A surgeon I work with will perform a 'clipping' repair of a symptomatic leg.
 The patient is being sent to the vascular lab prior to surgery.

Does anyone have a protocol relating to this for RVT's?

Does anyone know of available literature re: this surgical procedure?

Does anyone know the pertinent diagnostic criteria that can be obtained
during physiologic testing?

Info on grading incompetence, optimal transducer frequency, patient
positioning, etc. would be helpful -

thanks
