Safety of stent-assisted coiling versus coiling-only in treatment of acute ruptured intracranial wide-necked aneurysms: A comparitive study / 第二军医大学学报

ABSTRACT

Objective To compare the peri-procedural complications and mortality between stent-assisted coiling versus coiling-only in the treatment for acute ruptured intracranial wide-necked aneurysms. Methods We retrospectively collected the clinical data of patients with acute ruptured intracranial wide-necked aneurysms who underwent stent-assisted coiling (stent group, n＝133) or coiling-only (coiling-only group, n＝289) between Jan. 2012 and Dec. 2014 in Changhai Hospital of Second Military Medical University. After 1∶1 propensity score matching, 104 cases were matched in each group. Baseline characteristics, peri-procedural complication incidences and mortality were compared between the two groups. Results The baseline characteristics (gender, age, location, relationship with parent vessel, maximum diameter, Hunt-Hess grade and Fisher grade of the aneurysms) were similar in the two groups (all P0.05). The hemorrhagic and thromboembolic complication incidences and mortality in the stent and coiling-only groups were 6.7% (7/104), 3.8% (4/104) and 1.9% (2/104), and 1.9% (4/104), 1.9% (4/104) and 1.0% (1/104), respectively, and the differences were not statistically significant (χ2＝1.858, 0.172, 0.000; P＝0.173, 0.679, 1.000). Conclusion The stent-assisted coiling and coiling-only are both safe and feasible for acute ruptured intracranial wide-necked aneurysms. Stents do not increase the risk of peri-procedural complication.
