A new study shows that one venous puncture, rather than two, is a safe and effective approach to intravascular ultrasound-guided inferior vena cava filter placement in critically-ill patients.
Inferior vena cava filter placement is done to prevent or treat pulmonary emboli or deep venous thrombosis. "The majority of institutions use a dual venous puncture technique, while we use a single venous puncture technique," said Dr. Andrew Gunn, of Massachusetts General Hospital in Boston. "We were interested to know if the different approaches affected technical success, clinical success or the rate of complications with the procedure," Dr. Gunn said.
Better Management Needed for Use of IVC Filters: Research
Researchers have found that the use of Inferior Vena Cava (IVC) filters for the prevention and treatment of venous thrombotic events (VTE) may result in poor outcomes.

In a study of 99 patients, the single puncture technique was technically successful in almost 94% of cases, which is comparable to the dual puncture approach, said Dr. Gunn. The rate for deep venous thrombosis at the venous access site was 2%. This compares to approximately 4% with the double puncture approach, he said.
Dr. Gunn noted that contrast venography is the most common method employed for guiding inferior vena cava filter placement; however, intravascular ultrasound-guided placement is particularly useful in treating critically ill patients, patients who have contrast allergies as well as those who have compromised renal function.

Cancer patients with blood clots gain no benefit from inferior vena cava filter (IVCF) placement to the anticoagulant medication fondaparinux, finds research.
"Intravascular ultrasound-guided placement can be done at the patient's bedside, eliminating the need for time-consuming and often difficult patient transport," he said. About 41% of the inferior vena cava filter placements were done at the bedside. "The filter was slightly more likely to be malpositioned if the procedure was done at the patient's bedside," Dr. Gunn added. Dr. Gunn will present his study at the ARRS annual meeting on April 19 in Washington, DC.

Wide Variation Between Hospitals in Vena Cava Filter Use
To prevent migration of blood clots to the lungs in patients with acute venous thromboembolism (VTE), the frequency of vena cava filter (VCF) use appears to vary widely.
