Of 875 idiopathic carpal tunnel syndrome (CTS) cases, 101 (11.5%) required trigger digit release operations within three years before and/or after carpal tunnel release (CTR); these 101 cases were investigated, retrospectively. Trigger digit release (TDR) was performed most often after the CTR, especially within three months. Next most common was at the same time as the CTR. The TDR performance rate after CTR was 5.9%. The nerve conduction study (NCS) comparison between trigger digits-associated CTS and isolated CTS showed that pre-operative distal motor latency was significantly more delayed in trigger digits-associated CTS, while there was no evidence of any difference due to age or gender. The difference of operative method (open or endoscopic procedure) did not influence the incidence rate of trigger digits after the CTR. This study suggested that trigger digits-associated CTS has a previously developed wide-ranging narrowing of the flexor tendon sheath.

Purpose: Tunneled central venous catheter (tCVC) placement plays an important role in the management of pediatric patients. We adopted a real-time ultrasound (US)-guided supraclavicular approach to brachiocephalic vein cannulation. We evaluated the outcomes of tCVC placement via a US-guided supraclavicular approach. Methods: A retrospective study was performed for patients who underwent US-guided central venous catheterization of the internal jugular vein (IJV group) and brachiocephalic vein (BCV group) in our institution. The background information and outcomes were reviewed using medical records. Results: We evaluated 85 tCVC placements (IJV group: n = 59, BCV group: n = 26). Postoperative complications were recognized in 19 patients in the IJV group (catheter-related bloodstream infection (CRBSI), n = 14 (1.53 per 1000 catheter days); occlusion, n = 1 (1.7%, 1.09 per 1000 catheter days); accidental removal, n = 3 (5.2%, 0.33 per 1000 catheter days); and other, n = 1 (1.7%, 1.09 per 1000 catheter days)) and five patients in the BCV group (CRBSI, n = 2 (0.33 per 1000 catheter days); catheter damage, n = 1 (3.8%, 1.67 per 1000 catheter days); and accidental removal, n = 2 (7.7%, 0.33 per 1000 catheter days)). In the BCV group, despite that, the incidence of postoperative complications was lower ( p = 0.205) and the period of placement was significantly longer in comparison to the IJV group ( p = 0.024). Conclusion: US-guided placement of tunneled CVC though the BCV results in a low rate of postoperative complications despite longer CVC indwelling times compared to IJV insertion. Our results suggest that BCV insertion of tunneled CVC in children may offer advantages in terms of device performance and patient safety.
