Stent-assisted coiling for unruptured vertebral dissecting aneurysm / 实用医学杂志

ABSTRACT

Objective To evaluate the efficacy of stent-assisted coiling in the treatment of unruptured vertebral dissecting aneurysm. Methods We retrospectively reviewed 59 consecutive patients with unruptured vertebral dissecting aneurysms that underwent endovascular treatment. 31 patients received single stent-assisted coiling, 28 patients received multiple stent-assisted coiling. Results Clinical outcome was favorable in 56 of the 59 patients, the modified Rankin Scale score had no difference in both groups (P = 0.24). The immediate obliteration grade in multiple-stent group was higher than that in single-stent group (75.0% vs. 41.9%, P=0.010). What′s more, the recurrence rate was lower in multiple-stent group (0% vs. 19.4%, P = 0.043). Conclusions Stent-assisted coiling in the treatment of unruptured vertebral dissecting aneurysm is safe and effective , multilayer disposition of stents with coils will decrease the complications and facilitate the aneurysmal occlusion. Larger , prospective studies are necessary to explore the long-term outcomes of reconstruction therapy.
