Key result
Carotid angioplasty-stenting in patients with occlusive internal carotid arterial disease was associated with 0% short-term mortality and a 4% rate of minor stroke.

Does carotid angioplasty-stenting prevent short-term mortality and stroke in patients with occlusive internal carotid arterial disease?
Carotid angioplasty-stenting is technically feasible and associated with low short-term mortality and stroke rates in patients with occlusive carotid disease.
Suggests acceptable short-term safety in select cases; leaves open comparative efficacy versus endarterectomy.
Carotid angioplasty-stenting (CAS) was attempted in 78 carotid arteries in 74 patients (45 men and 29 women) with occlusive internal carotid arterial disease and was technically successful in 77 of 78 arteries (99%). Of 77 arteries with successful CAS, 58 (75%) were asymptomatic, 15 (20%) were associated with transient ischemic attacks or amaurosis, and 4 (5%) were associated with prior stroke. Of 77 arteries with successful CAS, 34 (44%) were associated with prior carotid endarterectomy with recurrence of occlusive carotid disease, and 43 arteries (56%) were associated with primary CAS. Sixty-eight of 74 patients (92%) who underwent CAS had high-risk features. Cerebral protection was given to 22 of 74 patients (30%). None of the 74 patients (0%) died of CAS. Minor stroke developed in 3 of 74 patients (4%). These data show that CAS is effective for treating symptomatic and asymptomatic patients with occlusive carotid arterial disease.

Pucillo et al. (2003) conducted an observational in Occlusive internal carotid arterial disease (n=74). Carotid angioplasty-stenting (CAS) was evaluated on Short-term mortality and stroke. Carotid angioplasty-stenting in patients with occlusive internal carotid arterial disease was associated with 0% short-term mortality and a 4% rate of minor stroke.
