Abstract:
Objective To explore the efficacy and safety of stent-assisted coil embolization of acutely ruptured wide-necked intracranial aneurysms. Methods One hundred and sixty patients with acutely ruptured wide-necked intracranial aneurysms (160 ruptured aneurysms), admitted to and underwent stent-assisted coil embolization in our hospital from January 201l to May 2018, were chosen. The clinical data, outcomes and complications of these patients were retrospectively analyzed. The differences of clinical data between patients with and without complications were compared. Modified Rankin scale (mRS) was used to evaluate the prognoses of these patients. Univariate and multivariate Logistic regression analyses were conducted to analyze the risk factors of prognoses. Results All 160 stents were successfully released. Complete occlusion after endovascular procedures was achieved in 127 patients (79.4％); 17 aneurysms (10.6％) had neck residual and 16 aneurysms (10.0％) had aneurysm residual. Surgery-related complications occurred in 17 patients (10.6％), of which, 6 (3.8％) showed hemorrhagic events and 11 (6.9％) had ischemic events. The distributions of aneurysm sites between patients with ischemia related complications and those without ischemia related complications were statistically different (P<0.05). Poor prognosis was noted in 24 patients (15％) and good prognosis was noted in 136 (85％). The mRS scores, preoperative Hunt-Hess grades and distributions of stent types between patients with good prognosis and patients with poor prognosis were statistically different (P<0.05). Logistic regression analysis indicated that baseline mRS scores ≥4 (OR=39.000, 95％ CI:10.861-140.038, P=0.000), preoperative Hunt-Hess grading IV-V (OR=13.000, 95％CI: 4.063-41.596, P=0.015), and Solitaire stents placement (OR=3.333, 95％CI: 1.332-8.339, P=0.028) were the independent risk factors for poor clinical outcomes in patients with acutely ruptured wide-necked intracranial aneurysms. Conclusion Stent-assisted coil embolization is suggested to be a safe and efficacious way to treat acutely ruptured wide-necked intracranial aneurysms, and patients with baseline mRS scores≥4, preoperative Hunt-Hess grading IV-V and Solitaire stents placement are more prone to having poor clinical outcomes.
