    Abstract:
    Between January 1, 1969, and December 31, 1984, 55 operative procedures were carried out in 47 patients to correct subclavian-axillary artery lesions resulting from compression at the thoracic outlet. The most common causes of compression were a long cervical rib (27) and an anomalous first rib (15). Presenting features included claudication, vasomotor phenomena, digital gangrene, and acute limb-threatening ischemia. A combined supraclavicular and infraclavicular approach was preferred. Decompression was best achieved by excision of the cervical rib and the first rib and division of all soft tissue elements. The most common methods of arterial repair were resection-anastomosis (23) and replacement of vein graft (11). Embolic occlusions were frequently present (35). Axillary emboli were amenable to direct revascularization at the time of subclavian artery repair. If possible, more-distal embolic occlusions were managed without recourse to embolectomy catheter manipulations. The mean follow-up was 5 years 8 months (range 4 months to 16 years). Patients were assessed clinically, and the arterial repair was monitored by Doppler ultrasonography, B-mode scanning, and digital subtraction angiography. Of the 39 patients available for follow-up, 35 had no symptoms and four had residual claudication. There were no amputations. In the remaining cases the subclavian-axillary artery segment showed no hemodynamic or anatomic abnormality.
