Comparison of light reflection rheography with ascending venography in the diagnosis of lower limb deep venous thrombosis

Abstract

A prospective evaluation of light reflective rheography (LRR) in the diagnosis of acute lower limb deep venous thrombosis (DVT) has been conducted by the comparison of rheographic changes with ascending venography. LRR reliably predicts the absence of DVT, but cannot accurately detect its presence. It is suggested that the technique may be used for surveillance but should not replace venography as a method for establishing the diagnosis of DVT.
