Indications - The current indications for the placement of a vena cava filter are as follows :
PLACEMENT ON PERMANENT BASIS
Among patients showing venous thrombosis or a pulmonary embolism, with a contraindication to anticoagulant therapy or showing difficulties to balance with such a treatment.
When the anticoagulant therapy is not sufficient to prevent recurrent pulmonary embolism.
Among patients showing a deep venous thrombosis under anticoagulant therapy and developing complications requiring the stopping of the anticoagulant therapy.
Among patients showing a chronic recurring pulmonary embolism, linked to a pulmonary hypertension and a pulmonary heart.
Following a massive pulmonary embolism phase.
PLACEMENT ON TEMPORARY BASIS
Among patients whose thromboembolic risk is considered as temporary :
Therapeutic Indications
- patients showing contraindications to anticoagulant therapy with a thromboembolic risk (during and/or after surgery for example)
- patients showing complications linked to anticoagulant therapy with a thromboembolic disease
- patients showing failures or insufficiencies with anticoagulant therapy facing a thromboembolic disease :
* temporary inefficiency of the treatment in front of a serious pulmonary embolism
* embolic recurrence under efficient treatment
Preventive Indications
Patients with high thromboembolic risk
- patients with previous serious thromboembolic history
- polytraumatised immobilized patients showing multiple risk factors
- patients going to undergo a surgery with high thrombogenic risk (ex low orthopaedic surgery, traumatologic pelvis surgery, lower limbs surgery, abdo-pelvic surgery)
- in case of pregnancy of a women with high thromboembolic risk
Patients with thromboembolic disease and a transitory pulmonary embolism risk
- fresh thrombus floating in the lower veina cava and/or the iliac vein
- massive pulmonary embolism in case of recurrence with probable mortality
- during and after a embolectomy, surgical or by endovascular route
- transitory contraindication to anticoagulation
