Venous doppler
However, there is disagreement among authoritative groups regarding the necessary components of the venous ultrasound. Venous ultrasound is the standard imaging test for patients suspected of having lower extremity deep venous thrombosis (DVT). The panel recommends the term chronic postthrombotic change to describe the residual material that persists after the acute presentation of DVT to avoid potential overtreatment of prior thrombus.Īdoption of a single standardized comprehensive duplex ultrasound and a single point-of-care examination will enhance patient safety and clinicians’ confidence. The panel recommends a single point-of-care protocol that minimizes underdiagnoses of proximal DVT.

The use of these recommendations will increase the diagnosis of calf DVT and provide better data to explain the presenting symptoms. This protocol is currently performed in many facilities and is achievable with standard ultrasound equipment and personnel. The panel recommends a comprehensive duplex ultrasound protocol from thigh to ankle with Doppler at selected sites rather than a limited or complete compression-only examination. Recommendations were made after open discussion and by unanimous consensus.

In October 2016, the Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts to evaluate the current evidence to develop recommendations regarding ultrasound protocols for DVT and the terminology used to communicate results to clinicians. Heterogeneity of recommendations can lead to errors including incorrect application of guidelines, confusion among requesting physicians, and incorrect follow-up. Point-of-care ultrasound is recommended in some settings, and there is heterogeneity of these protocols as well. Some protocols use gray-scale ultrasound alone, whereas others include Doppler interrogation.
#Venous doppler serial#
Some protocols include scanning the entire lower extremity, whereas others recommend scans limited to the thigh and knee supplemented with serial testing. There is variability and disagreement among authoritative groups regarding the necessary components of the test.
