Abstract:

BACKGROUND: Inferior vena cava filter can prevent pulmonary embolism in clinical practice.
OBJECTIVE: To explore the biocompatibility, safety, surgical indications, and causes and preventive measures of related complications of inferior vena cava filter implantation in preventing pulmonary embolism.
METHODS: A retrospective analysis was performed in 96 patients in the People’s Hospital of Guilin from 2001 to 2011 receiving vena cava filter implantation for treatment of deep venous thrombosis.
RESULTS AND CONCLUSION: Fifty-five patients were implanted with permanent filter, 23 cases were implanted with recyclable filter, and 18 patients were with temporary filter. All the patients were followed up for 8 months to 7 years. Pulmonary embolism occurred in one patient, filter tilting happened in two cases, and slight host response could be seen in one case, all of the above did not influence the treatment. It is indicated that inferior vena cava filter can efficiently prevent pulmonary embolism in clinical practice with good biocompatibility and safety.
