ABSTRACT
Objective Few researches have been reported about thromboelastography(TEG)in detecting the complications after stent-assisted coiling for intracranial aneurysms. This study aimed to investigate the value of TEG in predicting thromboembolic complications in patients with intracranial aneurysms after stent-assisted coiling. Methods We retrospectively analyzed the clinical data on 152 cases of intracranial aneurysms undergoing stent-assisted coiling in our department,18 with and 134 without thrombosis. We assessed the effects of antiplatelet drugs by TEG,recorded the general data and postoperative complications,and identified the po-tential risk factors for thromboembolic complications by multivariate logistic regression analysis. Results The incidence rate of aspi-rin resistance was significantly lower than that of clopidogrel resistance(10.5% vs 30.3%,P<0.05). Thromboembolic complications were observed in 18 patients during the perioperative and follow-up periods. Multivariate logistic regression analysis showed that the in-dependent risk factors for thromboembolic complications were the maximum amplitude of TEG(OR=1.152,95% CI:1.002-1.300, P=0.021)and aspirin resistance(OR=4.945,95% CI:1.408-17.375,P=0.013). Conclusion TEG is effective in evaluating the effects of antiplatelet drugs in patients with intracranial aneurysms undergoing stent-assisted coiling. Elevated maximum amplitude of TEG and aspirin resistance may increase the risk of thromboembolic complications.
