The rates of major outcome events within 30 days of first treatment did not differ significantly between endovascular treatment and surgery (6.4% vs. 5.9%, respectively, for disabling stroke or death; 10.0% vs. 9.9% for any stroke lasting mo re than 7 days, or death). Cranial neuropathy was reported in 22 (8.7%) surgery patients, but not after endovascular treatment (p<0.0001). Major groin or neck haematoma occurred less often after endovascular treatment than after surgery (three [1.2%] vs 17 [6.7%], p<0.0015). At 1 year after treatment, severe (70-99%) ipsilateral carotid stenosis was more usual after endovascular treatment (25 [14%] vs seven [4%], p<0.001). However, no substantial difference in the rate of ipsilateral stroke was noted with survival analysis up to 3 years after randomization (adjusted hazard ratio=1.04 , 95% CI 0.63-1.70, p=0.9). Endovascular treatment had similar major risks and effectiveness at prevention of stroke during 3 years compared with carotid surgery, but wi th wide CIs. Endovascular treatment had the advantage of avoiding minor complications. |
