Due to its relative simplicity, easy reproducibility, and fair accuracy to diagnose distal thrombus; incorporation of this technique into a routine check of CVC, should be feasible” Patil et al (2019).

Extract:

Response to augmentation maneuvers has been used to diagnose upper extremity thrombosis.[4],[5] Due to its relative simplicity, easy reproducibility, and fair accuracy to diagnose distal thrombus; incorporation of this technique into a routine check of CVC, should be feasible. In conclusion, the Valsalva augmentation in IJV diameter is a valuable test which should be incorporated in addition to the compressibility test, to rule out thrombosis before attempting IJV cannulation.
