Other Treatment
Some people cannot take anticoagulant medicines, or they continue
to develop blood clots despite taking the medicines. If surgery or medicines
are not options, other methods of preventing pulmonary embolism may be
considered, such as a vena cava filter.
Other Treatment Choices
A
vena cava filter may be inserted in the large central
vein that passes through the abdomen and returns blood from the body to the
heart (vena cava). This filter can prevent blood clots in the leg or pelvic
veins from traveling to the lungs and heart. These filters may be permanent or
removable.
Studies have shown that vena cava filters help prevent pulmonary
embolism. However, they may be most effective when combined with anticoagulant
therapy.
What To Think About
Vena cava filters are not recommended as the first treatment for
pulmonary embolism. However, they may be considered if you:
- Continue to have pulmonary embolism despite
taking anticoagulant medicine.
- Cannot take anticoagulants because
of bleeding risk.
- Have an increased risk of death or a severely
restricted lifestyle should another pulmonary embolism occur.
Vena cava filters may benefit people who have had a pulmonary
embolism surgically removed (embolectomy) if another pulmonary embolism would
likely be fatal or severely limit a person's lifestyle.
Vena cava filters can cause serious health problems if they
become blocked with one or more blood clots.
Vena cava filters have not been shown so far to lower the death
rate in people with pulmonary embolism.
