Danny Hsu: The Diagnostic Challenge of Pulmonary Embolism During Pregnancy
Danny Hsu, President of THANZ, shared RPTH Journal’s post on LinkedIn, adding:
“Excellent article on the challenging scenario of diagnosing PE in pregnancy!”
RPTH Journal shared a post on LinkedIn, about a recent article by Fanny Collange et al, adding: :
“Diagnosing pulmonary embolism in pregnancy is still harder than we think.
We rely heavily on clinical probability scores like Wells and Geneva, but do they actually work in pregnant women with prior VTE?
A new Highlow ancillary study puts this to the test in 1,110 high-risk pregnancies.
The results are eye-opening
Among 102 suspected PE cases:
- Only 12 were confirmed
- Incidence during pregnancy: 2.6% of suspected cases
- Postpartum: 42% of suspected cases
Now the key finding:
Wells, Geneva, and pregnancy-adapted Geneva scores all showed modest discriminatory power
Translation:
These tools struggle in the exact population where we need them most.
Why?
Because pregnancy changes physiology, symptoms overlap with normal pregnancy, and prior VTE history dominates risk assessment.
Big takeaway:
We urgently need pregnancy-specific PE decision tools to safely reduce imaging and radiation exposure.
This study highlights a major unmet need in maternal thrombosis care.”
