Methods: We reviewed 16 cases (17 procedures) treated by SMART STENT in Nakamura memorial hospital. The stenosis rates were calculated based on the classification of NASCET. We compared the stenosis rates of carotid artery between pre-treatment and 3, 6, 12, and 24 months after the endovascular treatment. Results: Mean arterial stenosis rate was reduced from 72% to 10% after the treatment. In 8 cases, three and 6 months follow-up angiography after the treatment showed reduction of stenosis 10.9% and 12.4%, respectively. There was one neurological event (TIA). Discussions: It is reported that the balloon expandable stent has a tendency of gradual deterioration of the stenosis rate after the treatment. However, the self-expandable stent (SMART) improves the mean stenosis rates to 10.9% three month after the treatment in our study. The mechanism of long-term improvement of self-expandable stent was considered that the continuous expansion overwhelm the natural stenosis due to the neo-intima. Conclusions: We reported seventeen procedures treated by carotid angioplasty using SMART STENT. No case had restenosis during first year. We found the deterioration of stenosis rate six months after treatment, and thought that non-invasive modality like cervical ultrasonography is enough to check the condition of cervical artery in the three months follow-up examination.}, pages = {39--42}, title = {頸部内頸動脈狭窄に対するSMARTSTENTの使用経験}, volume = {13}, year = {2003} }
