A case of thoracic outlet syndrome with abnormal first rib and thrombosis in the subclavian artery was treated by removal of the first rib and thrombectomy of the subclavian artery. A 54-year-old man complained of a swelling in the left supraclavicular region. X-ray examination revealed abnormal first rib, which formed a non-union between the first and the second rib. Angiography showed complete obstruction of the subclavian artery with collateral circulation. Based on clinical symptoms and X-ray examination he was diagnosed to have thoracic outlet syndrome. Resection of the abnormal first rib, thromboendarterectomy of the subclavian artery and thrombectomy of the brachial artery were performed. During the operation, abnormal shape of the first rib, pseudoarthrosis between the first and the second rib and fibrous band overlaying subclavian artery were found. From pathological findings of the thrombus, the thrombosis of the subclavian artery had grown for about one year. About one year ago, the patient had sustained a traumatic thumb amputation which was treated with pediculed flap. Following the surgery his shoulder was immobilized for 3 weeks. It is suspected that the shoulder immobilization was a trigger of thrombosis in the subclavian artery.
