Multicenter StudyThe 6-F nitinol TrapEase inferior vena cava filter: results of a prospective multicenter trial.
The authors report the first results of a new 6-F symmetrically designed permanent nitinol inferior vena cava (IVC) filter, the Cordis TrapEase, evaluated in a multicenter prospective study with 6-months of follow-up. ⋯ This study demonstrates the new nitinol permanent IVC filter to be a safe and an effective device, with a low overall complication rate, for use in patients with thromboembolic disease at high risk of PE.

A novel technique for insertion of the Ash Split-Cath without a peel-away sheath to decrease the potential for air embolism is described. A retrospective review of 62 attempted Ash Split-Cath insertions at three hospitals was made. ⋯ There was no air embolus, hematoma, or immediate catheter malfunction. The authors believe that the occurrence of air embolism during placement of Ash Split-Cath may be lessened by eliminating the use of a peel-away sheath.

Multicenter Study Clinical TrialReteplase in the treatment of peripheral arterial and venous occlusions: a pilot study.
Reteplase, a truncated mutant of tissue plasminogen activator, has been used successfully in the treatment of acute coronary occlusion, but, heretofore, it has not been investigated in the setting of peripheral vascular occlusion. Reteplase is a potential recombinant thrombolytic agent that may offer an appropriate alternative to currently employed plasminogen activators. ⋯ Reteplase appears to be an acceptable alternative thrombolytic agent with a satisfactory safety and efficacy profile in the setting of peripheral arterial and venous occlusion. As such, it may provide an attractive alternative for the treatment of peripheral arterial and venous thrombotic occlusions. However, definitive conclusions must await the results of controlled comparisons of reteplase to other thrombolytic agents.

Multicenter Study Clinical TrialProximity injuries: correlation with results of extremity arteriography.
The results of 170 emergency arteriography procedures in 142 patients who had sustained extremity injuries near major arteries were correlated with the findings from a physical examination conducted prior to arteriography. Radiographically demonstrable significant arterial injuries, which usually required surgical repair, were present at 42 of the 170 injury sites (25%). Major physical findings suggestive of arterial injury were noted at 105 of 170 sites (62%). ⋯ At each of these 65 injury sites, the decision to perform emergency arteriography was based solely on the proximity of the wound to a major artery. In spite of this very low yield in the subgroup of 51 patients without major physical findings, emergency arteriography is still routinely requested for extremity injuries at the authors' institutions. The validity of this policy, a possible reason for its development, and its effect on patient disposition are examined.
