Considerations for Surgical Treatment of Neurogenic Thoracic Outlet Syndrome: A Meta-Analysis of Patient-Reported...

It remains unclear whether first rib resection (FRR), performed via a supraclavicular (SCFRR) or transaxillary (TAFRR) approach, is necessary for patients with neurogenic thoracic outlet syndrome (nTOS). In a systematic review and meta-analysis, we performed a direct comparison of patient-reported functional outcomes following different surgical approaches for nTOS.

The authors searched PubMed, Embase, Web of Science, Cochrane Library, PROSPERO, Google Scholar, and the gray literature. Data were extracted based on the procedure type. Well-validated patient-reported outcome measures were analyzed in separate time intervals. Random-effects meta-analysis and descriptive statistics were used where appropriate.

Twenty-two articles were included, with 11 discussing SCFRR (812 patients), 6 discussing TAFRR (478 patients), and 5 discussing rib-sparing scalenectomy (RSS; 720 patients). The mean difference between preoperative and postoperative Disabilities of the Arm, Shoulder and Hand score was significantly different comparing RSS (43.0), TAFRR (26.8), and SCFRR (21.8). The mean difference between preoperative and postoperative visual analog scale scores was significantly higher for TAFRR (5.3) compared to SCFRR (3.0). Derkash scores were significantly worse for TAFRR compared to RSS or SCFRR. RSS had a success rate of 97.4% based on Derkash score, followed by SCFRR and TAFRR at 93.2% and 87.9%, respectively. RSS had a lower complication rate compared to SCFRR and TAFRR. There was a difference in complication rates: 8.7%, 14.5%, and 3.6% for SCFRR, TAFRR, and RSS, respectively.

Mean differences in Disabilities of the Arm, Shoulder and Hand scores and Derkash scores were significantly better for RSS. Higher complication rates were reported after FRR. Our findings suggest that RSS is an effective option for the treatment of nTOS.
