Long-duration temporary vena cava filter: a prospective 104-case multicenter study.

Background: Nonpermanent caval filters are placed in critical thromboembolic situations in which anticoagulation therapy is transiently contraindicated, ineffective, or the source of complications. The purpose of this study was to assess the safety and effectiveness of a second-generation long-duration temporary caval filter in these situations and compare its utility with that of other temporary filters.

Methods: This prospective study, including patients who underwent temporary caval filtration with the Tempofilter II, was conducted in nine European centers.

[Value of a long duration temporary caval filter in critical thrombo-embolic situations].

In the event of proximal venous thrombosis with a risk of pulmonary embolism, contraindications to or complications of anticoagulant treatment are not uncommon in surgical or intensive care units. These are worrying but temporary situations and represent a classic indication for partial interruption of the inferior vena cava, for which permanent caval filters are not usually suitable. Temporary filters are an attractive option in this context, as long as they are safe and stable, can be left in place long enough to permit normalization of the thrombosis and anticoagulation problems and can then be removed in all circumstances, whether or not they have trapped a thrombus while in place.

Tracheobronchopathia osteochondroplastica presenting at the time of a difficult intubation.

Tracheobronchopathia osteochondroplastica (TO) is a rare and usually benign disorder affecting the trachea and occasionally the bronchi. We describe the case of a 46-year-old woman who was discovered to have TO at the time of a difficult intubation. This case was also unusual since the patient had presented no previous symptoms despite the presence of extensive endotracheal and bronchial lesions.

The Tempofilter: a multicenter study of a new temporary caval filter implantable for up to six weeks.

A multicenter study was conducted to evaluate a new temporary caval filter (Tempofilter) designed to be implanted for up to 6 weeks. A total of 66 patients with a mean age of 51.8 years were enrolled in the study.
