DVT in Pregnancy

Question 1

What is the occurrence rate of venous thromboembolism (DVT and/or PE) in pregnancies?

Answer 1

0.1%

This statistic highlights the rarity of venous thromboembolism during pregnancy.

Question 2

In what percentage of cases is pregnancy venous thromboembolism associated with thrombophilia?

Answer 2

At least 50%

This includes both inherited and acquired forms of thrombophilia.

Question 3

Why is thrombophilia screening during pregnancy not deemed valuable for treatment?

Answer 3

The results can be unreliable due to changes in coagulation factors.

Pregnancy and treatment for DVT or PE can alter the levels of coagulation factors, affecting screening accuracy.

Question 4

When should thrombophilia screening be conducted for pregnant patients?

Answer 4

After delivery and when anticoagulant treatment has ceased.

This timing allows for more reliable results that can help manage future pregnancies.

Question 5

What percentage of DVT cases during pregnancy occur in the left leg?

Answer 5

Between 70 and 90%

This is due to compression of the left iliac vein by the right iliac artery.

Question 6

What anatomical factor contributes to the higher incidence of iliac vein thrombosis in pregnant patients?

Answer 6

Compression of the left iliac vein by the right iliac artery.

This anatomical relationship is important in understanding DVT occurrences during pregnancy.

Question 7

How is the diagnosis of iliac vein thrombosis acquired?

Answer 7

Generally difficult with compression ultrasonography.

MRDTI

Question 8

What diagnostic method shows high sensitivity and specificity for iliac vein thrombosis in pregnancy?

Answer 8

MRDTI

Magnetic resonance direct thrombus imaging
