Retrievable Günther Tulip Vena Cava Filter in the prevention of pulmonary embolism in patients with acute deep venous thrombosis in perinatal period.

ABSTRACT

OBJECTIVES: To evaluate the feasibility and efficacy of the retrievable Günther Tulip Vena Cava Filter in the prevention of pulmonary embolism in patients with acute deep vein thrombosis in the perinatal period and to discuss the technical demands associated with the filter's implantation and retrieval. METHODS: Between 1996 until 2007, eight women (mean age 27.4 years, range 20-42 years) with acute deep iliofemoral venous thrombosis in the perinatal period of pregnancy and increased risk of pulmonary embolism during delivery were indicated for retrievable Günther Tulip Vena Cava Filter implantation. All filters were inserted and removed under local anesthesia from the jugular approach. RESULTS: The Günther Tulip Vena Cava Filter was implanted suprarenally in all patients on the day of caesarean delivery. In follow-up cavograms performed just before planned filter removal, no embolus was seen in the filter in any patient. In all patients the filter was retrieved without complications on the 12th day after implantation. CONCLUSIONS: Retrievable Günther Tulip Vena Cava Filters can be inserted and removed in patients during the perinatal period without major complications.
