研究目的:

本研究由全国最大的肾癌伴下腔静脉癌栓微创治疗中心团队发起,旨在系统探索肾癌伴下腔静脉癌栓的血流动力学机制及其临床价值。研究核心目的是通过前瞻性收集患者的临床与影像学资料,构建个体化的下腔静脉-肾静脉-癌栓系统三维模型,并利用ANSYS进行稳态计算流体力学模拟,以期达成三个层面的目标:首先,系统量化不同分级的癌栓对局部关键血流动力学参数(如壁面剪切应力分布、压力梯度与流速场)及继发性侧支循环建立的影响;其次,深入探究这些量化参数与临床重要并发症(包括栓子脱落所致肺栓塞、下肢深静脉血栓形成以及肾淤血相关的肾功能改变)之间的内在关联,并评估术后血流动力学的改变特征;最终,初步建立一个融合术前血流动力学特征与术后改变模式的并发症风险预测与评估框架,为未来实现个体化的围手术期风险评估与手术策略优化奠定理论基础。本研究的理论意义在于,首次将计算流体力学虚拟仿真技术系统、规范地应用于该领域,填补了肾癌伴下腔静脉癌栓血流动力学研究空白,为深入理解“癌栓-血流-侧支循环”的相互作用及术后转归机制提供了全新的研究范式和量化工具。其临床意义更为突出,通过将宏观影像解剖、侧支循环代偿与微观血流动力学功能信息相结合,可为临床医生提供超越传统形态学评估的决策依据。研究成果有望直接应用于术前精准评估手术风险、预测侧支循环状态、优化血管控制等关键手术步骤,并对术后血流动力学恢复进行有效评估,从而助力降低围手术期及远期严重并发症的发生率,最终改善患者的整体预后。  

Objectives of Study:

This study was initiated by the team from the largest minimally invasive treatment center for renal cell carcinoma (RCC) with inferior vena cava (IVC) tumor thrombus in China, aiming to systematically explore the hemodynamic mechanisms of RCC with IVC tumor thrombus and its clinical value. The core objective of the study is to prospectively collect clinical and imaging data of patients, construct individualized three-dimensional (3D) models of the inferior vena cava-renal vein-tumor thrombus system, and perform steady-state computational fluid dynamics (CFD) simulations using ANSYS, with the aim of achieving goals at three levels: Firstly, to systematically quantify the effects of tumor thrombi of different grades on local key hemodynamic parameters (such as wall shear stress distribution, pressure gradient, and flow velocity field) and the establishment of secondary collateral circulation; Secondly, to thoroughly investigate the intrinsic correlation between these quantified parameters and clinically important complications (including pulmonary embolism caused by thrombus detachment, deep venous thrombosis of the lower extremities, and renal function changes related to renal congestion), and to evaluate the characteristics of postoperative hemodynamic changes; finally, to initially establish a complication risk prediction and assessment framework integrating preoperative hemodynamic characteristics and postoperative change patterns, laying a theoretical foundation for the future realization of individualized perioperative risk assessment and surgical strategy optimization. The theoretical significance of this study lies in the first systematic and standardized application of computational fluid dynamics virtual simulation technology in this field, which fills the research gap in the hemodynamics of RCC with IVC tumor thrombus. It provides a novel research paradigm and quantitative tool for in-depth understanding of the interaction between "tumor thrombus-blood flow-collateral circulation" and the mechanism of postoperative outcome. Its clinical significance is more prominent: by combining macroscopic imaging anatomy, collateral circulation compensation, and microscopic hemodynamic function information, it can provide clinicians with decision-making basis beyond traditional morphological assessment. The research results are expected to be directly applied to preoperative accurate assessment of surgical risks, prediction of collateral circulation status, optimization of key surgical steps such as vascular control, and effective evaluation of postoperative hemodynamic recovery. This will help reduce the incidence of severe perioperative and long-term complications, and ultimately improve the overall prognosis of patients.
