[Percutaneous transluminal stenting for stenosis of internal carotid artery: a report of 355 cases].
OBJECTIVE
To discuss the benefits and complications of percutaneous transluminal stenting for stenosis of internal carotid artery (ICA).


METHODS
355 patients with ICA stenosis were included from 1997 to 2003. All of them took periprocedual anticoagulation treatment, cerebral vascular angiography and cervical Doppler sonography. 72 patients used cerebral protection of filter devices. Among the 283 patients without cerebral protection 202 patients (71.38%) underwent predilation, 66 patients (23.32%) underwent postdilation; and 3 patients underwent neither.


RESULTS
The heart rates of 25.0% of all the patients decreased. Dislocation of microemboli happened in 5 patients. 2 of them improved after treatment. 3 of them got dyskinesia of one side. 2 patients (0.56%) died of intracerebral hemorrhage (ICH). 256 patients (84.77%) turned for the better. 260 patients (73.34%) were followed up. Restenosis occurred in 11 patients (4.23%).


CONCLUSIONS
Percutaneous transluminal stenting for stenosis of internal carotid artery is safe if proper periprocedual treatment and operative procedure are taken. However, enough attention should be paid to the occurrence of ICH resulting from over-flow after operation.
