Additional information: h6, h10 (analysis of procedure images).Analysis of images: two images were provided with no date or time stamp.Both are lateral subtracted dsas of the ica.The first shows a small, wide necked pcom aneurysm measuring about 3mm; the pcom arises from the proximal base of the aneurysm.The second image show that the aneurysm has been coiled and that a fred has been implanted, spanning from the distal ica to the level of the ophthalmic artery.There is good wall apposition.There is attenuation of the contrast material in the proximal 1/3 of the stent, compatible with clot; the distal vasculature fills well, so this is likely not flow limiting.No image is provided to show the resolution of the clot that was reported following tirofiban therapy.
