Light reflection rheography and thoracic outlet syndrome.

The authors have studied with a light reflection rheograph (LRR) 112 cases: 54 patients with suspected "thoracic outlet syndrome" (TOS) in the functional phase, 28 patients with phlebothrombosis localized in upper limbs, and a control group of 30 healthy subjects to evaluate the upper limbs' venous outlet. They recorded a good correlation among results obtained with LRR, clinical examination, Doppler, and phlebographic examination. The data obtained lead them to propose this methodology as an important examination in the evaluation of upper thoracic pathology.
