Pulmonary Embolism

This week we are having the talk… The PE talk. It will be one of the most high yield episodes we will ever have on the show. Before listening, please look up the Well’s Score and the PERC rule for reference, and email me with any questions.

    Hi Zac, what do you do if the patient is pregnant and cant have CTPA or V/Q scan or if the patient cant have a CTPA and V/Q scan is inconclusive? also what is the evidence for placing IVC filters?

    • Zack

      Unsure about evidence for IVC filters. Generally speaking Ofer CTA as first line and VQ as second line. If VQ is inconclusive then you make judgement call on risk of PE vs risk of anticoagulation but that situation is rare
