ObjectiveTo study the application of endovascular treatment of the acute ruptured intracranial aneurysms with the hydrocoil. Methods Fifteen patients ( treatment group ) with 17 acute ruptured intracranial aneurysms were treated with the hydrocoils.In the same period,18 patients (control group) with acute ruptured intracranial aneurysms were treated with the bare platinum coil.Results In treatment group,16 aneurysms received dease embolization,and one aneutysm had subtotal embolization.In control group,11 aneurysms achieved dense embolization,7 aneurysms had subtotal embolization.There was a significant difference between the two groups ( x2 =5.402,P ＜ 0.05 ). After follow-up by DSA from 6 months to 1.5 years,no recurrence was showed in the treatment group,while recurrence occurred in 5 cases in the control group aneurysm,with a significant difference between the two groups ( x2 =5.510,P ＜0.05 ).ConclusionThe hydrocoil is an effective therapy for the endovascular treatment of intracranial aneurysms with improving the packing density of intracranial aneurysm embolization and reducing the recurrence rate.

Objective:To investigate risk factors for decompressive craniectomy (DC) after endovascular therapy (EVT) in patients with acute anterior circulation ischemic stroke.Methods:Patients underwent EVT due to acute anterior circulation large vessel occlusion in Liaocheng Brain Hospital from January 2018 to January 2020 were retrospectively included. They were divided into DC group and non-DC group. Univariate and multivariate logistic regression analyses were used to determine risk factors for DC after EVT. Results:A total of 207 patients were enrolled, 126 were male (60.87%), and their age was 66.22±11.24 years old. The baseline National Institutes of Health Stroke Scale (NIHSS) score was 19.84±9.20, and the Alberta Stroke Program Early CT Score (ASPECTS) was 7.98±0.66. The immediate postoperative modified Treatment In Cerebral Ischemia (mTICI) blood flow grade in seven patients (5.80%) was ≤2a, 30 (14.49%) experienced hemorrhagic transformation (HT) after procedure, and 28 (13.5%) received DC. There were statistically significant differences between the DC group and the non-DC group in terms of past stroke history, preoperative NIHSS score and ASPECTS, vascular occlusion site, EVT time, immediate postoperative mTICI ≤2a, and HT (all P<0.05). Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio [ OR] 3.202, 95% confidence interval [ CI] 1.335-9.796; P=0.011), previous stroke history ( OR 2.655, 95% CI 1.016-6.938; P=0.046), high preoperative NIHSS score ( OR 1.074, 95% CI 1.026-1.124; P=0.002), internal carotid artery occlusion ( OR 4.268, 95% CI 1.399-13.024; P=0.011), longer EVT time ( OR 1.010, 95% CI 1.003-1.016; P=0.003), mTICI grade ≤2a ( OR 5.342, 95% CI 1.565-18.227; P=0.007) and postoperative HT ( OR 3.036, 95% CI 1.024-9.004; P=0.045) were independent risk factors for DC. Conclusions:It is not uncommon for patients with acute anterior circulation ischemic stroke to need DC after EVT. Previous stroke history, atrial fibrillation, high baseline NIHSS score, internal carotid artery occlusion, prolonged blood EVT time, mTICI grade ≤2a and postoperative HT are independent predictors of needing DC after EVT.
