MRA/MRV for diagnosing PE

By  |  April 5, 2010 | 

In this multi-center trial of 371 patients with suspected PE, all had MRA/MRV, and the results were compared with the reference standard for diagnosing PE, including clinical assessment, Ddimer, VQ scanning, venous USG, and CTA/CTV. They found that technically adequate scans had good testing characteristics (sensitivity and specificity of 78% and 99% for MRA, and 92% and 96% for MRA/MRV) but inadequate scanning rates ranged from 11% to 52% at different centers. MRA/MRV has excellent testing characteristics, but only at centers where technically adequate scans can be routinely performed (abstract)

This large multicenter trial randomized patients with acute VTE to apixaban (10mg BID for 1 week, followed by 5mg BID for 6 months) versus conventional therapy (lovenox-warfarin). The primary outcome was similar between groups (symptomatic VTE or death related to VTE), but major and minor bleeding occurred significantly less often with apixaban. Apixaban is a […]
