RESUMO

OBJECTIVE: This study was conducted to better define clinical results and understand factors determining responsiveness to surgical treatment for neurogenic thoracic outlet syndrome (NTOS) in adolescent and adult populations. METHODS: A retrospective review was conducted for 189 patients with disabling NTOS who underwent primary supraclavicular decompression (scalenectomy, brachial plexus neurolysis and first rib resection, with or without pectoralis minor tenotomy) from April 2008 to December 2010. Clinical characteristics were compared between 35 adolescent patients (aged<21 years) and 154 adults (aged>21 years). Functional outcome measures were assessed before surgery and at 3- and 6-month follow-up using a composite NTOS Index combining the Disabilities of the Arm, Shoulder and Hand (DASH) survey, the Cervical-Brachial Symptom Questionnaire (CBSQ), and a 10-point visual analog scale (VAS) for pain. RESULTS: Adolescent and adult patients were not significantly different with respect to sex (overall 72.5% female), side affected (58.7% right, 60.3% dominant limb), bony anomalies (23.3%), previous injury (55.6%), coexisting pain disorders (11.1%), and positive responses to scalene muscle anesthetic blocks (95.6%). Compared with adults, adolescent patients had a significantly (P<.05) lower incidence of depression (11.4% vs 41.6%), motor vehicle injury (5.7% vs 20.1%), previous operations (11.4% vs 29.9%), preoperative use of opiate medications (17.1% vs 44.8%), and symptom duration>2 years (24.2% vs 50.0%). Mean preoperative NTOS Index (scale 0-100) was significantly lower in adolescent vs adult patients (46.5±3.6 vs 58.5±1.7; P=.009), and hospital length of stay was 4.4±0.2 vs 4.9±0.1 days (P=.03), but the rate of postoperative complications was no different (overall, 4.2%). Although both groups exhibited significant improvement in functional outcome measures at 3 and 6 months, adolescent patients had significantly lower NTOS Index (10.4±3.1 vs 39.3±3.3; P<.001) and use of opiate medications (11.4% vs 47.4%; P<.001) compared with adults. CONCLUSIONS: Adolescents undergoing supraclavicular decompression for NTOS had more favorable preoperative characteristics and enhanced 3-month and 6-month functional outcomes than adults. Further study is needed to delineate the age-dependent and independent factors that promote optimal surgical outcomes for NTOS.

RESUMO

OBJECTIVES: To describe the spectrum of axillary artery pathology seen in high-performance overhead athletes and the outcomes of current treatment. METHODS: A retrospective review of patients that had undergone management of axillary artery lesions in a specialized center for thoracic outlet syndrome (TOS). Treatment outcomes were assessed with respect to arterial pathology and operative management. RESULTS: Nine male athletes were referred for arterial insufficiency in the dominant arm between January 2000 and August 2010, representing 1.6% of 572 patients treated for TOS (19% of 47 patients treated for arterial TOS). Seven were elite baseball pitchers (six professional, one collegiate), and two were professional baseball coaches with practice pitching responsibilities, with a mean age of 30.9 ± 2.9 years. Presenting symptoms included arm fatigue (five), finger numbness (four), cold hypersensitivity/Raynaud's (two), rest pain (one), and cutaneous fingertip embolism (one). Three patients underwent transcatheter thrombolysis prior to referral, including one with angioplasty and stenting. At angiography and surgical exploration 2.5 ± 0.8 weeks after symptom presentation (range, 1-8 weeks), six patients had occlusion of the distal axillary artery opposite the humeral head either at rest (three) or with arm elevation (three), one had axillary artery dissection with positional occlusion, and two had thrombosis of circumflex humeral artery aneurysms. Five patients had embolic arterial occlusions distal to the elbow. Treatment included segmental axillary artery repair with saphenous vein (n = 7; five interposition bypass grafts and two patch angioplasties), ligation/excision of circumflex humeral artery aneurysms (n = 2), and distal artery thrombectomy/thrombolysis (n = 2). Mean postoperative hospital stay was 3.8 ± 0.5 days, and the time until resumption of unrestricted overhead throwing was 10.8 ± 2.7 weeks. At a median follow-up of 15 months (range, 3-123 months), primary-assisted patency was 89%, and secondary patency was 100%. All nine patients had continued careers in professional baseball, although one retired during long-term follow-up. CONCLUSIONS: Repetitive positional compression of the axillary artery can cause a spectrum of pathology in the overhead athlete, including focal intimal hyperplasia, aneurysm formation, segmental dissection, and branch vessel aneurysms. Prompt recognition of these rare lesions is crucial given their propensity toward thrombosis and distal embolism, with positional arteriography necessary for diagnosis. Full functional recovery can usually be anticipated within several months of surgical treatment, consisting of mobilization and segmental reconstruction of the diseased axillary artery or ligation/excision of branch aneurysms, as well as concomitant management of distal thromboembolism.
