Does light reflective rheography (LRR) accurately diagnose acute lower limb deep venous thrombosis compared to ascending venography?
Does light reflective rheography (LRR) accurately diagnose acute lower limb deep venous thrombosis compared to ascending venography?
Light reflective rheography can be used for DVT surveillance to predict its absence but cannot replace venography for definitive diagnosis.
Answers are grounded in this paper and cite their sources.
LRR may support DVT exclusion in surveillance; leaves open its diagnostic role versus venography in prospective cohorts.
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.
