The only FDA-approved thrombolytic drug for the treatment of pulmonary embolism is tPA. Current studies (including studies by Jeff Kline-"Dr. PE") are investigating the use of TNKase and other agents. For hemodynamically unstable PE (hypotension, RV dysfunction): tPA- give 100 mg over two hours as a drip (no bolus). Heparin must be stopped during infusion and restarted after the tPA has finished.

Update on the Wells Criteria for PE-patients with a score of 4 or less (which means low to moderate probability) can be considered for a "d-dimer negative" rule out approach. This is a bit of a change from the low risk only approach. Additionally, the British Thoracic Society guidelines support the low and moderate risk group patient rule out strategy. So, if you have a low or even moderate risk patient, you can use the approach of obtaining a highly sensitive d-dimer and if it is negative, the hunt for PE is over.

D-Dimer levels are known to be elevated in pregnancy. But how high is too high and can this test be used in the workup of VTE in pregnant patients?

Recent literature indicates that D-dimer levels in each of the three trimesters are approximately 39% higher: 700, 1000, and 1400 ng/dL for each trimester (normal cutoff 500 ng/dL). So, figure out what trimester your patient is in and use the corresponding D-Dimer level for that trimester.
