Initial experiences of carotid stenting with Palmaz stent

Results of cervical carotid stenting are reported. Twenty-nine lesions in 25 cases were treated by percutaneous transluminal balloon angioplasty combined with stent placement. All the lesions were successfully dilated. There was one embolic complication during the operation that caused deterioration of preoperative symptoms. Stent deformation causing more than 30% luminal narrowing occurred in one case. Instent restenosis with more than 50% luminal narrowing was seen in bilateral lesions in one case. These were satisfactory results as an initial experience, but further improvement in this technique is considered essential especially to avoid embolic complications.
