Early effectiveness of isolated pectoralis minor tenotomy in selected patients with neurogenic thoracic outlet syndrome.

OBJECTIVE: This study evaluated the early effectiveness of isolated pectoralis minor tenotomy (PMT) in the surgical treatment of selected patients with neurogenic thoracic outlet syndrome (NTOS) compared with supraclavicular decompression (SCD; as scalenectomy, neurolysis, and first rib resection) plus PMT (SCD+PMT). METHODS: Data were obtained for 200 patients undergoing operative treatment for disabling NTOS between 2008 and 2011. Isolated PMT was offered to 57 patients with physical examination findings limited to the subcoracoid space, and SCD+PMT was offered to 143 with scalene triangle and subcoracoid findings. Functional outcomes were assessed before and 3 months after surgery using the Disabilities of the Arm, Shoulder and Hand (DASH) survey and related instruments. RESULTS: There were no significant differences (P > .05) between PMT and SCD+PMT patients with respect to age (overall, 37 ± 1 years), sex (73% women), side affected (52% right, 14% bilateral), or the frequency of various NTOS symptoms, but fewer PMT patients had a bony anomaly (0% vs 18%; P < .01) or a history of injury (35% vs 61%; P < .01). Mean preoperative DASH scores were similar between PMT and SCD+PMT groups (49.9 ± 3.6 vs 50.8 ± 1.6), but previous use of opiate pain medications was higher in PMT patients (47% vs 20%; P = .0004). PMT was conducted as an outpatient procedure, whereas the mean hospital stay after SCD+PMT was 4.8 ± 0.1 days, with two patients (1%) requiring early reoperations for persistent lymph leaks. Mean DASH scores 3 months after surgery were significantly improved after isolated PMT (29.6 ± 4.2; P < .01) and SCD+PMT (41.5 ± 2.2; P < .01), but the mean extent of improvement in DASH scores was not significantly different in PMT (32% ± 9%) vs SCD+PMT (19% ± 5%). There were also no significant differences in the proportion of PMT vs SCD+PMT patients demonstrating improvement in functional outcome measures (75% vs 72%) or in overall use of opiate medications (35% vs 27%). CONCLUSIONS: Isolated PMT is a low-risk outpatient procedure that is effective for the treatment of selected patients with disabling NTOS, with early outcomes similar to SCD+PMT. These findings emphasize the importance of recognizing subcoracoid brachial plexus compression as part of the spectrum of NTOS and support the role of PMT in surgical management.

Neurovascular problems in the athlete's shoulder.

Competitive athletes are subject to several neurovascular conditions that can affect the upper extremity. These conditions are relatively rare and can be difficult to recognize but are quite important because they can seriously limit athletic performance and may even have limb-threatening consequences. The purpose of this article is to review how to identify and differentiate the major neurovascular conditions affecting the upper extremity in the athlete-patient. We also wish to highlight current concepts and treatment strategies for these problems that can help avoid serious complications and promote successful outcomes. Indeed, with early recognition, proper initial treatment, and prompt referral for comprehensive surgical care, most athletes with these conditions can return to previous levels of performance within several months of diagnosis and definitive treatment.

Comprehensive surgical management of the competitive athlete with effort thrombosis of the subclavian vein (Paget-Schroetter syndrome).

OBJECTIVES: The results of treatment for subclavian vein effort thrombosis were assessed in a series of competitive athletes. METHODS: A retrospective review was conducted of high-performance athletes who underwent multidisciplinary management for venous thoracic outlet syndrome in a specialized referral center. The overall time required to return to athletic activity was assessed with respect to the timing and methods of diagnosis, initial treatment, operative management, and postoperative care. RESULTS: Between January 1997 and January 2007, 32 competitive athletes (29 male and 3 female) were treated for venous thoracic outlet syndrome, of which 31% were in high school, 47% were in college, and 22% were professional. The median age was 20.3 years (range, 16-26 years). Venous duplex ultrasound examination in 21 patients had a diagnostic sensitivity of 71%, and the mean interval between symptoms and definitive venographic diagnosis was 20.2 +/- 5.6 days (range, 1-120 days). Catheter-directed subclavian vein thrombolysis was performed in 26 (81%), with balloon angioplasty in 12 and stent placement in one. Paraclavicular thoracic outlet decompression was performed with circumferential external venolysis alone (56%) or direct axillary-subclavian vein reconstruction (44%), using saphenous vein panel graft bypass (n = 8), reversed saphenous vein graft bypass (n = 3), and saphenous vein patch angioplasty (n = 3). In 19 patients (59%), simultaneous creation of a temporary (12 weeks) adjunctive radiocephalic arteriovenous fistula was done. The mean hospital stay was 5.2 +/- 0.4 days (range, 2-11 days). Seven patients required secondary procedures. Anticoagulation was maintained for 12 weeks. All 32 patients resumed unrestricted use of the upper extremity, with a median interval of 3.5 months between operation and the return to participation in competitive athletics (range, 2-10 months). The overall duration of management from symptoms to full athletic activity was significantly correlated with the time interval from venographic diagnosis to operation (r = 0.820, P < .001) and was longer in patients with persistent symptoms (P < .05) or rethrombosis before referral (P < .01). CONCLUSIONS: Successful outcomes were achieved for the management of effort thrombosis in a series of 32 competitive athletes using a multidisciplinary approach based on (1) early diagnostic venography, thrombolysis, and tertiary referral; (2) paraclavicular thoracic outlet decompression with external venolysis and frequent use of subclavian vein reconstruction; and (3) temporary postoperative anticoagulation, with or without an adjunctive arteriovenous fistula. Optimal outcomes for venous thoracic outlet syndrome depend on early recognition by treating physicians and prompt referral for comprehensive surgical management.
