Summary
Temporary caval filtration (tCF) effectively prevents pulmonary thromboembolic disease (TED) in pregnant patients with deep venous thrombosis (DVT). This retrievable filter offers safe prophylaxis during pregnancy and Cesarean section without long-term complications.
Area of Science:
- Vascular Surgery
- Obstetrics
- Critical Care Medicine
Background:
- Deep venous thrombosis (DVT) poses a significant risk during pregnancy.
- Pulmonary thromboembolic disease (TED) is a serious complication in pregnant patients.
Purpose of the Study:
- To evaluate the benefits of temporary caval filtration (tCF) using a retrievable filter (Tempofilter) in pregnant women.
- To assess the safety and efficacy of tCF for preventing TED in high-risk pregnancies.
Main Methods:
- tCF was implanted percutaneously under local anesthesia and image intensifier guidance in four pregnant patients with severe DVT.
- Prophylaxis was administered during the third trimester, Cesarean section (CS), and postpartum period.
- Procedures were performed in a polyvalent intensive care unit (ICU).
Main Results:
- tCF implantation was technically straightforward with no associated complications.
- No instances of pulmonary embolism (PE) were reported.
- Cesarean sections proceeded without complications for mother or fetus; filters remained in situ for 14-29 days.
Conclusions:
- Temporary caval filtration combined with anticoagulation provides effective TED prophylaxis in pregnant women.
- tCF does not interfere with Cesarean sections and avoids the need for permanent endovascular prostheses.
- This approach offers a safe and effective solution for managing DVT and preventing PE in pregnancy.
