Abstract：Objective To compare the safety and efficacy of two different intracranial stents in coil embolization for the intracranial wide neck aneurysms. Methods Clinical data of 54 patients with 62 wide-neck aneurysms were analyzed retrospectively, who received intracranial stent semi-deploying or post-deploying technique-assisted coil embolization. Twenty-nine patients were treated with Enterprise stents as Enterprise group and 25 with Solitaire stents as Solitaire group. The intraoperative embolization and perioperative complications were analyzed and compared between the two groups. Results There were 70 stents implanted including 38 Enterprise stents and 32 Solitaire stents. All the stents were deployed successfully. There was no significant difference in embolization outcome between two groups (Z=-0.016, P=0.988). Perioperative complications occurred in 5 patients in Enterprise group and 3 in Solitaire group. There were no significant differences in the incidence of perioperative complications between the two groups (x2=0.194, P=0.907). The modified Rankin scale (mRS) score were 0 in 26 patients, 1 in 16, 2 in 8 and 3 in 4 at discharge. There were no significant differences in mRS scores between the two groups (Z=-0.299, P=0.765). All the patients recovered well after the follow-up period of 2 to 36 months and no rebleeding or new infarction occurred. Conclusions For intracranial wide neck aneurysms, Enterprise and Solitaire stent-assisted coil embolization has high technical operability and safety. The stent might be chosen properly according to morphology of parent artery and characteristics of aneurysmal neck.
