Purpose: This study aimed to assess both nonsurgical and operative treatment outcomes of pediatric and young adult patients with thoracic outlet syndrome (TOS) at a tertiary care pediatric hospital.
Methods: A retrospective chart review of patients diagnosed with TOS, who were seen between January 2010 and August 2022 at a tertiary care pediatric hospital, was conducted. Collected pre- and postoperative data included symptoms, provocative testing (ie, Roo's, Wright's, and Adson's tests), participation in sports or upper-extremity activities, additional operations, and surgical complications. Assessment of operative treatment efficacy was based on pre- and post-provocative testing, pain, venogram results, alleviation of symptoms, and return to previous activity level 6 months after surgery.
Results: Ninety-six patients, (70 females and 26 males) with an average age at onset of 15 ± 4 (4-25) years, met the inclusion criteria for TOS. Among them, 27 had neurogenic TOS, 29 had neurogenic and vasculogenic TOS, 20 had vasculogenic TOS, 19 had Paget-Schroetter Syndrome, and one was asymptomatic. Twenty-six patients were excluded because of less than 6 months of follow-up. Of the remaining 70, 6 (8.6%) patients (4 bilateral and 2 unilateral) underwent nonoperative management with activity modification and physical therapy only, and one was fully discharged because of complete relief of symptoms. Sixty-four (90.1%) patients (45 bilateral and 19 unilateral) underwent surgery. A total of 102 operations were performed. Substantial improvements were observed in provocative maneuvers after surgery. Before surgery, 79.7% were involved in sports or playing musical instruments with repetitive overhead activity, and after surgery, 86.2% of these patients returned to their previous activity level.
Conclusions: Few patients were successfully managed with nonoperative activity modification and physical therapy. In those requiring surgical intervention, first or cervical rib resection with scalenectomy using a supraclavicular approach provided resolution of symptoms with 86.2% of patients being able to return to presymptom sport or activity level.
