Long-term outcomes of transaxillary versus video-assisted first rib resection for neurogenic thoracic outlet syndrome

Abstract

OBJECTIVES: This study compared the long-term outcomes in terms of clinical examinations and patient-reported outcome measures, between transaxillary and video-assisted thoracoscopic techniques for first rib resection in patients with neurogenic thoracic outlet syndrome. METHODS: The study population comprised patients who underwent first rib resection for neurogenic thoracic outlet syndrome at our institution between 2009 and 2016. All patients were recruited in a follow-up assessment in 2019, and those who agreed to participate were included in this study. Outcomes included examinations at the outpatient clinic and patient-reported outcome measures: Disabilities of Arm Shoulder and Hand Score and Cervical Brachial Symptom Questionnaire. The completeness of the rib resection was assessed on chest X-rays. RESULTS:: A total of 60 first rib resections (30 transaxillary + 30 video-assisted fully thoracoscopic approaches) were performed for neurogenic thoracic outlet syndrome in 47 patients between 2009 and 2016. Of these, 32 patients participated in the study including 18 who had transaxillary and 22 who had video-assisted thoracoscopic procedures. The mean follow-up was 5.9 (standard deviation: 2.2) years. The outcome was good or excellent after 15 (83.3%) and 17 (77.3%) procedures in the transaxillary and video-assisted thoracoscopic surgery groups, respectively (P = 0.709). There were no differences in patient-reported outcome measures between the 2 groups. Furthermore, the length of the residual first rib stump was similar in both groups. CONCLUSIONS: We found no differences in the long-term outcomes between the study groups. These results indicate that both transaxillary and purely thoracoscopic approaches offer favourable long-term outcomes following first rib resection in patients with neurogenic thoracic outlet syndrome.
