Digital video subtraction angiography of the cervical and cerebral vasculature.
A digital video subtraction angiography unit developed at the University of Arizona is described. The system allows the angiographic evaluation of the cervical and cerebral vasculature by means of intravenous injection of contrast material. The procedure is performed on outpatients and is reliable, safe, and economical. The authors have evaluated suspected arterial and venous occlusive disease, certain aneurysms and tumors, and postoperative results of vascular bypass procedures and aneurysm clipping. The clinical application of the technique is shown with appropriate case presentations.
