Fig 3.

Exemplary mid-term results from case 3, in which death occurred 13 days after treatment (see Table 1).

A, Angiogram obtained before treatment of an anterior communicating artery aneurysm.

B, Angiogram obtained after GDC treatment of an anterior communicating artery aneurysm.

C, Histologic 5- to 10-μm-thick section of plasticized aneurysm 13 days after treatment shows thrombus extending into the parent vessel (arrows). The scale can be extrapolated from the coil diameter of 0.010 in.

D, ×20 magnification of the inset in shown in C depicts that the thrombus projecting into the feeding vessel is partially coated with endothelium (arrows).

E, ×100 magnification of the area in C indicated by the dashed lines depicts foamy giant cells between the platinum coils (arrow).
