    摘要:

    目的 在多重狭窄的锥形血管中研究支架和球囊形状对血流动力学的影响。方法 建立血管支架植入多重狭窄锥形血管后的血流动力学模型,采用数值模拟方法研究不同形状支架和不同形状球囊的搭配使用对术后血流动力学的影响。结果 分别使用圆柱形球囊和锥形球囊对圆柱形支架进行扩张后,使用锥形球囊扩张能够产生较少的低速血流和低壁面剪应力区域;使用锥形球囊分别对圆柱形支架和锥形支架进行扩张后,扩张圆柱形支架能够产生较少的低速血流和低壁面剪应力区域。结论 多重狭窄锥形血管的血流动力学环境受到植入支架形状和球囊形状的影响;在多重狭窄的锥形血管中,采用锥形球囊扩张圆柱形支架,可获得较好的血流动力学环境,降低支架内再狭窄发生的风险。本文的研究结论能够为临床上介入方案的合理制定提供科学依据。

    Abstract:

    Objective The influence of stent and balloon shape on hemodynamics was studied in tapered vessels with multiple stenosis. Methods The hemodynamic model was established after the implantation of vascular stent in tapered vessel with multiple stenosis. The numerical simulation method was used to study the effect of the combination of different shaped stents and balloons on postoperative hemodynamics. Results When the cylindrical stent was expanded using cylindrical balloon and tapered balloon respectively, the use of tapered balloon for expansion can produce less low-speed blood flow and low TAWSS areas; When tapered balloon was used to expand cylindrical stent and tapered stent respectively, expanding the cylindrical stent can generate less low-speed blood flow and low TAWSS areas. Conclusions The hemodynamic environment of tapered vessel with multiple stenosis was influenced by the shape of stent and balloon. The use of tapered balloon to expand cylindrical stent in tapered vessels with multiple stenosis can achieve favorable hemodynamic environment and reduce the possibility of ISR.The research conclusion of this paper can provide scientific basis for the rational formulation of clinical intervention scheme.
