Treatment of thoracic outlet syndrome with combined scalenectomy and transaxillary first rib resection.
Of a total of 225 patients with suspected thoracic outlet syndrome, 37 (16.4%) underwent surgery. Some eight patients required bilateral operations. One patient had a cervical rib and one a prominent C7 transverse process. A total of 45 limbs were operated on. Thirty-nine procedures were performed as combined scalenectomy and transaxillary first rib resection, four as two-stage scalenectomy and transaxillary first rib resection and two as simple scalenectomy alone. Follow-up from 6 to 60 (mean 17) months was available for 39 operations. A two-tier assessment method was used to improve the accuracy of the results of surgery, including the patient's own evaluation of the benefit of operation communicated to an independent observer and the surgeon's clinical appraisal. Assessment of outcome by the physician was excellent in 54%, good in 28%, fair in 10% and 8% had recurrent symptoms. Similar results were achieved in the patients' subjective evaluation with approximately 50% reporting an excellent outcome, about 40% good and 10% fair. A poor result was not recorded in those who underwent combined scalenectomy and transaxillary first rib resection. A radical surgical approach combining scalenectomy and transaxillary first rib resection is advocated to minimize the recurrence rate and improve results.
