ABSTRACT
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.
ABSTRACT
<p><b>OBJECTIVE</b>To review the influencing factors of the early complication after carotid endarterectomy (CEA).</p><p><b>METHODS</b>Retrospective analysis of clinical data of 509 cases received CEA in Xuan Wu Hospital of Capital Medical University, Liaocheng People's Hospital and Dalian Central Hospital from January 2001 to December 2011. There are 422 male patients and 72 female patients among the 494 patients, 15 patients underwent CEA by stages. The patients were between 35-84 years old,and the mean age was (64 ± 9) years. The complications within 30 days after CEA were analyzed, and find the risk factors for the major adverse events. Chi-square analysis was performed to analyze the correlation between the each variable of the basic characteristics of population, clinical features and intraoperative data and early adverse events after CEA. Logistic regression analysis was used to assess the relationship between a variety of factors and the postoperative complications within 30 days.</p><p><b>RESULTS</b>Technical complete rate of 98.6%, 7 cases of near-total occlusion patients could not been recanalized. Major complications in 30 days after CEA occurred in 20 cases (3.9%), including 6 cases of deaths (1.2%), 9 cases of cerebral infarction (1.8%) and 5 cases of cerebral hemorrhage (1.0%). Secondary complications occurred in 120 cases (23.6%). Univariate analysis showed modified Rankin scale (mRS) ≥ 3 on the incidence of early postoperative complication had significantly difference (χ² =20.517, P < 0.01), multivariate logistic regression analysis revealed that smoking (OR=2.667, 95% CI: 1.048-6.791, P=0.040) and mRS ≥ 3 (OR=8.690, 95% CI: 3.279-23.031, P=0.000) were the significant predictors of 30 days of the end event.</p><p><b>CONCLUSION</b>The complications after CEA are uncommon, the security is proved. Smoking and mRS ≥ 3 can increase the risk of CEA.</p>
