Compelling new science backs the use of carotid stents for stroke prevention in patients with severe blockages in their carotid (neck) arteries, even if they haven't yet had symptoms like a stroke or mini-stroke.
New research shows that two very different medical procedures, one involving surgery, the other a less invasive procedure using a stent, are equally effective for patients at risk for stroke due to blocked carotid arteries, the arteries in the neck that carry blood and oxygen to the brain.
Thirty percent to 40% of strokes in the elderly are secondary to carotid bifurcation disease. The treatment of internal carotid artery (ICA) stenosis in this patient population is a clinical dilemma. Age more than 80 years is a risk factor for carotid endarterectomy (CEA). Carotid artery stenting (CAS) may be also associated with increased peri-procedural complications in this age group.
The effects of a new long-term subcutaneous vascular access device were studied in access-challenged patients who were poor candidates for fistulas or grafts due to venous obstruction. Bacteremia rates, patency, and function of the Hemodialysis Reliable Outflow (HeRO) Vascular Access Device (Hemosphere Inc, Minneapolis, Minn) were evaluated.
Doctors Raul G. Nogueira, M.D., Guilherme Dabus, M.D., James D. Rabinov, M.D., Christopher S. Ogilvy, M.D., Joshua A. Hirsch, M.D., and Johnny C. Pryor, M.D. explore their experience with Onyx embolization.
