Figure 3.29 Progress of coil embolization executed for representative
case No. 2. Embolism coil forms a cage-shape structure inside
aneurysm as the treatment progresses. Time: (a) 0 s, (b) 23 s,
(c) 5 min 54 s, (d) 6 min 7 s, (e) 6 min 36 s, and (f ) 6 min 59 s.

Figure 3.30 Visualized blood streaming after aneurismal embolization
treatment for case No. 2. This visualization is executed by
injecting a minute air bubble from a y-shaped connector port
into the low.

Coil selection: In embolization treatment, the selection of a coil
with different appearance (with respect to shape, length, diameter,
functionality, etc.) according to the morphology of aneurysm is
required. Through this evaluation, it was conirmed that the proposed
vascular model was useful for the selection of an appropriate coil
for each case. The inal state of coil embolization exerted with three
different coils for a same aneurysm (case No. 1) is shown in Fig. 3.31.
In an actual treatment, when the selection of the coil is improper,
