Vena cava-filters are implanted where there is a risk of pulmonary emb
olisation as cases of thrombosis. Permanent vena cava-filters can indu
ce various complications during the remainder of the patient's life. A
case of a 32-year-old woman who became pregnant seven years after the
implantation of a Kimray-Greenfield-Filter and gave birth to a health
y child is presented. During pregnancy and after the birth of a health
y child she suffered from two new thrombotic events. After the deliver
y, a complete thrombosis of the vena cava inferior, both venae iliacae
communes and the right vena renalis were shown by computer-tomography
and phlebography. Inspite of these longterm complications, pregnancy
is not contraindicated after implantation of a permanent vena cava-fil
ter.
