Abstract
Patterns of blood flow were examined in the surface vessels of the surgically exposed brain by intracarotid injection of 1% fluorescein and rapid serial photographs timed by a photo-cell signal. As developed in cats and monkeys, and applied in 5 patients during craniotomy, the technique gave a picture of flow patterns in the pial and cortical vascular bed, demonstrating water-shed areas bordering major arterial territories, laminar flow in veins and. in particular, the details of filling and clearing in the fine pial vessels, the superficial cortical capillary bed and in the vascular beds of tumors. Since these features are in finer detail and sharper contrast than seen bv standard X-ray angiography, the method affords a new means of more adequately exami.itng the epicerebral circulation in man during craniotomy for a variety of lesions.
