- Risk of DVT and PE does go up with pregnancy and increases in each trimester. 1 in 50,000 people develop blood clots in the first trimester with 1 in 10,000 people developing blood clots in the second trimester.
- The risk for PE or DVT in pregnancy is about 3 in every 10,000 people. Comparatively, the risk for pre-eclampsia in pregnancy is 340 in every 10,000 people.
- Two third of the blood clots found in pregnancy are DVTs.
- The D-Dimer cut off in pregnancy is 0.75 in the first trimester, 1 in the second trimester, and 1.25 in the third trimester.
- A perfusion-only VQ scan has the lowest radiation of imaging for PE.
