Background
- Also consider V/Q in young females in order to minimize radiation exposure to breast tissue
- Also consider V/Q vs CTPA in pregnant females depending on multiple considerations including the above + radiation burden to fetus
Clinical Features
Differential Diagnosis
Workup
- Clinical features suggestive of PE
- Bilateral LE Ultrasound
- Positive-->treat empirically for PE
- Negative-->CTA
- CT (with shield) vs. V/Q is roughly equilivalent radiation exposure
- Bilateral LE Ultrasound
D-Dimer
- D-Dimer MAY BE used with following limits with very poor evidence[1][2]
- 1st trimester: <750 ng/mL (+50% increase from normal lab threshold)
- 2nd trimester: <1000 ng/mL (+100% from normal)
- 3rd trimester: <1250 ng/mL (+150% from normal)
Management
- Heparin and Enoxaparin are safe (coumadin is not)
Disposition
Admit
