Carotid stenting with the use of wallstent.

SUMMARY: We performed carotid stenting with Wallstent for 22 cases. The mean stenosis was 74.3 +/- 11.2% before stenting and 14.2 +/- 8.8% after stenting. The technical success (< 40% residual stenosis) was 100%. We experienced 2 embolic complications (one TIA and one minor stroke). Permanent neurological deficits were not encountered in all the patients (0%). Restenosis was observed in 2 cases (12.5%). The both lesions revealed intimal hyperplasia on intravascular ultrasound (IVUS). MRI diffusion weighted study showed that distal embolism happened more often (46.2%) than we expected although most of them were asymptomatic.We must wait for the long term result to conclude that carotid stenting has become one of the treatment modalities.
