Abstract

OBJECTIVE: To record symptoms and signs, operative findings, and long-term outcome in operated and nonoperated patients with the diagnosis of thoracic outlet syndrome after a motor vehicle accident. DESIGN: Descriptive prospective study. SETTING: Pain clinic population in the Toronto Hospital (Western Division), Toronto, Ontario, Canada. PATIENTS: Thirty-two patients diagnosed as having thoracic outlet syndrome after injuries sustained in a car accident (based on specific symptoms and signs as well as exclusion of other disorders generating brachialgia). INTERVENTIONS: Conservative management versus transaxillary or supraclavicular exploration of the thoracic outlet. OUTCOME MEASURES: Pain/symptom relief. RESULTS: Most patients presented with pain and paresthesiae, but conspicuous discoloration of the symptomatic extremity was seen in 41%. Osseous anomalies were seen in 22% of the patients in simple neck x-rays. Vascular studies were abnormal in 24% of tested patients. During transaxillary first rib resection in 15 patients, 87% were found to have musculotendinous and less often osseous anomalies compromising primarily the lower trunk of the brachial plexus. Long-term follow up demonstrated very good pain relief (based on patients' estimates) only in 47% of the operated patients and 20% of the conservatively treated patients. Reoperation was necessary in six cases through a supraclavicular decompression with only one patient experiencing substantial improvement with long-term follow-up. The difficulties in diagnosis as well as reasons for failures of conservative and surgical management are discussed, and the authors' current protocol for diagnosis and management is presented.
