Cava Filter (cava + filter)
Kinds of Cava Filter Selected AbstractsPulmonary embolism in a patient with severe congenital deficiency for factor V during treatment with fresh frozen plasmaHAEMOPHILIA, Issue 3 2005A. García-Noblejas Summary., Thrombosis is a rare complication in patients with congenital clotting factor deficiencies. In most cases, it is related to inherited procoagulant factors, use of central venous catheters or administration of coagulation factor concentrates. There are only a few case reports about thrombotic events during treatment with fresh frozen plasma (FFP). We report the case of a patient with homozygous inherited factor V deficiency, who developed a pulmonary embolism at a time of treatment with methylene blue treated FFP (MBFFP). The patient had only two other factors predisposing to thrombosis and both were acquired: obesity and bed rest. He started anticoagulant treatment with low molecular weight heparin (LMWH) while the deficient factors were replaced with MBFFP. After 8 days of treatment the patient developed a severe respiratory insufficiency. Pulmonary haemorrhage was considered among the differential diagnosis and LMWH was stopped. An inferior vena cava filter was placed without any further thrombotic complications. To our knowledge, there are no reports about patients with clotting factor deficiencies who developed a thrombotic event during treatment with MBFFP.

(C/Th) Traditionally this condition has been treated with thrombolysis or anticoagulation and support measures. Surgical embolectomy is carried out in situations of hemodynamic instability or contraindication for thrombolysis. We present our results of surgical embolectomy in patients with massive and submassive PE. Methods: Over a three-year period, we have carried out 20 surgical embolectomies for acute PE. The mean age was 66 years, and there were 11 males. In all cases, the diagnosis had been made by a computerized tomography (CT) pulmonary artery angiography. Nine patients (45%) arrived to the operating theater on inotropes, and two of them (10%) with ventilatory support. All patients underwent a median sternotomy, bicaval cannulation for institution of cardiopulmonary bypass (CPB), and main pulmonary arteriotomy for the removal of the thrombus. Results: The mean bypass time was 45 minutes. Two patients (12%) died after being unable to wean off CPB due to right heart failure. Among the 15 survivors, the median ventilation time in the intensive care unit was 24 hours. Twelve patients (60%) required inotropic support postoperatively for right heart failure. All but one survivor (94%) underwent an insertion of a permanent inferior vena cava filter and were anticoagulated with coumarin. The mean follow-up is 9.8 months and is 100% complete, with a survival of 94.5%. All patients were in the World Health Organization (WHO) functional class I, with no re-admissions for respiratory failure. Conclusion: In patients with acute massive or submassive PE, surgical embolectomy offers a valid therapeutic strategy. A right-sided heart failure is the main complication of this condition. [source] Use of a retrievable inferior vena cava filter in term pregnancy: Case report and review of literatureAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 3 2009William MILFORD Venous thromboembolism is a significant cause of morbidity and mortality in obstetrics. Management with anticoagulation can be problematic, especially peripartum. We report the successful placement and retrieval of an inferior vena cava filter as prophylaxis for peripartum pulmonary embolism in a woman with a large, proximal, deep venous thrombosis at term. [source] Clinical features and outcome of pulmonary embolism in childrenBRITISH JOURNAL OF HAEMATOLOGY, Issue 5 2008Tina T. Biss Summary Pulmonary embolism (PE) is rare in childhood but evidence suggests it is under-recognised. Children diagnosed with PE at a large tertiary centre over an 8-year period were retrospectively reviewed. Fifty-six children with radiologically proven PE were identified, 31 males and 25 females, median age 12 years. Eighty-four per cent had symptoms of PE. Risk factors for thromboembolism were present in 54 patients (96·4%); most commonly immobility (58·9%), central venous line (35·7%) and recent surgery (28·6%). Investigation revealed a thrombophilic abnormality in 14/40 patients (35%). Concurrent deep vein thrombosis was confirmed in 31 patients (55·4%), predominantly lower limb. D dimer was elevated at presentation in 26/30 patients (86·7%). Eight patients underwent systemic thrombolysis. An inferior vena cava filter was placed in five patients. Therapy was complicated by major haemorrhage in 12 patients (21·4%). The majority (82·1%) had complete or partial resolution of PE following a median of 3 months anticoagulation. Seven patients had a recurrent thromboembolic event and 12 patients died (mortality 21·4%); five due to thromboembolism (8·9%) and two due to haemorrhage. Risk factors for PE in children are distinct from adults and morbidity and mortality is significant. Multicentre prospective studies are required to determine optimal treatment and long-term outcome of childhood PE.

All patients have had history of deep venous thrombosis and pulmonary embolism with placement of inferior vena caval filters. The patients were not initially considered suitable candidates for the procedure because of risk of dislodgment of previously implanted inferior vena cava filter.

[source] Use of inferior vena cava filters in a tertiary referral centre in AustraliaANZ JOURNAL OF SURGERY, Issue 5 2010Alok Tiwari Abstract Introduction:, To investigate the use of inferior vena cava (IVC) filters in a tertiary referral centre, looking at indication, types of filters and, with temporary/optional filters, removal rates. Methods:, Data was collected from a prospective database of all IVC filters inserted from January 2003 to January 2007. Patients' records and radiological imaging were all reviewed. Results:, 66 patients (40 males) had IVC filters inserted during the study period. The median age of the male patients was 57.5 (21,79) years, and females 56 (24,81). There were 49 (74.2%) temporary/optional filters and 17 (25.8%) permanent filters. The most common indication for filter was a contraindication to anticoagulation for both permanent (64.7%) and temporary/optional filters (77.6%). In the temporary/optional filter group, 38 of 49 (77.6%) patients had documented venous thromboembolism, while in the permanent filter group, this was 14 of 17 (82.4%). Of the optional filters, 22 of 49 (45.8%) have been removed. Conclusion:, More than half (54.2%) of temporary/optional filters were not removed and with potential for long-term complications. A protocol has now being instituted for vascular surgeons to authorize the insertion of filters and to then be responsible for ensuring their removal. [source] Passing sheaths and electrode catheters through inferior vena cava filters: Safer than we think?,CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 6 2009Yousuf Kanjwal MD Abstract Inferior vena cava (IVC) filters are being inserted with increasing frequency for the prevention of pulmonary embolus. Previous case reports have documented the passage of up to three electrode catheters or an individual long sheath through an IVC filter. The current report expands on prior series with regard to the number of devices used. We describe our experience in 10 patients in whom up to five electrode catheters and/or sheaths were placed through an IVC filter using a transfemoral approach under fluoroscopic guidance without routine venography. Devices were successfully introduced and withdrawn in each case without filter dislodgment. Our series illustrates the feasibility and safety of passing multiple electrode catheters and long sheaths through an IVC filter. Evidence is accumulating to suggest that an IVC filter should not be considered an absolute contraindication to performing diagnostic or therapeutic procedures. © 2009 Wiley-Liss, Inc.
