Blood Flow Changes in Subsynovial Connective Tissue on Contrast‐Enhanced Ultrasonography in Patients With Carpal Tunnel Syndrome Before and After Surgical Decompression

Although qualitative alteration of the subsynovial connective tissue in the carpal tunnel is considered to be one of the most important factors in the pathophysiologic mechanisms of carpal tunnel syndrome (CTS), little information is available about the microcirculation in the subsynovial connective tissue in patients with CTS. The aims of this study were to use contrast-enhanced ultrasonography (US) to evaluate blood flow in the subsynovial...
