A TECHNIQUE for treating cerebrovascular atherosclerosis that usually takes at most 1 hour to perform and costs about one third the price of conventional surgery is in its second year of clinical trials and looks "very promising," according to an investigator who spoke at the Second World Congress of Stroke, held in Washington, DC.
Randall T. Higashida, MD, associate professor of radiology and neurological surgery, Department of Radiology, University of California, San Francisco (UCSF), Medical Center, says the technique, called cerebral percutaneous transluminal angioplasty, has been used successfully in 127 patients during the past year and has had a complication rate of 6%.
The patients ranged from 35 to 80 years of age; two thirds were women and one third men. All were symptomatic, having suffered transient ischemic attacks or stroke, and had high-grade stenosis of greater than 70%. None was considered a good candidate for carotid endarterectomy.
