Abstract/OtherAbstract:
PURPOSE: To assess primary success and safety of percutaneous transluminal angioplasty (PTA) and/or stenting of ostial/proximal common carotid artery lesions (pCCA) and to compare its 30-day stroke/mortality level with the literature data for surgical options.
METHODS: A total of 147 patients (153 stenoses, 6 recurrent) (71 female; 121 left) with significant diameter stenosis (>70% in symptomatic, n = 46; >85% in asymptomatic, n = 101 patients) of pCCA treated between 1994 and 2006 were retrospectively reviewed. With the exception of one, all procedures were performed using a transfemoral approach. A stent was implanted in 108 (70.5%) of cases. Stents were not available in the early years of our experience, but gradually became a routine practice. Embolic protection devices were used in 16 cases. Follow-up included neurological examination, carotid duplex scan, and office/telephone interview.
RESULTS: Primary technical success was 98.7% (151/153 stenoses). There were no deaths. Periprocedural (<48 hours) neurological complications included 3/153 (2.0%) ipsilateral major strokes and 4/153 (2.6%) TIAs (including one contralateral TIA). There were 8/153 (5.2%) access site hematomas, 1/153 (0.7%) bradycardia, and 1/153 (0.7%) acute left ventricular failure with respiratory distress. Follow-up was achieved in 115/147 patients (78.2%) undergoing 120 procedures for a mean of 24.7 months and revealed one additional contralateral TIA and one additional minor stroke in an asymptomatic patient. In patients with follow-up, the 30-day procedural death/all-stroke rate was 3/120 (2.5%) The cumulative primary patency rate in the 115 patients with follow-up was 97.9% +/- 2.1% at 1 year, 82.0% +/- 7.1% at 4-years, and 73.5% +/- 12.7% at 7 years. The cumulative secondary patency rate was 100% at 1 year, 88.0% +/- 7.0% at 4 years, and 88.0% +/- 11% at 7 years. Log-rank test showed no statistical difference (P = .82) in primary cumulative patency between PTA alone (n = 34) or PTA/stent (n = 86).
CONCLUSION: Transfemoral PTA/stenting appears to be appropriate treatment option for ostial/proximal common carotid artery significant stenoses. This study should also draw attention to the lack of data on natural history or effect of best medical treatment alone for these lesions, making evidence-based decision currently impossible for treatment of symptomatic or asymptomatic ostial and proximal common carotid artery significant stenoses.
