Geometrical effect, crack path kinking and deflection, particle bridging and crack shielding are the main toughening mechanisms.

层间增韧的几何效应、裂纹传播路径控制、裂尖屏蔽和颗粒桥联是主要的增韧机理。

If the obstruction is related to kinking rather than intravascular lesions, invasive interventions such as iliac-artery-bypass surgery may not be needed.

如果这种阻塞是与血管的扭曲有关，而不是与血管内的损伤有关，采用侵入性的治疗方法，例如髂骨动脉绕道手术就没有必要了。
