Abstract

To evaluate whether Willis covered stent implantation yielded angiographic and clinical results were better than those with coil embolization. Eighty-nine patients with cranial internal carotid artery (CICA) aneurysms were treated nonrandomly with covered stents (n = 43, group A) or coil embolization (n = 46, group B). Data on the technical success, procedure time, initial and final angiographic results, and final clinical outcomes were collected and analyzed at >6 months post-procedure. Covered stent placement and coil embolization were successful in all patients, except for one patient in group A. The initial angiographic results showed complete occlusion in 34 group-A patients (80.9%; 95% CI: 69%, 93%) and 24 group-B patients (52.2%; 95% CI: 37%, 67%) (P = 0.004). The final angiographic results indicated complete occlusion in 39 group A patients (39/41, 95.1%; 95% CI: 88%, 102%) and 22 group B patients (48.9%; 95% CI: 34%, 64%) (P < 0.001). The average procedure time was shorter in group A than that in group B (P < 0.001). CICA aneurysm treatment with covered stents yielded better intermediate-term angiographic outcome than those with the recommended approach of coil embolization.
