Figure 2.10 Carotid artery endarterectomy intra-operative photogram: (a)
Exposure of common carotid artery (double arrow), internal
carotid artery (arrow), and external carotid artery (arrow
head). (b) Blood vessel after clamping, incision from common
carotid artery to internal carotid artery is shown with an arrow
and the internal shunt attached to them with a double arrow.
(c) Peeling off the plaque (arrow) from the internal membrane.
(d) The blood vessel lumen smoothening after the peeling and
the recovery of suficient lumen are conirmed.

2.2.3 Carotid Artery Stenting

In the upstream section of the blood vessel where the stenosis is
located, a protection device such as a ilter or a balloon is deployed
(Fig 2.11a,b). After, with the assistance of the inlation of a small
balloon, a self-expandable stent is deployed covering all the plaque
from internal carotid artery to the common carotid artery (by Boston
Scientiic Japan Co. and Johnson and Johnson Co.). Finally after a
large-size balloon is inlated and the protection device is retrieved
(Figs. 2.12 and 2.13).
