FIG 3. Images in cadaver 1.

A, Anteroposterior view shows the tip of the microcatheter in the sylvian fissure (arrow). The other (dorsal) catheter was traversing the cerebellum at the time this image is obtained.

B, Lateral digital subtraction angiogram obtained during the injection of contrast material through the catheter in the sylvian fissure. The subject is prone. Note the flow of contrast material over the gyri and sulci in the sylvian fissure as it falls away from the catheter tip.
