Objective: To demonstrate the safe and effective application of cava filters in pregnant women with deep venous thrombosis.
Setting: Third level health care hospital.
Design: Retrospective, transversal, comparative study.
Statistical analysis: Percentages as summary measure for qualitative variables and comparison by means of Fisher’s and Yates’ exact probability test.
Material and methods: Pregnant patients with deep venous thrombosis were studied, in whom a cava vein filter was placed in the period between January 1997 and June 2005 at the General Hospital of Mexico in Mexico City. Analyzed variables were: age, indication for filter placement, approaching route, trimester of pregnancy, time of fluoroscopy, volume of administered contrast medium, presence or not of hematological alterations, complications of the technique, obstetric complications due to the procedure.
Results: A filter was applied in 84 patients, 58 due to an ileofemoral pedicular thrombus, 15 due to an ileofemoral pedicular thrombus with antecedent of pulmonary embolism, 11 due to re-thrombosis despite adequate anticoagulant treatment. Nine patients were in the 1st gestation trimester, 13 in the 2nd, and the remainder 63 in the 3rd trimester. The percutaneous transfemoral route was used in 63 patients and the transjugular in 21 patients; no major complications occurred. Maternal mortality was zero, there was one product loss in the 1st trimester of gestation. There was no case of pulmonary thromboembolism after the procedure. Comparison of the two approaching routes did not yield statistically significant differences. Exposure to radiation and the amount of administered contrast material had no repercussion on either the mother or the product.
Conclusion: Cava vein filter application in pregnant women with deep venous thrombosis or pulmonary thromboembolism is safe and efficacious.
