Objective To discuss the complications of percutaneous transluminal stenting for stenosis of internal carotid artery. Methods 478 patients with ICA stenosis were included from 1997 to 2004.All of them took periprocedual anticoagulation treatment, cerebral vascular angiograpgy and cervical Dopller sonography. 195 patients used cerebral protection of filter devices. Among the 283 patients without cerebral protection,202 patients(71.4%) underwent predilation ;66 patients(23.3%) underwent postdilation;3 patients underwent neither. Results Technical success was achieved in all patients(100%). Heart rate was decreased in 25.0% of all the patients (under 50/min). Dislodgment of thrombotic or plaque debris happened in 5 patients during the procudure, 2 of them improved after treatment . 2 of them got dyskinesias of one side,and 1 patient died . 1 patient died of intracerebral hemorrhage(ICH) after the procedure. Stroke and death occurred in 6 patients (1.26%)within 30 d after operation.322 patients(77.8%) were followed up. Restenosis occurred in 17 patients(4.6%). Conclusion Percutaneous transluminal stenting is safe for treatment stenosis of internal carotid artery if operative procedure and periprocedual treatment are standardized,and do the best to prevent periprocedual complications.
