Embolic Protection Device May Be Beneficial After Stenting
FiberNet device associated with low rates of stroke after carotid artery stenting
WEDNESDAY, March 3 (HealthDay News) -- An embolic protection device that captures and removes embolic material is associated with low rates of stroke in high-risk patients undergoing carotid artery stenting, according to a study published in Catheterization and Cardiovascular Interventions.
Subbarao Myla, M.D., from Hoag Memorial Hospital in Newport Beach, Calif., and colleagues used the FiberNet Embolic Protection System (EPS) in 237 high-risk surgical patients undergoing carotid artery stenting. Of these, 20.3 percent were symptomatic (had a transient ischemic attack or stroke).
After 30 days, the researchers found that the combined rate of all death, stroke, and myocardial infarction was 3.0 percent, and the rate of major and minor stroke was 2.1 percent. The rates are lower than those observed in recent trials of other embolic protection devices, they note. The technical success rate of FiberNet deployment and retrieval was 97.5 percent, and 90.9 percent of patients had visible debris within the aspirate.
"The FiberNet EPS, used with commercially available stents, produced low stroke rates following carotid artery stenting in high surgical risk patients presenting with carotid artery disease," Myla and colleagues conclude. "The unique filter design, including aspiration during retrieval, may have contributed to the low 30-day stroke rate reported during carotid artery stenting in patients considered at high risk for complications following carotid endarterectomy."
The study was funded by an educational research grant from Lumen Biomedical Inc., which makes the FiberNet device, and who were also responsible for data collection and analysis and manuscript review.
