ObjectiveAlthough the supraclavicular approach has been widely adopted for cervical rib resection, a transaxillary approach has been favored by many. We have reviewed more than two decades of experience with decompression of the thoracic outlet to treat thoracic outlet syndrome (TOS) in patients with complete cervical ribs using a novel transaxillary approach.MethodsA prospectively maintained database of patients undergoing surgery for TOS was searched for patients with complete (class 3 and 4) cervical ribs from 1997 to 2019. All these patients had undergone transaxillary resection using a technique in which the cervical and first ribs were separated and then individually resected. The data abstracted included patient demographics, symptoms, surgical details, and complications. The outcomes were contemporaneously assessed clinically and using standardized functional tools: somatic pain scale (SPS) and Quick Disabilities of the Arm, Hand, and Shoulder questionnaire (QuickDASH). The cervical rib data were organized and reported in accordance with the Society for Vascular Surgery reporting standards.ResultsDuring the study period, 1506 patients had undergone surgery for TOS at our institution. Of these 1506 patients, 38 had undergone complete transaxillary resection of 40 fully formed cervical ribs (10 class 3 and 30 class 4). Of these 38 patients, 74% were women. The presentations had been neurogenic (65%), arterial (31%), and venous (5%). The average initial SPS and QuickDASH score was 6.4 and 50, respectively. The duration of surgery averaged 141 minutes, blood loss was 65 mL, and length of stay was 2.1 days. None of the patients had experienced brachial plexus, phrenic, or long thoracic nerve injury. The average follow-up period was 65 months. The final mean postoperative SPS and QuickDASH scores were lower than the scores at presentation (SPS score, 6.4 vs 1.2; P < .001; QuickDASH score, 50 vs 17; P < .001).ConclusionsTo the best of our knowledge, the present study is the largest reported experience of resection of fully formed cervical ribs using a transaxillary approach that allowed for individual dissection and removal of cervical and first rib segments. This technique has proved to be successful, with low morbidity and reliable improvement in patient symptom and disability scores. Based on these reported outcomes, this novel approach to transaxillary resection of fully formed cervical ribs should be considered a safe and effective operation.Copyright © 2020 Society for Vascular Surgery.
