Technique for placement of experimental indwelling carotid artery catheter.

A technique for placement of an indwelling carotid artery catheter in the rhesus monkey is presented. These indwelling catheters have proved useful in the investigation of regional cerebral blood flow using xenon-133, positive contrast angiography, and fluorescein angiography. Although limited thus far to studies in experimental anemic stroke, this technique could be adapted to a variety of experimental situations in which serial evaluations of the cerebral vasculature are indicated.
