New technical brief on stroke care published
Research Activities, March 2011, No. 367
A new technical brief highlighting a significant research gap related to stroke care was recently released by the Agency for Healthcare Research and Quality (AHRQ). Neurothrombectomy Devices for Treatment of Acute Ischemic Stoke was prepared by the University of Connecticut/Hartford Hospital Evidence-based Practice Center for AHRQ's Effective Health Care Program and published in the Annals of Internal Medicine. It is the latest of AHRQ's Technical Briefs, which are reports about an emerging or developing technology or treatment that can highlight areas for further research.
The report finds that there is limited high-quality research on the use of neurothrombectomy devices—an emerging technology—for the treatment of acute ischemic stroke. A significant unmet need exists for randomized controlled trials to determine the optimal device(s) to use and the patient populations most likely to benefit from their use. Advances in this technology may ultimately change the way that strokes are treated, but at this point, the specific population that is most likely to benefit from these devices is still under investigation.
A total of seven neurothrombectomy devices are currently in clinical use in the United States. The U.S. Food and Drug Administration (FDA) has cleared two for marketing for use in patients with an acute ischemic stroke to restore blood flow. Other devices have FDA indications ranging from retrieval of intravascular foreign bodies to infusion of fluids into the peripheral vasculature. Data on the use of these various devices are limited.
