目的：B型主动脉夹层的胸主动脉腔内修复术引发假腔内血栓形成，最终导致主动脉重塑。我们的目的是确定胸主动脉腔内修复术后的假腔血栓形成率（FLTR）是否可以准确预测的指数，表示主动脉弓angularity.Methods的程度：几何形状的48例急性B型主动脉夹层（平均年龄48岁）胸主动脉腔内修复术后重建从术后的计算机断层扫描图像。我们引入了一个新的角度-问号的程度（phi）-来表示主动脉形态。此外，主动脉成角如何影响FLTR的血流动力学参数的基础上进行了研究。最后，建立了FLTR与主动脉成角的预测数学模型，并选择10例患者进行验证。结果：问号形状的程度与FLTR呈负相关（n = 38; P
Objective: Thoracic endovascular aortic repair of type B aortic dissection initiates thrombosis in the false lumen, which eventually results in aortic remodeling. We aimed to determine whether the false lumen thrombosis rate (FLTR) after thoracic endovascular aortic repair can be accurately predicted by an index that expresses the degree of aortic arch angulation.Methods: The geometry of 48 patients with acute type B aortic dissection (mean age, 48 years) after thoracic endovascular aortic repair was reconstructed from postoperative computed tomography images. We introduced a novel angle-the degree of question mark (phi)-to indicate the aortic morphology. Moreover, how aortic angulation influenced the FLTR was investigated based on hemodynamic parameters. Finally, a predicted mathematical model relating FLTR to aortic angulation was proposed, and 10 patients were chosen to validate the model.Results: The degree of question mark shape was shown to negatively correlate with FLTR (n = 38; P
