Name of journal: The Annals of thoracic surgeryAbstract: BACKGROUND: When conservative therapy for thoracic outlet syndrome (TOS) fails, scalenectomy with or without first-rib resection(FRR) is the treatment of choice. We measured pressure in the costoclavicular space(CCS) before and after FRR at time of neurogenic TOS(NTOS) release to evaluate if FRR is required to completely decompress the CCS.CONCLUSIONS: First rib resection for management of NTOS can be safely performed with favorable outcomes. The pressure increase experienced in the CCS caused by arm abduction and external rotation was significantly reduced only post-FRR, raising concerns about potential incomplete CCS decompression with scalenectomy alone for NTOS management.

Pressures were recorded in both arm positions pre-scalenectomy, post-scalenectomy, and post-FRR. Paired t-test was used to compare differences in group means for paired samples. Patient-reported outcomes were reported using the Derkash classification and Quick Disabilities of the Arm, Shoulder, and Hand (qDASH) questionnaire.RESULTS: Fifteen patients(16 cases) surgically treated for NTOS were included in this retrospective study. There was no significant difference in pressure change between arm positions pre-scalenectomy(161.56 +/- 71.65 mmHg difference) or post-scalenectomy(148.5 +/- 80.24 mmHg difference). There was a significant difference in pressure change between arm positions when comparing post-scalenectomy and post-FRR; mean pressure change between arm positions post-FRR was 50.56 +/- 40.28 mmHg. Mean post-operative qDASH score was 20 +/- 23.2. All patients reported improvement in symptoms and functional status.All authors: Assi PE, Giladi AM, Hui-Chou HG, Segalman KAOriginally published: Annals of Thoracic Surgery. 2020 Feb 08Fiscal year: FY2021Fiscal year of original publication: FY2020Digital Object Identifier: Date added to catalog: 2020-02-26
