Erect arteriography: its use in the thoracic outlet syndrome.

Abstract

Conventional arteriography in the supine position at times may not confirm subclavian compression in patients with unequivocal physical findings of the thoracic outlet syndrome. The erect position and weight of the shoulder girdle are important factors in producing the clinical symptoms and findings. Arteriography performed with the patient in the erect sitting position should result in positive arteriographic changes in cases where conventional views have not demonstrated subclavian compression.
