Doppler dupelx US examination of subclavian arteries in search of occlusion or significant narrowing is mandatory.

indirect signs are:

1. a decrease of time to peak velocity in the radial artery of involved side

2. an inverted flow in the vertebral artery of the involved side ( a steal syndrome- sometimes more easily detectable after handgrip exercise).
