研究目的:

在本研究中,利用结合人工智能方法,设计并发症及预后量化模型,驱动多模态数据,搭建急性缺血性卒中取栓术后并发症及预后评估模型,以便提早预知取栓术后的病情发展动态,为临床医生和研究人员提供理论支持。  

Objectives of Study:

In this study, an artificial intelligence–integrated approach was employed to develop a quantitative model for complications and prognosis. Driven by multimodal data, a model for evaluating postoperative complications and prognosis in patients with acute ischemic stroke after thrombectomy was established. This enables the early prediction of the dynamic progression of the patients' conditions following thrombectomy, providing theoretical support for clinicians and researchers.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

对急性大血管闭塞血管内治疗的患者的人口统计学特征、心血管危险因素、改良Rankin量表(mRS)、手术时间、治疗前艾伯塔省卒中计划早期计算机断层扫描评分(ASPECTS)以及血栓切除后脑梗死改良溶栓(mTICI)、术中的应用替罗非班、取栓次数、麻醉方式,血糖情况、侧支循环代偿、恶性脑水肿、出血转化等信息使用Excel表收集管理。 (1)数据收集和预处理:收集急性缺血性卒中取栓患者的临床数据和手术后发症数据,并进行数据清洗和预处理,以确保数据的准确性和可靠性。 (2)特征提取和选择:使用特征工程技术从患者的临床数据中提取相关的特征,例如年龄、性别、血压、血糖、血脂、颅内出血、糖尿病、高血压、MRI等。然后使用特征选择算法选择最相关的特征,以减少维度和提高模型的准确性。 (3)特征融合和预测模型搭建:基于图卷积神经网络方法进行对不同维度、不同类型数据进行有效融合。使用深度学习算法建立预测模型,例如拓扑先验-随机拓扑深度卷积神经网络、随机森林、互作网络等。在建立模型的过程中,需要使用训练集和测试集对模型进行训练和测试,以确定最佳的模型和超参数。 (4)模型评估和改进:使用各种评估指标(如准确率、召回率、F1得分等)对模型进行评估,并使用交叉验证和网格搜索等技术对模型进行改进,以提高其准确性和泛化能力。 (5)实际应用:将最佳的预测模型应用到实际临床中,以帮助医生对急性缺血性卒中取栓患者术后进行早期预测和干预,以改善患者的治疗效果和预后。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data including demographic characteristics, cardiovascular risk factors, modified Rankin Scale (mRS) scores, procedural times, pre-treatment Alberta Stroke Program Early Computed Tomography Score (ASPECTS), modified Thrombolysis in Cerebral Infarction (mTICI) grade post-thrombectomy, intraoperative tirofiban use, number of thrombectomy attempts, anesthesia method, blood glucose levels, collateral circulation compensation, malignant cerebral edema, and hemorrhagic transformation in patients undergoing endovascular therapy for acute large vessel occlusion were collected and managed using Excel spreadsheets.(1) Data collection and preprocessing: Clinical data and postoperative complication data of patients with acute ischemic stroke who underwent thrombectomy were collected, followed by data cleaning and preprocessing to ensure data accuracy and reliability.(2) Feature extraction and selection: Feature engineering techniques were used to extract relevant features from patients’ clinical data, such as age, gender, blood pressure, blood glucose, blood lipids, intracranial hemorrhage, diabetes mellitus, hypertension, and MRI findings. Feature selection algorithms were then applied to identify the most relevant features, aiming to reduce dimensionality and improve model accuracy.(3) Feature fusion and prediction model construction: Graph convolutional neural network (GCN) methods were used for effective fusion of multi-dimensional and multi-type data. Deep learning algorithms were employed to establish prediction models, such as topology-prior random topology deep convolutional neural networks, random forests, and interaction networks. During model construction, training and test sets were used for model training and validation to determine the optimal model and hyperparameters.(4) Model evaluation and improvement: The model was evaluated using various metrics (e.g., accuracy, recall, F1-score), and techniques such as cross-validation and grid search were used for model improvement to enhance its accuracy and generalization ability.(5) Practical application: The optimal prediction model was applied in clinical practice to assist physicians in early prediction and intervention for post-thrombectomy patients with acute ischemic stroke, thereby improving patients’ treatment outcomes and prognosis.
