- Stasis of blood
- Blood vessel damage
- Occlusion
- Coagulation of blood is increased
Answer: 3
Occlusion is not a part of the Virchow's triad. In thrombophlebitis, vessel damage stimulates the clotting cascade, which causes the aggregation of platelets at the site of damage. The aggregation is aggravated by increased blood stasis.
Thrombophlebitis: 血栓性静脈炎
Virchow's triad:ウィルヒョーの3要素(血管の障害、血流の停滞、血液性状の変化)
Stasis of blood: 血流停止
Occlusion: 閉塞
