Temporary vena cava filters can cause serious complications like thrombosis and dislocation. Clinicians should carefully consider these risks versus the benefits before placing temporary vena cava filters.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Temporary vena cava filters are used to prevent pulmonary embolism.
- Concerns exist regarding serious adverse events, including filter-related thrombosis.
Purpose of the Study:
- To investigate the clinical complications associated with temporary vena cava filter placement.
Main Methods:
- A consecutive series of 40 patients undergoing temporary vena cava filter insertion were analyzed.
- Data were collected between January 2006 and December 2010 at Saitama Medical Center.
Main Results:
- High rates of major complications were observed: filter thrombosis (10.2%), filter dislocation (10.2%), and catheter-related infection (7.7%).
- One patient (2.5%) experienced massive pulmonary embolism and cardiogenic shock during filter retrieval.
Conclusions:
- Temporary vena cava filter placement is linked to a significant incidence of device-related complications.
- The clinical benefits must be carefully weighed against the potential risks of these complications.
