Summary
Temporary vena cava filters effectively prevented pulmonary embolism in deep venous thrombosis patients with floating thrombi. No new or recurrent pulmonary embolism cases occurred, with filters capturing and dissolving emboli.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Cardiology
Background:
- Deep venous thrombosis (DVT) of the lower limbs poses a risk of pulmonary embolism (PE).
- Temporary vena cava filters offer a method for preventing PE in high-risk patients.
Purpose of the Study:
- To evaluate the effectiveness of temporary vena cava filters in preventing primary and recurrent pulmonary embolism in patients with DVT.
- To assess filter performance in conjunction with fibrinolysis or surgical thrombectomy.
Main Methods:
- 24 patients with DVT utilized temporary vena cava filters (Filcard and Lysofilters).
- Diagnosis confirmed via ultrasound (echo-color doppler) and retrograde cavagram.
- Patients received either fibrinolysis (Urokinase) or surgical thrombectomy, alongside heparinization.
- Filters were removed within 10 days.
Main Results:
- No new or recurrent PE cases were observed in the entire group.
- 16 cases showed "very good" results (complete thrombus regression), 3 "good" (nearly complete), and 5 "poor" (unchanged).
- Filters captured large emboli in 2 cases, which were subsequently dissolved by fibrinolysis.
Conclusions:
- Temporary vena cava filters are effective in preventing PE in DVT patients with floating thrombi, especially when combined with fibrinolysis or embolectomy.
- Filters are also effective in preventing PE during surgical embolectomy for occlusive thrombotic diseases.
- The procedure demonstrated a low complication rate, with no filter-related accidents or thrombosis at insertion sites.
