Vena cava syndrome from stenosis of the superior vena cava or inferior vena cava caused by compression from a malignant tumor is a typical clinical condition in patients with advanced-stage malignant disease. Vena cava syndrome is difficult to manage, reducing patients’ quality of life. Vena cava stent placement can improve the symptoms caused by vena cava compression. The Spiral Z stent has high axial force and is suitable for vena cava stenting. However, since it is also a stent that is prone to recoil (so-called jumping), it is necessary to be aware of the characteristics of the stent.
