel release surgery for patients at risk of amyloidosis

Prospective Histopathologic and Clinical Evaluation of Patients Undergoing Carpal Tunnel Release With Risk Markers for Amyloidosis

Not applicable Interventional Henry Ford Health System · NCT05793320

This study is testing if patients with carpal tunnel syndrome have signs of amyloidosis by taking tissue samples during surgery to see if they need further heart checks.

What this trial studies

This study investigates the relationship between bilateral carpal tunnel syndrome and amyloidosis by performing tissue biopsies during carpal tunnel release surgery. Patients with bilateral symptoms will be identified and undergo biopsy for congo red staining to check for amyloid presence. Those with positive biopsy results will be referred to cardiology for further evaluation of potential cardiac amyloidosis. The study aims to assess the rate of amyloid positivity and common subtypes, as well as echocardiographic findings post-referral.

Who should consider this trial

Good fit: Ideal candidates include males over 50 and females over 60 with bilateral carpal tunnel symptoms or a history of related surgeries.

Not a fit: Patients who have previously been diagnosed with cardiac amyloidosis will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier diagnosis and management of cardiac amyloidosis in patients with carpal tunnel syndrome.

How similar studies have performed: While previous studies have explored the connection between carpal tunnel syndrome and amyloidosis, this specific approach of early referral based on biopsy results is novel.
