FIG 2. Exemplary short-term results from case 1, in which death occurred 5 days after treatment (see Table 1).

A, Angiogram obtained before treatment of a medial cerebral artery aneurysm.

B, Angiogram obtained after GDC treatment of a medial cerebral artery aneurysm.

C, Histologic 5- to 10-µm-thick section of plasticized aneurysm 5 days after treatment depicts a thrombus consisting of fibrin and erythrocytes. The scale can be extrapolated from the coil diameter of 0.01 in.

D, x10 magnification of the inset shown in C depicts fibrin clotting and erythrocytes (arrows).

E, x40 magnification of the inset shown in D depicts single macrophages (arrow).
